带有 ng-repeat 和 ng-bind-html 的手风琴不起作用 [英] accordion with ng-repeat and ng-bind-html won't work

问题描述

我正在尝试以这种方式使用手风琴和 html 内容:

I'm trying to use accordion and html content in this way:

<accordion>
   <accordion-group ng-repeat="item in items">
      <accordion-heading>
          <a class="btn btn-primary btn-block btn-elenco">
         <img postsrc="img/flag/flag_{{item.index}}.jpg">
      </a>
      </accordion-heading>
      <p ng-bind-html="item.content"></p>
   </accordion-group>
</accordion>

和

var items = [];
for(var i=0;i<10;i++){
var content = "<div>TEST</div>";
items.push({index:i,content:content});
}
$scope.items = items;

var app = angular.module('MyApp',['ngSanitize','ui.bootstrap']);

Accordion 可以工作，但 html 不会渲染到 p 标签中.

Accordion works but html isn't rendered into p tag.

可能是什么问题?

编辑

如果我尝试以下操作:

<div ng-bind-html="to_trusted(item.content)"></div>

并向控制器添加函数:

$scope.to_trusted = function(html_code)
    {
    console.log(html_code);
    return $sce.trustAsHtml(html_code);
    }

没有任何变化，在控制台中我得到了许多未定义"！

Nothing changes and in console i get many "undefined"!

推荐答案

这是因为 HTML 内容被 Angular 声明为不安全的，因为它是 严格的上下文转义.

This is because the HTML content is declared unsafe by Angular due to it's Strict Contextual Escaping.

另一个 SO 答案已经清楚地解释了如何解决这个问题:HTML 注入，也就是说，如果您使用的是 Angular 版本1.2.0 或更高版本.

Another SO answer already explains clearly how this can be solved: HTML injection, that is if you are using Angular version 1.2.0 or up.
