这里用到AngularJS四大特性之二----双向数据绑定
注意：没写一行DOM代码！这就是ng的优点，bootstrap.css为了布局，JS代码也只是简单创建ng模块和ng控制器
效果：
<!DOCTYPE html>
<html lang="en" ng-app="myModule5"><!--3、ng-app="myModule5"启动ng并调用模块-->
<head>
<meta charset="UTF-8">
<link rel="stylesheet" href="css/bootstrap.css">
<title>全选/取消全选</title>
</head>
<body>
<div class="container" ng-controller="myCtrl5"><!--4、ng-controller="myCtrl5"启用控制器-->
<h2>全选和取消全选</h2>
<table class="table table-bordered">
<thead>
<tr>
<th>选择</th>
<th>姓名</th>
<th>操作</th>
</tr>
</thead>
<tbody>
<tr>
<td>
<input ng-checked="selectAll" type="checkbox">
</td>
<td>Tom</td>
<td>
<button class="btn btn-danger btn-xs">删除</button>
</td>
</tr>
<tr>
<td>
<input ng-checked="selectAll" type="checkbox">
</td>
<td>Mary</td>
<td>
<button class="btn btn-danger btn-xs">删除</button>
</td>
</tr>
<tr>
<td>
<input ng-checked="selectAll" type="checkbox">
</td>
<td>King</td>
<td>
<button class="btn btn-danger btn-xs">删除</button>
</td>
</tr> </tbody>
</table> <input type="checkbox" ng-model="selectAll">
<span ng-hide="selectAll">全选</span>
<span ng-show="selectAll">取消全选</span>
</div>
<script src="js/angular.js"></script><!--1、引入angularJS-->
<script>
//2、创建自定义模块和控制器
angular.module('myModule5', ['ng']).
controller('myCtrl5', function($scope){ });
</script>
</body>
</html>
