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。

查看 Bootstrap教程。


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。

JavaScript 代码

myUsers.js

 
angular.module('myApp', []).controller('userCtrl', function($scope) {
$scope.fName = '';
$scope.lName = '';
$scope.passw1 = '';
$scope.passw2 = '';
$scope.users = [

{id:4, fName:'Jack', lName:"Jones" },
{id:5, fName:'John', lName:"Doe" },
{id:6, fName:'Peter',lName:"Pan" }
];
$scope.edit = true;
$scope.error = false;
$scope.incomplete = false;

$scope.editUser = function(id) {
  if (id == 'new') {
    $scope.edit = true;
    $scope.incomplete = true;
    $scope.fName = '';
    $scope.lName = '';
    } else {
    $scope.edit = false;
    $scope.fName = $scope.users[id-1].fName;
    $scope.lName = $scope.users[id-1].lName;

$scope.$watch('passw1',function() {$scope.test();});
$scope.$watch('passw2',function() {$scope.test();});
$scope.$watch('fName', function() {$scope.test();});
$scope.$watch('lName', function() {$scope.test();});

$scope.test = function() {

  }
  $scope.incomplete = false;

});
 

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
