This time I will show you how to use vue to achieve tabs and tab switching effects. What are the precautions for using vue to achieve tabs and tab switching effects? The following is a practical case. Let’s take a look. take a look.
I won’t go over the usage of some instructions or basic knowledge in the Vue document with you. Since it is from entry to actual combat, I will directly split some of the effects that need to be achieved in daily projects into modules. If you encounter relevant instructions or don't know how to use them, check the documentation yourself, and then look back at my implementation code. Remember, it’s really important to read through the Vue documentation, very important! Vue here is introduced in the form of a single file. In addition, the code will be optimized step by step in implementation, so don’t worry! The following is a tab with a slightly ugly style, but the function is OK.

<script>
var app = new Vue({
el: "#app",
data: {

methods: {
tabsSwitch: function(tabIndex) {
var tabCardCollection = document.querySelectorAll(".tab-card"),
len = tabCardCollection.length;
for(var i = 0; i < len; i++) {
tabCardCollection[i].style.display = "none";
this.tabsName[i].isActive = false;
}
this.tabsName[tabIndex].isActive = true;
tabCardCollection[tabIndex].style.display = "block";

Vue implements tab switching. The specific code is as follows:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>选项卡</title>
<script src="../js/vue.js"></script>
<style>
li{
list-style: none;
float: left;
margin-right: 20px;
}
</style>
</head>
<body>
<p class="app">
<ul>
<li v-for="(item,index) in list" @click="tab(index)">{{item.tab}}
<p v-show="item.show">
{{item.title}}
</p>
</li>
</ul>
</p>
<script>
let obj=[
{"tab":"选项一","show":true,"title":"1111"},
{"tab":"选项二","show":false,"title":"2222"},
{"tab":"选项三","show":false,"title":"3333"}
];
var vm=new Vue({
el:".app",
data:{
list:obj
},
methods:{
tab:function(index){
for(var i=0;i<this.list.length;i++){
this.list[i].show=false;
if(i==index){
this.list[index].show=true;
}
}
}
}
})
</script>
