一.简单tab切换案例

使用vue.js实现tab切换很简单，先使用v-for把数据遍历渲染到页面上，v-for中有一个index表示索引，将index作为参数传入到tab（index）这个函数中，在data中定义一个num变量，在title中如果index==num,这个title就会添加一个acive的class。当然，这个num是需要在tab（）这个函数中不断改变的，需要将传入的索引值赋值给num，这样在.tabCon里，我们就可以用v-show做下判断。v-show=”index==num”,如果等于的话，当前的内容就会显示。否则隐藏。

<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>Document</title><style type="text/css">*{padding: 0;margin: 0}#app{width: 500px;height: 300px;margin: 30px auto;background-color: #ddd;}#app ul{height: 50px;line-height: 50px;width: 100%;background-color: #999;cursor: pointer;}#app ul li{display: inline-block;padding:0 10px;color:#fff;}#app .active{background:#eee;color: #f00;}.tabCon{padding: 20px;}</style></head><body><!--这里是html结构--><div id="app">    <ul>     <li v-for="(item,index) in tabs" :class="{active:index == num}"@click="tab(index)">{{item}}</li>    </ul>    <div class="tabCon">        <div v-for='(itemCon,index) in tabContents' v-show="index == num">{{itemCon}}</div>    </div></div><script type="text/javascript" src='js/vue.js'></script><script>var vm = new Vue({    el: '#app',    data: {        tabs: ["水果", "服饰","头饰"],        tabContents: ["苹果", "连衣裙","发夹"],        num: 0    },    methods: {        tab(index) {            this.num = index;        }    }});</script></body></html>

二.Vue.js编写tab滑块效果

<!DOCTYPE html><html lang="en"><head>  <meta charset="UTF-8">  <meta name="viewport" content="width=device-width, initial-scale=1.0">  <meta http-equiv="X-UA-Compatible" content="ie=edge">   <title>Vue.js编写tab滑块效果</title>  <style>    *{margin:0;padding:0;}    #tabPanel .itemname{height:40px;width:180px;margin-bottom:10px;}    #tabPanel .itemcontent{height:40px;width:180px;}    #tabPanel .addbtn{width:100px;height:30px;}    #tabPanel .active{background:#eee;}    #tabPanel{height:340px;width:500px;margin:100px auto;}    #tabPanel .tab{height:40px;background:#ccc;margin-top:10px;}    #tabPanel .tab ul li{list-style: none;float:left;width:80px;text-align:center;    line-height:40px;}    #tabPanel .content{height:300px;width:500px;background:#eee;}  </style> </head><body><div id="tabPanel"><label>添加滑块名称：<input type="text" v-model="tabItem" class="itemname"></label><br><label>添加滑块内容：<input type="text" v-model="tabContent" class="itemcontent"></label><input type="button" value="添加选项" @click="addItem()" class="addbtn"><div class="tab"><ul><li v-for="(value, index) in tabs" v-bind:class="{active: index==num}" @mouseover="toggle(index)" @dblclick="del(index)">{{value}}</li></ul></div><div class="content"><div class="box" v-for="(value, index) in tabContents" v-show="index == num" contenteditable="true" @blur="editContent(index,value)">{{value+index}}</div></div></div></body><script src="js/vue.js"></script><script>var v = new Vue ({    el: "#tabPanel",    data: {tabs: ["第一项","第二项"],tabContents: ["第一项内容","第二项内容"],num: 0,tabItem:"",tabContent:""    },    methods:{//切换滑块toggle: function(index){this.num = index;},//添加滑块addItem: function(){if(this.tabItem == "" || this.tabContent == ""){  alert("填写完整的名称和内容");}else{  this.tabs.push(this.tabItem);  this.tabContents.push(this.tabContent);}},//双击删除滑块del: function(index){this.tabs.splice(index,1);this.tabContents.splice(index,1)},//编辑选项内容editContent: function(index,value){this.tabContents[index] = value;console.log(this.tabContents);}    }});</script></html>
