我一生都无法弄清楚如何让角带弹出框在返回的 JSON 内容中工作（数据属性在 JSON 文件中）。

我想这就是你想要的。如果是这样，不客气:)

工作示例

基本上我做了两件事。我不喜欢将数据发送到 unsafe-html 的函数，更好的方法是通过它进行过滤器和管道日期.. 更好，因为您可以内联而不将它们发送到函数。我在您的 app.js 中将此过滤器称为“不安全”

app.filter('unsafe', function($sce) {
    return function(val) {
      return $sce.trustAsHtml(val);
    };
});

其次..就像上面在评论中提到的那样，仅仅因为您可以“渲染”它并不意味着它已被编译..因此您必须运行编译指令来重新处理渲染的 HTML 并将其转换为我们关心的代码。我称该指令为“编译模板”

app.directive('compileTemplate', function($compile, $parse){
 return {
link: function(scope, element, attr){
  var parsed = $parse(attr.ngBindHtml);
  function getStringValue() { return (parsed(scope) || '').toString(); }

        //Recompile if the template changes
        scope.$watch(getStringValue, function() {
            $compile(element, null, -9999)(scope);  //The -9999 makes it skip directives so that we do not recompile ourselves
          });
      }         
    }
  });

你会这样写你的“动态内容”：

    <!-- Dynamic Content -->
<div class="well">
  <h4>{{clickedContent.contentTitle}}</h4>
  <ul>
    <li ng-repeat="item in clickedContent.headlines" ng-bind-html="item.headline | unsafe" compile-template></li>
  </ul>
</div>

现在您可以看到该示例有效。

如果这有帮助，请给代表！谢谢！！！

您面临的问题是 AngularJS，为了您客户的安全，会自动清理ng-bind-html属性中的 HTML 输入。它会自动删除任何潜在的恶意属性，例如 JS 事件、数据前缀属性、id属性（可能是为了防止冲突......）和style.

该文档显示了如何绕过此自动清理。

在本质上：

  1. $scope在您的MainController.
  2. 用于$templateCache.trustAsHtml(<html>)返回原始 HTML。
  3. 在属性中调用该函数ng-bind-html来检索原始 HTML。

不幸的是，我对 AngularJS 不是很有经验，并且无法在您的示例中使用它。（我不知道如何将一个或多或少的动态变量传递给函数，我曾希望ng-bind-html=\"rawHtml(item.headline)\"会足够好，但事实并非如此。）

祝你好运！
