In life, there are many people who have impressed me deeply, but there is one person who has left the deepest imprint in my memory. He is my good friend Pan Lin.

I still remember the first time I came into contact with English when I was in third grade. At that time, I couldn't understand it at all. I couldn't write the 26 English letters once they were scrambled, and I couldn't match the uppercase and lowercase letters. When Pan Lin found out, he took time to come to my house every day and teach me English. During the monthly exam, my English score actually reached 91 points! I was overjoyed and thanked him repeatedly. But he smiled and said to me: You're welcome, classmates should help each other. "After that, he still came to my house every day and taught me English. As a result, my English scores improved step by step. By the time of the mid-term exam, I scored 96 points, and by the time of the final exam, my English score reached 100. Min! When I thanked him, he always said: You're welcome, this is what I should do."

Pan Lin not only taught me English words, but also helped me with my English homework! After I finish my English homework, I often ask him to check it. After he checked my homework, he asked me to correct my mistakes. If I didn't know what I was doing, he would patiently explain it to me until I understood it.

This is my good friend Pan Lin, a person who impressed me deeply.

Today the teacher taught us a text called "Last Year's Tree". These texts left a deep impression on me.

The teacher said that this text is very special and has profound meaning. The teacher also asked us to express our impressions when we read the text before. When I finished talking about my impressions, the teacher said that I already understood the true meaning of this text. .

Indeed, this text is indeed very touching. It tells the story of a little bird and a tree who were good friends. One winter, the little bird went to the south. When parting, it said it would come back again to sing for the tree, but when it When he came back, he learned that the tree had been cut down, made into matches, and sold to the village. In order to fulfill its promise to the big tree, the little bird went to find the tree. When it found the tree, its good friend tree was already a flame. There it fulfilled its original promise, sang a song to the tree, and finally flew away.

The teacher opened the book and asked us to read the text and complete the two questions asked in the book. When I finished reading the book and answered the questions, I found that the teacher's eye circles were moist and there were tears in his eyes. It seemed that the teacher was moved .

After we answered the questions, the teacher asked us to read the dialogue in the book with emotion. When I read the dialogue, I saw many students were about to raise their hands, but the teacher read it once before asking us to raise our hands as classmates. When we finished reading, the teacher praised us for reading well, but I still think the teacher read better.

The teacher told us the meaning and asked us to act out the text. Although everyone was amused by the humor of the classmates, I still kept this text in my heart.

In the early morning, drizzle was pouring outside the window. I opened my sleepy eyes and looked at the hazy world outside the window through the curtains. It seemed as if a cold wind passed by the window sill. I sneezed involuntarily. It turned out that the footsteps of winter were coming. , accompanied by the wind and rain has quietly arrived!

I finished washing, put on thick clothes, opened a small umbrella, and walked towards the school shrunk against the wind and rain. oh! This annoying drizzle was dense and scattered in the air, weaving into dense rain curtains, hitting my body with a cold feeling. I tried my best to shrink my body tiredly, struggling to walk in the wind and rain, looking at the street. There were only a few pedestrians, so I couldn’t help but quicken my pace.

Soon, the school was vaguely in front of me. I trotted forward, and suddenly I felt a cold wind passing by. The rain became heavier and heavier. I could only hide under the eaves of the shops on the street to take shelter from the rain. Through the rain curtain, I could see the tall trees on both sides of the street. , swaying in the wind and rain, but also very lonely and desolate, even the grass under the tree has long been unable to stand up, with its head drooped, looking listless, only the air, Washed by the heavy rain, it was so fresh and natural, refreshing and refreshing. I greedily sucked in the early winter air, which was sweet and cool, refreshing to the bottom of my heart. This is the early winter that seems cold and ruthless, but is full of different charm, a fascinating winter!

Slowly, the rain became lighter, and I continued to move forward, heading towards the school. I firmly believed that after the storm, there would be another sunny day!

outside the door. The drizzle was like mist being twisted by the autumn wind, flying in random directions. I walked to the classroom and took a look – it was cloudy and very dark, and I could only vaguely make out a medium-sized, thin teacher in a purple dress standing on the podium.

