這篇文章主要介紹了AngularJS實(shí)現(xiàn)tab選項(xiàng)卡的方法,結(jié)合實(shí)例形式較為詳細(xì)的分析了AngularJS實(shí)現(xiàn)tab選項(xiàng)卡的原理、實(shí)現(xiàn)技巧與相關(guān)注意事項(xiàng),需要的朋友可以參考下

本文實(shí)例講述了AngularJS實(shí)現(xiàn)tab選項(xiàng)卡的方法。分享給大家供大家參考，具體如下：

一、代碼實(shí)現(xiàn)

<!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'>許嵩</li>
        <li ng-class='{active:activeTab==2}' ng-click='activeTab=2'>周杰倫</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'>陳奕迅</li>
      </ul>
      <div class="TabCon">
        <div ng-show='activeTab==1'>斷橋殘雪、千百度、幻聽(tīng)、想象之中</div>
        <div ng-show='activeTab==2'>紅塵客棧、牛仔很忙、給我一首歌的時(shí)間、聽(tīng)媽媽的話</div>
        <div ng-show='activeTab==3'>被風(fēng)吹過(guò)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、效果預(yù)覽

三、實(shí)現(xiàn)原理

選項(xiàng)卡的內(nèi)容是顯示還是隱藏是由activeTab的值決定的，而這個(gè)值是通過(guò)選項(xiàng)卡上面的ng-click指令設(shè)置的，當(dāng)對(duì)應(yīng)選項(xiàng)卡的內(nèi)容顯示的時(shí)候，給點(diǎn)擊的按鈕添加樣式，這樣做雖然也能實(shí)現(xiàn)選項(xiàng)卡的內(nèi)容，但是這樣做的的弊端是，選項(xiàng)卡的內(nèi)容是固定的，不好去改變，所以接下來(lái)我們將上面的代碼改成下面這種形式

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){
      $scope.vm=[
        {"list":"許嵩","con":"斷橋殘雪、千百度、幻聽(tīng)、想象之中"},
        {"list":"周杰倫","con":"紅塵客棧、牛仔很忙、給我一首歌的時(shí)間、聽(tīng)媽媽的話"},
        {"list":"林俊杰","con":"被風(fēng)吹過(guò)的夏天、江南、一千年以后"},
        {"list":"陳奕迅","con":"十年、K歌之王、浮夸"}
      ];
      var selected=$scope.selected;
      $scope.show=function(index){
        $scope.selected=index;
      };
    });
  </script>
</html>

說(shuō)明：vm這個(gè)數(shù)組里面是我們自己定義的一些假數(shù)據(jù)（這個(gè)數(shù)據(jù)實(shí)際上是可以從后臺(tái)獲取的），然后我們通過(guò)ng-repeat指令循環(huán)遍歷出vm里面的數(shù)據(jù)，插入到頁(yè)面中，$index是每個(gè)內(nèi)容對(duì)象的索引值
