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
希望本文所述对大家AngularJS程序设计有所帮助。
