Bootstrap

你可以在你的 AngularJS 应用中加入 Twitter Bootstrap,你可以在你的 <head>元素中添加如下代码:

<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.4/css/bootstrap.min.css">

如果站点在国内,建议使用百度静态资源库的Bootstrap,代码如下:

<link rel="stylesheet" href="//apps.bdimg.com/libs/bootstrap/3.3.4/css/bootstrap.min.css">

以下是一个完整的 HTML 实例, 使用了 AngularJS 指令和 Bootstrap 类。

<tr ng-repeat 循环 users 对象数组,每个 user 对象放在 <tr> 元素中。
<button ng-click 当点击 <button> 元素时调用函数 editUser()
<h3 ng-show 如果 edit = true 显示 <h3> 元素
<h3 ng-hide 如果 edit = true 隐藏 <h3> 元素
<input ng-model 为应用程序绑定 <input> 元素
<button ng-disabled 如果发生错误或者 incomplete = true 禁用 <button> 元素

JavaScript 代码解析

Scope 属性 用途
$scope.fName 模型变量 (用户名)
$scope.lName 模型变量 (用户姓)
$scope.passw1 模型变量 (用户密码 1)
$scope.passw2 模型变量 (用户密码 2)
$scope.users 模型变量 (用户的数组)
$scope.edit 当用户点击创建用户时设置为true。
$scope.error 如果 passw1 不等于 passw2 设置为 true
$scope.incomplete 如果有一个字段为空(length = 0)设置为 true
$scope.editUser 设置模型变量
$scope.watch 监控模型变量
$scope.test 验证模型变量的错误和完整性
