本文实例讲述了AngularJS实现tab选项卡的方法。分享给大家供大家参考，具体如下：

一、代码实现


<!DOCTYPE html>
<html ng-app='app'>
 <head>
 <meta charset="UTF-8">
 <title></title>
 <style>
 *{
 list-style: none;
 margin: 0;
 padding: 0;
 }
 .TabNav{
 height: 131px;
 width: 450px;
 position: relative;
 margin-left: auto;
 margin-right: auto;
 margin-top: 100px;
 }
 .TabNav ul li{
 float: left;
 background: -webkit-gradient(linear,left top,left bottom, from(#fefefe), to(#ededed));
 border: 1px solid #ccc;
 padding: 5px 0;
 width: 100px;
 text-align: center;
 margin-left: -1px;
 position: relative;
 cursor: pointer;
 }
 .TabCon{
 position: absolute;
 left: -1px;
 top: 30px;
 border: 1px solid #ccc;
 border-top: none;
 width: 403px;
 height: 100px;
 }
 .TabNav ul li.active{
 background: #FFFFFF;
 border-bottom: none;
 }
 </style>
 <script src="js/angular.min.js" type="text/javascript" charset="utf-8"></script>
 </head>
 <body>
 <div class="TabNav">
 <ul ng-init='activeTab=1'>
 <li ng-class='{active:activeTab==1}' ng-click='activeTab=1'>许嵩</li>
 <li ng-class='{active:activeTab==2}' ng-click='activeTab=2'>周杰伦</li>
 <li ng-class='{active:activeTab==3}' ng-click='activeTab=3'>林俊杰</li>
 <li ng-class='{active:activeTab==4}' ng-click='activeTab=4'>陈奕迅</li>
 </ul>
 <div class="TabCon">
 <div ng-show='activeTab==1'>断桥残雪、千百度、幻听、想象之中</div>
 <div ng-show='activeTab==2'>红尘客栈、牛仔很忙、给我一首歌的时间、听妈妈的话</div>
 <div ng-show='activeTab==3'>被风吹过的夏天、江南、一千年以后</div>
 <div ng-show='activeTab==4'>十年、K歌之王、浮夸</div>
 </div>
 </div>
 </body>
 <script type="text/javascript">
 var app=angular.module('app',[]);
 app.controller('tabcontroller',function($scope){
 var vm=$scope.vm;
 });
 </script>
</html>

二、效果预览

三、实现原理

选项卡的内容是显示还是隐藏是由activeTab的值决定的，而这个值是通过选项卡上面的ng-click指令设置的，当对应选项卡的内容显示的时候，给点击的按钮添加样式，这样做虽然也能实现选项卡的内容，但是这样做的的弊端是，选项卡的内容是固定的，不好去改变，所以接下来我们将上面的代码改成下面这种形式

四、改版


<!DOCTYPE html>
<html ng-app='app'>
 <head>
 <meta charset="UTF-8">
 <title></title>
 <style>
 *{
 list-style: none;
 margin: 0;
 padding: 0;
 }
 .TabNav{
 height: 131px;
 position: relative;
 margin-left: 100px;
 margin-top: 100px;
 }
 .TabNav ul li{
 float: left;
 background: -webkit-gradient(linear,left top,left bottom, from(#fefefe), to(#ededed));
 border: 1px solid #ccc;
 padding: 5px 0;
 width: 100px;
 text-align: center;
 margin-left: -1px;
 position: relative;
 cursor: pointer;
 }
 .TabCon{
 position: absolute;
 left: -1px;
 top: 30px;
 border: 1px solid #ccc;
 border-top: none;
 width: 403px;
 height: 100px;
 }
 .TabNav ul li.active{
 background: #FFFFFF;
 border-bottom: none;
 }
 </style>
 <script src="js/angular.min.js" type="text/javascript" charset="utf-8"></script>
 </head>
 <body>
 <div class="TabNav" ng-controller='tabcontroller'>
 <ul ng-init='selected=0'>
 <li ng-class='{active:selected==$index}' ng-click='show($index)' ng-repeat='item in vm'>{{item.list}}</li>
 </ul>
 <div class="TabCon">
 <div ng-show='selected==$index' ng-repeat='item in vm'>{{item.con}}</div>
 </div>
 </div>
 </body>
 <script type="text/javascript">
 var app=angular.module('app',[]);
 app.controller('tabcontroller',function($scope){
 $scope.vm=[
 {"list":"许嵩","con":"断桥残雪、千百度、幻听、想象之中"},
 {"list":"周杰伦","con":"红尘客栈、牛仔很忙、给我一首歌的时间、听妈妈的话"},
 {"list":"林俊杰","con":"被风吹过的夏天、江南、一千年以后"},
 {"list":"陈奕迅","con":"十年、K歌之王、浮夸"}
 ];
 var selected=$scope.selected;
 $scope.show=function(index){
 $scope.selected=index;
 };
 });
 </script>
</html>

说明：vm这个数组里面是我们自己定义的一些假数据（这个数据实际上是可以从后台获取的），然后我们通过ng-repeat指令循环遍历出vm里面的数据，插入到页面中，$index是每个内容对象的索引值
