HTML编码的字符串在AngularJS中无法正确翻译

问题描述：

我有一个这样的HTML编码字符串:

I have an HTML encoded string like this:

Sign up and get &lt;span class=&quot;strong&quot;&gt;Something for     FREE!&lt;/span&gt;

当我在模板中使用ngSanitize和ng-bind-html时，如下所示:

When I use ngSanitize and ng-bind-html in my template like this:

<p ng-bind-html="someText"></p>

我取回HTML解码的字符串:

I get back the HTML decoded string:

Sign up and get <span class="strong">Something for Free!</span>

但是它实际上是在浏览器中显示HTML解码的字符串，而不是正确呈现HTML.

But it literally shows the HTML decoded string in browser, instead of rendering the HTML correctly.

如何让它在DOM中呈现正确的HTML?

How can I have it render the correct HTML in the DOM?

答

您可以先解码html字符串.这是一个有效的 plunker 示例.

You can decode the html string first. Here's a working plunker example.

angular.module('app', ['ngSanitize'])
  .controller('ctrl', ['$scope', '$sanitize', function($scope, $sanitize){
    $scope.someText = htmlDecode("Sign up and get &lt;span class=&quot;strong&quot;&gt;Something for     FREE!&lt;/span&gt;");

    function htmlDecode(input){ 
      var e = document.createElement('div');
      e.innerHTML = input;
      return e.childNodes.length === 0 ? "" : e.childNodes[0].nodeValue;
    }
}]);