I walked into the classroom and sat down. A cold wind blew over. The classroom was as cold as a cellar. The cold air seeped up from the seams of his trousers. I shuddered all over. The classmate next to me had a cold face with a yellowish tint and a white tint. So thin that I'm worried. Like a person who has just recovered from a serious illness. But he is not afraid of the cold. Still listen carefully.

Teacher Zeng is our class teacher. He is not only gentle. Be kind to others. head teacher. That day. Take Chinese classes. I didn't attend the class. Reading comic books. He took my comic book away with a pair of bamboo-like hands. Said: "Stop reading comic books. Read this book. There is a lot of knowledge in it." I lowered my head in shame. I came to the office. I looked into his terrible eyes. I was scared. Tears flowed down uncontrollably. He gave me a lecture. I thought: "He must be very disappointed in me. I have to take every lesson of hers well." I stood next to the teacher uneasily. This lesson is unforgettable to me.

Now I know. No matter what the teacher does to us. They all care about us. In this childhood time. The teacher gave us colorful memories. Thank you teacher.

The scene at sunset is a major theme in my creations. Under the setting sun, the world has clear outlines and ambiguous content, a simple atmosphere and complex connotations.

The setting sun is not like the morning sun that arrogantly emphasizes its existence, nor is it like the light of noon that shines directly into the eyes and makes people afraid to get close.

She has steady eyes, gentle agreement, and is feminine.

Another beauty of the sunset is its ephemerality, which reminds people of death. Death is scary, but it is right in front of us, far or near, ferocious or calm, electric or as weak as a stream. It is not among the expectations of most people, but it is destined to be the only thing we can have for a long time – just like after the sunrise, there must be a sunset.

If you take a bus during working hours, if you pay attention to convenience store salespeople and community security guards, you will find that the aging of this city is really happening. At this time, I always think of the sunset – each of us will have a sunset. How can we add warm colors to the impression that is destined to be gray?

Although my age is not suitable for thinking about these issues, if one day fate brings clear sky and changing clouds, I hope to paint a sunset.

This trip to Nanjing allowed me to experience the wonderful combination of simplicity and modern prosperity.

Walking through the Confucius Temple, there are rows of two- and three-story buildings on both sides, with floors paved with stone bricks, a bit like the charm of a Jiangnan water town. The structure of the entire street surrounding Confucius Temple is similar to a commercial pedestrian street, with an alley in the southeast and northwest. Opposite the gate of Confucius Temple is a bridge. One night every year, this bridge will split the reflection of the moon in the water into two. On this side of the bridge, you can only see the reflection of the moon, and the same is true on the other side. .

Then visit Yuejiang Tower, which is close to the Yangtze River. It is 52 meters high and has seven floors. It is one of the four famous buildings in the south of the Yangtze River. Because Yuejiang Tower is located on Lion Mountain in the northwest of Nanjing City, close to the Yangtze River. You can see the Yangtze River Bridge from upstairs. Although the Yangtze River Bridge has a history of 40 years, its majesty can still be seen. It is the first double-decker railway and highway bridge on the Yangtze River designed and built by my country. The upper road bridge is 4,589 meters long and the roadway is 15 meters wide. The lower railway bridge is 6,772 meters long and 14 meters wide. It is paved with double tracks and two trains can run in opposite directions at the same time.

Imagine being surrounded by Ming Dynasty-style buildings and tall buildings in the distance. It feels self-evidently wonderful.

My first impression of the Chinese New Year is: going home. Everyone comes back to their hometown from various cities to celebrate the New Year together. In our family, my parents and I came back from Zhuhai, my cousins, uncles and aunts came back from Hangzhou, and my little aunt came back from Suzhou. Including grandpa, grandma, grandpa and grandma, there are a total of 11 of us celebrating the New Year together this year.

My second impression of the Chinese New Year is: having a reunion dinner. There are many, many dishes, but one must-have dish is fish, because it must be abundant every year.

My third impression of the Chinese New Year is: setting off firecrackers. During the Chinese New Year, there will be a lot of firecrackers and fireworks, crackling, crackling, and making a loud sound. Now I dare to light fireworks with long fuses myself!

