AngularJS 包含
在 AngularJS 中,你可以在 HTML 中包含 HTML 文件。
在 HTML 中包含 HTML 文件
在 HTML 中,目前还不支持包含 HTML 文件的功能。
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.html'"></div>
<div ng-include="'myUsers_Form.html'"></div>
</div>
</body>
步骤如下:
步骤 1: 创建 HTML 列表
myUsers_List.html
<h3>Users</h3>
<table class="table table-striped">
<thead><tr>
<th>Edit</th>
<th>FirstName</th>
<th>LastName</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>CreateNewUser
</button>
<hr>
<h3 ng-show="edit">CreateNewUser:</h3>
<h3 ng-hide="edit">EditUser:</h3>
<form class="form-horizontal">
<div class="form-group">
<label class="col-sm-2 control-label">FirstName:</label>
<div class="col-sm-10">
<input type="text" ng-model="fName" ng-disabled="!edit" placeholder="First Name">
</div>
</div>
<div class="form-group">
<label class="col-sm-2 control-label">LastName:</label>
<div class="col-sm-10">
<input type="text" ng-model="lName" ng-disabled="!edit" placeholder="Last Name">
</div>
</div>
<div class="form-group">
<label class="col-sm-2 control-label">Password:</label>
<div class="col-sm-10">
<input type="password" ng-model="passw1" placeholder="Password">
</div>
</div>
<div class="form-group">
<label class="col-sm-2 control-label">Repeat:</label>
<div class="col-sm-10">
<input type="password" ng-model="passw2" placeholder="Repeat Password">
</div>
</div>
</form>
<hr>
<button class="btn btn-success" ng-disabled="error || incomplete">
<span class="glyphicon glyphicon-save"></span>SaveChanges
</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>
<link rel="stylesheet" href ="http://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<body ng-app="myApp" ng-controller="userCtrl">
<div class="container">
<div ng-include="'myUsers_List.html'"></div>
<div ng-include="'myUsers_Form.html'"></div>
</div>
<script src="myUsers.js"></script>
</body>
</html>
结果:
