【17】AngularJS Bootstrap
AngularJS Bootstrap
AngularJS 的首选样式表是 Twitter Bootstrap, Twitter Bootstrap 是目前最受欢迎的前端框架。
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/3.2.0/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/3.2.0/css/bootstrap.min.css">
以下是一个完整的 HTML 实例, 使用了 AngularJS 指令和 Bootstrap 类。

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 | 如果每个字段都为空(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 |
结果:
