AngularJS 之包含

在 AngularJS 中，你可以在 HTML 中包含 HTML 文件。

服务端包含

大多服务端脚本都支持包含文件功能 (SSI： Server Side Includes)。
使用 SSI, 你可在 HTML 中包含 HTML 文件，并发送到客户端浏览器。

<?php require("navigation.php"); ?>

客户端包含

通过 JavaScript 有很多种方式可以在 HTML 中包含 HTML 文件。
通常我们使用 http 请求 (AJAX) 从服务端获取数据，返回的数据我们可以通过 使用 innerHTML 写入到 HTML 元素中。

AngularJS 包含

使用 AngularJS, 你可以使用 ng-include 指令来包含 HTML 内容:

<body>
    <div class="container">
        <div ng-include="'myUsers_List.htm'"></div>
        <div ng-include="'myUsers_Form.htm'"></div>
    </div>
</body>

步骤如下：

  • 步骤 1: 创建 HTML 列表
    myUsers_List.html

    <h3>用户</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>  Edit
                </button>
            </td>
            <td>{{ user.fName }}</td>
            <td>{{ user.lName }}</td>
        </tr>
    </tbody>
</table>

  • 步骤 2: 创建 HTML 表单
    myUsers_Form.html

    <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>保存
</button>

  • 步骤 3: 创建控制器
    myUsers.js

    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 &amp;&amp; (!$scope.fName.length ||
        !$scope.lName.length ||
        !$scope.passw1.length || !$scope.passw2.length)) {
        $scope.incomplete = true;
        }
    };
})

  • 步骤 4: 创建主页
    myUsers.html

    <!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <link rel="stylesheet" href="//apps.bdimg.com/libs/bootstrap/3.3.4/css/bootstrap.min.css">
    <script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script>
</head>
<body ng-app="myApp" ng-controller="userCtrl">
    <div class="container">
        <div ng-include="'myUsers_List.htm'"></div>
        <div ng-include="'myUsers_Form.htm'"></div>
    </div>
    <script src= "myUsers.js"></script>
</body>
</html>