My fourth impression of the Chinese New Year is: watching the Spring Festival Gala. The Spring Festival Gala is a New Year's Eve party that lasts a long time. After everyone has a reunion dinner, they sit together and watch. Yesterday I saw it was around 11:30, and my father forced me to go to bed.

My fifth impression of the Chinese New Year is: red envelopes. During the Chinese New Year, everyone sends red envelopes to each other. Children usually only receive red envelopes, but I received many red envelopes. There were many people in our family receiving red envelopes on WeChat, and in the end everyone was busy charging their phones and iPads.

When it comes to my hometown, many things have long been forgotten. But I can't forget the mountains, the water, and the image of my hometown.

My hometown is a simple village. Compared with high-rise buildings, it is not too gorgeous; compared with the bustling traffic of the city, it is not too lively; but it is simple, unknown and selfless.

The mountains in my hometown are tall and majestic, and many trees rise from the ground, becoming a home for many small animals. There are many Chinese herbal medicines on the mountain. As soon as summer comes, many pharmacists climb up the mountains to collect medicinal materials. This is really a natural place!

The water in my hometown is as flat as a mirror. Just because the wind wrinkles its face, it is precisely: the green water is worry-free, but the wind wrinkles its face! The river water is crystal clear, with many fish and shrimp swimming in the water. Many naughty children took off their clothes one by one and jumped into the water to catch them crazily. The sun made the beach at the bottom of the river warm and comfortable.If you want to eat fish and shrimp, you must turn on the fire, otherwise

However, it tastes tasteless. Pour in the oil and throw the small fish and shrimps into the pot "without mercy". After a few minutes, a scent of aroma will hit your face, which will definitely make your mouth water.

The people in my hometown are very honest. The village is not big, but it is perfect. In the morning, green smoke rises from every house, and people in the village work as the sun rises; in the evening, as the sun sets, people take their breath after sunrise. Standing at a high place, my hometown is like a tranquil ink painting, surrounded by mountains and becoming a tourist destination.

The mountains, water, and people in my hometown all have a unique flavor, and here, my hometown is also very rich.

Dear firefighter uncle:

Hello! I am a primary school student. When I was very young, the sharp and urgent calls of fire engines made me aware of you. During the rescue and relief operations again and again, I got to know you better and fell in love with you. Got you.

In my mind, you are so great. When the raging fire burns wantonly, you always rush to the scene as soon as possible. Your appearance can always bring hope of life to those in disaster. You treat every fire-fighting mission as a battle. You are calm, bold and careful, putting your own safety behind your mind. You spray the water very high, you "fly over the walls", and you can always drive away. Each fire demon!

Uncle, aren't you afraid? The fire is so hot and the smoke is so thick. How can you be so obligated and desperate? Don't you have parents and brothers? They must be worried about you all the time, but you know that responsibility is heavier than Mount Tai. , in the face of danger, how much courage you need when you are so calm and calm!

Uncle, aren't you tired? You are eating, drinking water, taking a bath, and sleeping. The alarm bell rings so ruthlessly. Have you ever complained? I have seen that you are in the hot summer. During the day, you braved the scorching heat and wore thick chemical protective suits to rush to the rescue site immediately to deal with chemical leaks; I have seen you braving the cold and freezing weather, holding your hands numb from the cold. High-pressure water gun, the red liquid dripping down the mouth of the water gun is the blood flowing from your frozen hands!

Uncle, aren't you bothered? You are overwhelmed with the task of putting out fires alone. Now, someone has committed suicide, someone has been caught in the elevator, a child has his hand stuck in a hoop, and there are endless situations that you can't even imagine, everywhere. We need you, but you always come forward when needed. You seem to be proficient in all kinds of martial arts. How much I envy and respect you!

I know that there are many fires caused by us children playing with fire. I once caused a lawn to burn instantly because of playing with fire, causing you to come to put out the fire on the first day of the new year. How regretful I am! That time, I saw the execution You are so tall in the mission, and I have secretly made up my mind that when I grow up, I will become a person like you! TV and newspapers often report on various types of fires, and some of the pictures are too horrific to watch. This makes me understand the horror of fires. I also know how important it is to learn fire prevention knowledge. Now, I pay great attention to fire prevention at home and at school. I will consciously prevent fires in the power supply and gas at home. Sometimes I even remind my parents! Once a fire breaks out, I have also learned how to escape. I am not a child. What about the little firefighter?

