VUE的tab页面切换的四种方法

发布时间：2022-04-16 发布网站：脚本宝典

脚本宝典收集整理的这篇文章主要介绍了VUE的tab页面切换的四种方法，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。

1.静态实现方法:

效果图:

在这里插入图片描述

<!DOCTYPE htML>
<html lang="en">
<head>
  <;meta charset="UTF-8">
  <meta http-equiv="X-UA-Compatible" content="IE=Edge">
  <meta name="viewport" content="width=device-width, inITial-scale=1.0">

  <link rel="stylesheet" href="../css/demo.css" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >
</head>
<body>
<div class="demo_warp" id="my">
<ul class="tab_tit">
  <li :class="n==1&#63;'active':''" @click="n=1">标题一</li>
  <li :class="n==2?'active':''" @click="n=2">标题二</li>
  <li :class="n==3?'active':''" @click="n=3">标题三</li>
  <li :class="n==4?'active':''" @click="n=4">标题四</li>
</ul>
<!-- neirong -->
<div class="tab_con">
  <div v-show="n==1">内容一</div>
  <div v-show="n==2">内容二</div>
  <div v-show="n==3">内容三</div>
  <div v-show="n==4">内容四</div>
</div>
</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script> Vue.config.PRoductionTip=false </script>  
<script src="../js/tab.js" type="text/javascript"></script>
</body>
</html>

css

*{
  margin: 0;
  padding: 0;
  box-sizing:border-box;
}
body,html{
 height: 100%;
}
.demo_warp .tab_tit {
  display: flex;
  flex: 1;
  margin:.2rem;
}
.demo_warp .active { 
  color:red;
  background-color: CADetblue;
}
.demo_warp ul li {
  list-style: none;
  width: 23%;
  text-align: center;
  background-color: #ccc;
  margin:0 1%;
}
.demo_warp .tab_con {
  width: 100%;
  height: 3rem;
  border:1px solid rgb(85, 85, 177);
  text-align: center;
}

window.onload=function(){
  new Vue({
    el:'#my',
      data:{//响应式的数据 data变化页面也会跟着变化
     n:1
    }
  })

}

2.第二种模拟动态方法

效果如上图所示:（省略）
代码:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>view的tab交互</title>
  <link rel="stylesheet" href="../css/demo.css" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >
</head>
<body>
<div class="demo_warp" id="my">
<ul class="tab_tit">
  <li v-for="(v,i) in title" :class="n==i?'active':''" @click="n=i">{{v}}</li>
</ul>
<!-- neirong -->
<div class="tab_con">
  <div v-for="(v,i) in con" v-show="n==i">{{v}}</div>
</div>
</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script> Vue.config.productionTip=false </script>  
<script src="../js/tab.js" type="text/javascript"></script>
</body>
</html>

css

*{
  margin: 0;
  padding: 0;
  box-sizing:border-box;
}
body,html{
 height: 100%;
}
.demo_warp .tab_tit {
  display: flex;
  flex: 1;
  margin:.2rem;
}
.demo_warp .active { 
  color:red;
  background-color: cadetblue;
}
.demo_warp ul li {
  list-style: none;
  width: 23%;
  text-align: center;
  background-color: #ccc;
  margin:0 1%;
}
.demo_warp .tab_con {
  width: 100%;
  height: 3rem;
  border:1px solid rgb(85, 85, 177);
  text-align: center;
}

window.onload=function(){
  new Vue({
    el:'#my',
      data:{//响应式的数据 data变化页面也会跟着变化
     n:0,
     title:["标题一","标题二","标题三","标题四"],
     con:["内容一","内容二","内容三","内容四"]
    }
  })
}

3.第三种动态数据方法

效果图:(滚动条的实现方式)

在这里插入图片描述

代码:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>view的tab交互</title>
  <link rel="stylesheet" href="../css/demo.css" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >
</head>
<body>
<div class="demo_warp" id="my">
<ul class="tab_tit">
  <li v-for="(v,i) in lists" :class="n==i?'active':''" @click="n=i">{{v.title}}</li>
</ul>
<!-- neirong -->
<div class="tab_con">
  <div v-for="(v,i) in lists" v-show="n==i">{{v.con}}</div>
</div>
</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script> Vue.config.productionTip=false </script>  
<script src="../js/tab.js" type="text/javascript"></script>
</body>
</html>

css

*{
  margin: 0;
  padding: 0;
  box-sizing:border-box;
}
body,html{
 height: 100%;
}
.demo_warp .tab_tit{
  display: flex;
  justify-content: space-between;
  white-space: nowrap;
  overflow-y: hidden;
  overflow-x: scroll; 
   margin:1% 1% 1% 0;
}
  ::-webkit-scrollbar{
   display: none;
  }
.demo_warp .active { 
  color:red;
  background-color: cadetblue;
}
.demo_warp ul li {
  list-style: none;
  padding:1.2% 3.2%;
  text-align: center;
  background-color: #ccc;
  margin-left: 1%;
}
.demo_warp .tab_con {
  width: 100%;
  height: 3rem;
  border:1px solid rgb(85, 85, 177);
  text-align: center;
}

window.onload=function(){
  new Vue({
    el:'#my',
      data:{//响应式的数据 data变化页面也会跟着变化
     n:0,
     lists:[//可以有很多条数据//数组对象的形式
       {title:'标题一',con:'内容一'},
       {title:'标题二',con:'内容二'},
       {title:'标题三',con:'内容三'},
       {title:'标题四',con:'内容四'},
       {title:'标题五',con:'内容五'},
       {title:'标题六',con:'内容六'},
       {title:'标题七',con:'内容七'},
       {title:'标题八',con:'内容八'},
     ]
    }
  })
}

4.动态实现方法(模拟后台数据实现)

效果图:

代码:

<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">

  <title>view的tab交互</title>
  <link rel="stylesheet" type="text/css" href="../css/demo.css" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" >
</head>
<body>
<div class="demo_warp" id="my">
  <ul class="tab_tit">
    <li v-for="(v,i) in lists" :class="m==i?'active':''" @click="m=i" :key="i.title">{{v.title}}</li>
  </ul>
  <!-- neirong -->
  <div class="tab_con">
    <div v-for="(v,i) in lists" v-show="m==i" :key="i.con">{{v.con}}</div>
  </div>
  <!-- -----------动态数据----------- -->
<ul class="tab_tit">
  <li v-for="(item, index) in itemList" :class="n==index?'active':''" @click="n=index" :key="index">{{item.name}}</li>
</ul>
<!-- neirong -->
<div class="tab_con">
  <div v-for="(item, index) in itemList" v-show="n==index" :key="index">{{item.state}}</div>
</div>
</div>

         lists:[

       ], 
        itemList:[]
       }
     },
    methods:{
      getList:function(){//this:--【函数和定时器的this指向都是window (而我们是要this指向vue实例)】
        VAR that=this;//局部定义改变this指向
        //每执行此方法，提前清空数组，保证往下执行代码，数组为空
        // this.itemList = [];
        axios({
          method:'get',
          url:'http://localhost:4000/list'
        }).then(function(res){
            console.LOG(res);
