ng-bind-html 的使用

AngualrJS 提供了指令ng-bind-html 用於綁定包含HTML標簽的文檔，使用方式：

<ANY
  ng-bind-html="">
...
</ANY>

測試案例：

index.html

<div ng-controller="TestCtrl">
            <div>
                <p ng-bind-html="myHTML"></p>
            </div>
</div>

index.js

var myApp = angular.module('myApp', []);

myApp.controller('TestCtrl', ['$scope', function($scope){
        $scope.myHTML = '<strong>Hot</strong>';
}]);

瀏覽器輸出下面錯誤:

查閱官方文檔要使用：$sanitize服務

Note: If a $sanitize service is unavailable and the bound value isn't explicitly trusted, you will have an exception (instead of an exploit.)

在angular.module中配置sanitize服務：

var myApp = angular.module('myApp', ['ngSanitize']);

再次刷新瀏覽器，輸出以下錯誤信息：

 Uncaught Error: [$injector:modulerr] Failed to instantiate module myApp due to:
Error: [$injector:modulerr] Failed to instantiate module ngSanitize due to:
Error: [$injector:nomod] Module 'ngSanitize' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

發現angular.js沒有sanitize模塊，在這里將

angular-sanitize.js加載進來就可以了。

<script src="../js/angular-sanitize.js"></script>