Uncle, today’s fire-fighting equipment is becoming more and more advanced. I must work hard to learn cultural knowledge. In the future, I will not only learn from your dedication, but also invent and create more and better alternatives. I have always thought that if I rush into a fire If firefighters can be replaced by robots, how many fire officers and soldiers can be protected?

Dear firefighter uncles, you will always be my role model. In my heart, you are heroes. Thank you for everything you have done for me. I salute you!

Finally, I wish you peace and happiness forever!

Dear firefighter uncle:

Whenever fire is mentioned, I believe the first thing many people think of is firefighters. Each of you is a hero and the nemesis of fire. You saved so many lives regardless of your own safety. How many of you have paid your precious lives for this! You are like an angel, healing the wounds of the suffering people; you are like a light, guiding people in desperate situations to see hope; you are like Stars, although they are small, can still shine with their own light. For the sake of everyone's safety, you gave up the opportunity to get along with your family. This spirit of caring for everyone at home is worth learning. You are the heroes in my heart forever.

When you put on heavy and stuffy arson suits and rush into the blazing flames, it's such a torment, but you still choose to bet with your life and win everyone's trust. In one minute, the police were dispatched; in one minute, they were fully armed and climbed to the 10th floor; in one minute, they walked 230 meters with a heavy load. One minute, climb the rope three times… For firefighters: one minute means life and protection.

This is you – firefighters, the cutest people in peacetime. You are firefighters. You respond to various challenges at the disaster scene through hard training. You use your flesh and blood to build a safe haven. In the face of disasters, you are warriors who go against the fire. You stand up for your pure faith. Out of the ordinary and great.

You are the angels of mankind and the nemesis of fire. You are angels when you lend a helping hand to those in need. The people in the world who have been saved by you must have many things to say to you. In short, thousands of words can be condensed into one sentence, that is: "Thank you!"

Dear firefighter uncles, I love you, your dedication, and your unity. Maybe you are so inconspicuous, but I love you!

Sample letter of thanks to firefighters (8 selected articles) (Part 3)

Dear firefighter uncle:

Hello, I wonder if you can remember me. I am a young reporter who visited the Mountain Resort Fire Squadron a few days ago!

I remember that day we stood in a neat line and solemnly walked into the sacred fire brigade gate. You first took us into the film and television hall, where you enthusiastically told us a lot of fire protection knowledge. I found a room next to the movie theater. There seemed to be a lot of signs in it, and they couldn't be seen clearly from a distance through the door. I had no choice but to follow the team and walk back. I looked at it reluctantly, thinking that I must see what happened.

Then you took us to the playground, where you introduced us to the male and female ports of the fire pipe. The female port is larger than the male port and can be locked; the surface of the pipe is made of cloth and there is a layer of waterproof material inside. At this time, I suddenly had an idea and asked: "What should you do if you encounter a fire like gasoline burning?" You replied: "Just cover it with foam." You mysteriously said Added: "You will know the details later." Then you introduced high-temperature-proof clothing and belts. The clothes range from black to red. The black ones are for earthquakes, and vice versa are for fires. The belt has small tools for cutting branches and a rope to prevent getting lost. It is really professional grade. But I kept thinking in my mind, when will the details be told to me? I am looking forward to it more and more.

You also took us to see cars. The smallest ones are small off-road vehicles and off-road motorcycles, which are used for patrolling in the mountains. The other two small ones are used for emergency rescue, car accidents, earthquakes, etc. Finally, we arrived at the second largest car. This one was imported from Germany and is worth hundreds of thousands. It has four pipes on it, two red, one green and one yellow. . The green one catches water from a fire hydrant or lake. "As for this yellow one!" he said, "it's made of spray foam. These foams isolate the gasoline and the air." The stone in my heart finally fell to the ground. "There are bigger cars than this!" We continued walking forward. "Wow!" We said in unison, because the car was so big, and there was a crane electric saw behind it, which was used to cut trees and steel bars. There are firefighting suits and blowers in the garage with names on the hangers. The blowers are used to put out wildfires. Then we visited our uncles’ rooms. There were famous names written on the beds and the quilts were folded into squares, which was very neat. I can’t help but stand in awe of you after reading this!

