今天我们学下AngularJS 结合 Bootstrap的应用。
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/3.3.4/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。
HTML 代码:
<!DOCTYPE html> <html> <head> <title>AngularJS 实例 | Web176教程网web176.com</title> <meta charset="utf-8"> <link rel="stylesheet" href="//apps.bdimg.com/libs/bootstrap/3.3.4/css/bootstrap.min.css"> <script src="https://cdn.staticfile.org/angular.js/1.4.6/angular.min.js"></script> </head> <body ng-app="myApp" ng-controller="userCtrl"> <div class="container"> <h3>Users</h3> <table class="table table-striped"> <thead> <tr> <th>编辑</th> <th>名</th> <th>姓</th> </tr> </thead> <tbody> <tr ng-repeat="user in users"> <td> <button class="btn" ng-click="editUser(user.id)"> <span class="glyphicon glyphicon-pencil"></span>编辑 </button> </td> <td>{{ user.fName }}</td> <td>{{ user.lName }}</td> </tr> </tbody> </table> <hr> <button class="btn btn-success" ng-click="editUser('new')"> <span class="glyphicon glyphicon-user"></span>创建新用户 </button> <hr> <h3 ng-show="edit">创建新用户:</h3> <h3 ng-hide="edit">编辑用户:</h3> <form class="form-horizontal"> <div class="form-group"> <label class="col-sm-2 control-label">名:</label> <div class="col-sm-10"> <input type="text" ng-model="fName" ng-disabled="!edit" placeholder="名"> </div> </div> <div class="form-group"> <label class="col-sm-2 control-label">姓:</label> <div class="col-sm-10"> <input type="text" ng-model="lName" ng-disabled="!edit" placeholder="姓"> </div> </div> <div class="form-group"> <label class="col-sm-2 control-label">密码:</label> <div class="col-sm-10"> <input type="password" ng-model="passw1" placeholder="密码"> </div> </div> <div class="form-group"> <label class="col-sm-2 control-label">重复密码:</label> <div class="col-sm-10"> <input type="password" ng-model="passw2" placeholder="重复密码"> </div> </div> </form> <hr> <button class="btn btn-success" ng-disabled="error || incomplete"> <span class="glyphicon glyphicon-save"></span>修改 </button> </div> <script> angular.module('myApp', []).controller('userCtrl', function($scope) { $scope.fName = ''; $scope.lName = ''; $scope.passw1 = ''; $scope.passw2 = ''; $scope.users = [ {id:1, fName:'Hege',lName:"Pege" }, {id:2, fName:'Kim',lName:"Pim" }, {id:3, fName:'Sal',lName:"Smith" }, {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();}); $scope.test = function() { if ($scope.passw1 !== $scope.passw2) { $scope.error = true; } else { $scope.error = false; } $scope.incomplete = false; if ($scope.edit && (!$scope.fName.length || !$scope.lName.length || !$scope.passw1.length || !$scope.passw2.length)) { $scope.incomplete = true; } }; }) </script> </body> </html>
指令解析
AngularJS 指令 | 描述 |
---|---|
<html ng-app | 为 <html> 元素定义一个应用(未命名) |

JavaScript 代码
//myUsers.js
angular.module('myApp', []).controller('userCtrl', function($scope) {
$scope.fName = '';
$scope.lName = '';
$scope.passw1 = '';
$scope.passw2 = '';

} else {

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 |
