AngularJS 包含

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>&nbsp;&nbsp;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 && (!$scope.fName.length ||
                !$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>