Finally, you took us to the room I had always wondered about, and you opened the door to the new world. I was ecstatic but extremely nervous. I went in, opened and closed my eyes, and saw clearly. It turned out to be a record of your various glorious awards! There are so many, it’s really admirable! There is a photo album in it, which records your process of dealing with the "human-headed wasp" , the human-headed wasp is so poisonous, but you are not afraid, how brave!

Uncle firefighter, you have a lot that I should learn from you: a square quilt, not a bad bed, brave, strong… You still have many, many things worth learning from, I have to work harder!

I wish the firefighter uncle good luck in his work!

When I see you disregarding your own safety to save those trapped in the raging fire, but you don’t ask for anything in return. No matter how hot or cold you are, you still persist. Your selfless spirit is profound. I was deeply moved.

Uncle firefighters, you are always ready.

People lose their lives. You never flinch when you arrive at a fire. You rush into the fire risklessly to save people. The firefighters outside spray their water cannons very high. Some of them even sacrificed their lives because the fire was so intense. You have exchanged your own lives for the lives of so many people. I really admire you!

Uncle, your job is too dangerous! The bigger the fire, the more courageous you must move forward. But you must also protect your own lives, because your relatives and friends are thinking of you.

I also want to assure you that you must use fire in a civilized manner and not play with fire in your life. In my studies, I will also pay more attention to fire protection knowledge and advanced fire protection science. Finally, I wish you peace and happiness forever!

Dear firefighter uncle:

Hello!

I was no stranger to you when I was young, because my father was a firefighter, and I often heard him tell me about your heroic deeds. When I was a kid, we lived next to my dad’s fire brigade, and we often heard the high-pitched and urgent screams of fire trucks. You are always ready.

When implementing the code in the previous Aside.vue, the first-level menu is actually very simple. Just use el-menu and el-menu-item. The Side.vue code is as follows:

<template>
    <div>
        <el-menu>
            <el-menu-item>一级菜单1</el-menu-item>
            <el-menu-item>一级菜单2</el-menu-item>
            <el-menu-item>一级菜单3</el-menu-item>
        </el-menu>
    </div>
</template>
<script>
    export default {
        name: "Aside"
    }
</script>
<style scoped>
</style>

The renderings are as follows:

Set menu background color and text color

Set the -color and text-color properties in el-menu

<template>
    <div>
        <el-menu background-color="#545c64" text-color="#ffffff">
            <el-menu-item>一级菜单1</el-menu-item>
            <el-menu-item>一级菜单2</el-menu-item>
            <el-menu-item>一级菜单3</el-menu-item>
        </el-menu>
    </div>
</template>

Set the menu text color after selection

Set the -text-color attribute, but the index attribute must be set in the submenu that needs to take effect, otherwise it will not take effect. Do not set the index first.

<template>
    <div>
        <el-menu background-color="#545c64" text-color="#ffffff"
                 active-text-color="#ffd04b">
            <el-menu-item>一级菜单1</el-menu-item>
            <el-menu-item>一级菜单2</el-menu-item>
            <el-menu-item>一级菜单3</el-menu-item>
        </el-menu>
    </div>
</template>

You can see that after I click, the color of the menu text does not change. Now let’s add the index attribute.

