5、AngularJS 直接绑定显示html （$sce、$sanitize服务）

1、直接使用$sce服务(angularjs中：$sce.trustAsHtml($scope.snippet)。html：ng-bind-html="snippet")

以下代码输出：

 1 <div ng-bind-html="snippet"></div>
 2 
 3 <script>
 4 　　angular.module('sanitizeExample', [])
 5 　　.controller('ExampleController', ['$scope', '$sce', function($scope, $sce) {
 6 　　　　　　　　//测试用字符串
 7              $scope.snippet =
 8                '<p style="color:blue">an html\n' +
 9                '<em onmouseover="this.textContent=\'PWN3D!\'">click here</em>\n' +
10                'snippet</p>';
11 　　　　　　　　//$sce 服务trustAsHtml 进行编译
12              $scope.deliberatelyTrustDangerousSnippet = function() {
13                return $sce.trustAsHtml($scope.snippet);
14              };
15      }]);
16 </script>

 

 2、使用angular-sanitize.js 模块中的$sanitize服务，信任字符串，直接显示html

以下代码输出：

 1 <div ng-bind-html="snippet"></div>
 2 
 3 <script>
 4 　　angular.module('sanitizeExample', ['ngSanitize'])
 5 　　.controller('ExampleController', ['$scope', function($scope) {
 6 　　　　　　　　//测试用字符串
 7              $scope.snippet =
 8                '<p style="color:blue">an html\n' +
 9                '<em onmouseover="this.textContent=\'PWN3D!\'">click here</em>\n' +
10                'snippet</p>';
11      }]);
12 </script>

 

3、整体demo代码：

 1 <!DOCTYPE html>
 2 <html lang="en">
 3 <head>
 4     <meta charset="UTF-8">
 5     <meta name="viewport" content="width=device-width, initial-scale=1.0">
 6     <meta http-equiv="X-UA-Compatible" content="ie=edge">
 7     <title>Document</title>
 8 </head>
 9 <body ng-app="sanitizeExample">
10     <div ng-controller="ExampleController">
11         Snippet: <textarea ng-model="snippet" cols="60" rows="3"></textarea>
12        <table>
13          <tr>
14            <td>Directive</td>
15            <td>How</td>
16            <td>Source</td>
17            <td>Rendered</td>
18          </tr>
19          <tr id="bind-html-with-sanitize">
20            <td>ng-bind-html</td>
21            <td>Automatically uses $sanitize</td>
22            <td><pre>&lt;div ng-bind-html="snippet"&gt;<br/>&lt;/div&gt;</pre></td>
23            <td><div ng-bind-html="snippet"></div></td>
24          </tr>
25          <tr id="bind-html-with-trust">
26            <td>ng-bind-html</td>
27            <td>Bypass $sanitize by explicitly trusting the dangerous value</td>
28            <td>
29            <pre>&lt;div ng-bind-html="deliberatelyTrustDangerousSnippet()"&gt;&lt;/div&gt;</pre>
30            </td>
31            <td><div ng-bind-html="deliberatelyTrustDangerousSnippet()"></div></td>
32          </tr>
33          <tr id="bind-default">
34            <td>ng-bind</td>
35            <td>Automatically escapes</td>
36            <td><pre>&lt;div ng-bind="snippet"&gt;<br/>&lt;/div&gt;</pre></td>
37            <td><div ng-bind="snippet"></div></td>
38          </tr>
39        </table>
40        </div>
41 <script>
42 angular.module('sanitizeExample', ['ngSanitize'])
43            .controller('ExampleController', ['$scope', '$sce', function($scope, $sce) {
44              $scope.snippet =
45                '<p style="color:blue">an html\n' +
46                '<em onmouseover="this.textContent=\'PWN3D!\'">click here</em>\n' +
47                'snippet</p>';
48              $scope.deliberatelyTrustDangerousSnippet = function() {
49                return $sce.trustAsHtml($scope.snippet);
50              };
51            }]);
52 </script>
53 </body>
54 //修改为本地angular.js 相对地址
55 <script src="angular.min.js" type="text/javascript"></script>
56 <script src="angular-sanitize.js" type="text/javascript"></script>
57 </html>