<template>
    <div>
        <el-menu background-color="#545c64" text-color="#ffffff"
                 active-text-color="#ffd04b">
            <el-menu-item index="1">一级菜单1</el-menu-item>
            <el-menu-item index="2">一级菜单2</el-menu-item>
            <el-menu-item index="3">一级菜单3</el-menu-item>
        </el-menu>
    </div>
</template>

In the picture above, we can see that there is no selected menu at first. You can set the default selected menu by setting – to the corresponding index value. For example, I set the second menu to be selected by default, and the index of the second menu is 2. , so we add -="2" to el-menu

<template>
    <div>
        <el-menu background-color="#545c64" text-color="#ffffff"
                 active-text-color="#ffd04b" default-active="2">
            <el-menu-item index="1">一级菜单1</el-menu-item>
            <el-menu-item index="2">一级菜单2</el-menu-item>
            <el-menu-item index="3">一级菜单3</el-menu-item>
        </el-menu>
    </div>
</template>

After refreshing the page, the second menu is selected by default

Add icon to menu

Adding icons to the menu will make our menu look more beautiful and comfortable. When it comes to the use of icons, you can refer to my previous article: Use of Icon in Vue Development Example (08)

Just use the i tag, add it in front of the menu name, XXX is the name of the icon.

<template>
    <div>
        <el-menu background-color="#545c64" text-color="#ffffff"
                 active-text-color="#ffd04b" default-active="2">
            <el-menu-item index="1"><i class="el-icon-location"></i>一级菜单1</el-menu-item>
            <el-menu-item index="2"><i class="el-icon-document"></i>一级菜单2</el-menu-item>
            <el-menu-item index="3"><i class="el-icon-setting"></i>一级菜单3</el-menu-item>
        </el-menu>
    </div>
</template>

Secondary menu implements secondary menu

Modify the first-level menu 1 to the second-level menu

<template>
    <div>
        <el-menu background-color="#545c64" text-color="#ffffff"
                 active-text-color="#ffd04b" default-active="2" >
            <el-submenu index="1">
                <template slot="title"><i class="el-icon-location"></i><span>一级菜单1</span></template>
                <el-menu-item index="1-1">选项1</el-menu-item>
                <el-menu-item index="1-2">选项2</el-menu-item>
            </el-submenu>
            <el-menu-item index="2"><i class="el-icon-document"></i>一级菜单2</el-menu-item>
            <el-menu-item index="3"><i class="el-icon-setting"></i>一级菜单3</el-menu-item>
        </el-menu>
    </div>
</template>

Modify the analysis [actually very simple]:

Change el-menu to el-button name, wrap the icon with a label, and add the slot="title" attribute, otherwise the menu style will be incorrect. Add two new el-menu-items.Three-level menu implements three-level menu

The modification method is the same as the secondary menu, that is, adding an extra layer

<template>
    <div>
        <el-menu background-color="#545c64" text-color="#ffffff"
                 active-text-color="#ffd04b" default-active="2">
            <el-submenu index="1">
                <template slot="title"><i class="el-icon-location"></i><span>一级菜单1</span></template>
                <el-submenu index="1-1">
                    <template slot="title"><i class="el-icon-location"></i><span>选项1</span></template>
                    <el-menu-item index="1-1-1">选项1-1</el-menu-item>
                    <el-menu-item index="1-1-2">选项1-2</el-menu-item>
                </el-submenu>
                <el-submenu index="1-2">
                    <template slot="title"><i class="el-icon-location"></i><span>选项2</span></template>
                    <el-menu-item index="1-2-1">选项2-1</el-menu-item>
                    <el-menu-item index="1-2-2">选项2-2</el-menu-item>
                </el-submenu>
            </el-submenu>
            <el-menu-item index="2"><i class="el-icon-document"></i>一级菜单2</el-menu-item>
            <el-menu-item index="3"><i class="el-icon-setting"></i>一级菜单3</el-menu-item>
        </el-menu>
    </div>
</template>
<script>
    export default {
        name: "Aside"
    }
</script>
<style scoped>
</style>

Join related events

Open open, close close, select 3 events

Add three event attributes to el-menu and write the corresponding

<template>
    <div>
        <el-menu background-color="#545c64" text-color="#ffffff"
                 active-text-color="#ffd04b" default-active="2"
                 @open="handleOpen"
                 @close="handleClose"
                 @select="handSelect">
            <el-submenu index="1">
                <template slot="title"><i class="el-icon-location"></i><span>一级菜单1</span></template>
                <el-submenu index="1-1">
                    <template slot="title"><i class="el-icon-location"></i><span>选项1</span></template>
                    <el-menu-item index="1-1-1">选项1-1</el-menu-item>
                    <el-menu-item index="1-1-2">选项1-2</el-menu-item>
                </el-submenu>
                <el-submenu index="1-2">
                    <template slot="title"><i class="el-icon-location"></i><span>选项2</span></template>
                    <el-menu-item index="1-2-1">选项2-1</el-menu-item>
                    <el-menu-item index="1-2-2">选项2-2</el-menu-item>
                </el-submenu>
            </el-submenu>
            <el-menu-item index="2"><i class="el-icon-document"></i>一级菜单2</el-menu-item>
            <el-menu-item index="3"><i class="el-icon-setting"></i>一级菜单3</el-menu-item>
        </el-menu>
    </div>
</template>
<script>
    export default {
        name: "Aside",
        methods: {
            handleOpen(key, keyPath) {
                console.log("打开:",key, keyPath);
            },
            handleClose(key, keyPath) {
                console.log("关闭:",key, keyPath);
            },
            handSelect(key, keyPath) {
                console.log("选择:",key, keyPath);
            }
        }
    }
</script>
<style scoped>
</style>

Implement click menu jump

When you click a menu item, the corresponding page can be displayed in the Main window on the right.

Create 3 pages Main1.vue Main2.vue Main2.vue

<template>
    <div>
       这是Main1
    </div>
</template>
<script>
    export default {
        name: "Main1"
    }
</script>
<style scoped>
</style>

<template>
    <div>
       这是Main2
    </div>
</template>
<script>
    export default {
        name: "Main2"
    }
</script>
<style scoped>
</style>

<template>
    <div>
       这是Main3
    </div>
</template>
<script>
    export default {
        name: "Main3"
    }
</script>
<style scoped>
</style>

Configure the route and create .js under src. The main route index is created, which is the three index sub-routes of the main page entered. They are used for jumps and correspond to the main1 main2 main3 pages respectively. The jump position of the sub-route is the Main position of the index, because our management system only needs the Main position to change, and the header, left navigation, and bottom do not need to be changed.

.js is as follows:


import VueRouter from "vue-router"
import Index from "./components/Index";
const routes = [
    //一级路由
    {
        path: '/index',
        name: 'index',
        component: Index,
        //路由嵌套
        children:[
            {path: '/index/menu1',component: () => import('./components/Main1.vue')},
            {path: '/index/menu2',component: () => import('./components/Main2.vue')},
            {path: '/index/menu3',component: () => import('./components/Main3.vue')}
        ]
    }
]
const router = new VueRouter({
    mode:'history',
    routes
})
export  default router;

Configure this route in main.js to make the route effective

In the original Index.vue page, set the routing jump position. Here we can modify the bit -view in the original Main position.

Add routing configuration to menu

Here we use the first-level menu, which is simple and convenient, and modify the code of Aside.vue.

Add attributes to el-menu

In the index of el-menu-item, set the corresponding sub-route

<template>
    <div style="height: 100%;">
        <el-menu background-color="#545c64" text-color="#ffffff"
                 active-text-color="#ffd04b" class="el-menu-vertical-demo"
                    router>
            <el-menu-item index="/index/menu1"><i class="el-icon-location"></i>一级菜单1</el-menu-item>
            <el-menu-item index="/index/menu2"><i class="el-icon-document"></i>一级菜单2</el-menu-item>
            <el-menu-item index="/index/menu3"><i class="el-icon-setting"></i>一级菜单3</el-menu-item>
        </el-menu>
    </div>
</template>
<script>
    export default {
        name: "Aside"
    }
</script>
<style scoped>
    .el-menu-vertical-demo{
        height: 100%;
    }
</style>

We enter the index main route

Click on the left navigation menu

Handle the case where the default Main window is empty

When we first entered index routing, we saw that there was nothing in the main window.

This obviously doesn’t look good, so we can set the default jump position as follows:

Add a new route to the sub-route for default jump. Configure the value of this sub-route in the main route.

The above is actually a redirection operation. When the index route is entered directly, it will jump to the Main route by default, so that there will be a default page.

Below we only enter index in the address bar. After pressing Enter, "/Main" will be added by default, which directly redirects. At the same time, the page in the Main window also displays the page we specified.
