我们可以用$ sce.trustAsHtml（串）出＆QUOT;滤波器QUOT; S？

问题描述

HTML

<div ng-app="app">
  <test-d class="my-class">this should be replaced</test-d>
</div>

JS：

    angular.module('app', []).directive('testD', ['$compile','$sce', function($compile, $sce) {
        return {
            restrict: 'E',
            link: function(scope, element, attrs, controller) {

                //"case 1"
                //var testElement = angular.element('<div class="{{testClass}}"><div ng-repeat="item in items">{{item.n}}.{{item.label}}</div></div>');

                //"case 2"
                var testElement = angular.element('<div class="{{testClass}}"><div ng-repeat="item in items">{{item.n}}<div class="how-to-remove-this-div" ng-bind-html="item.label|htmlize"></div></div></div>');

                scope.testClass = attrs.class;

                scope.items = [
                    //{n:10,label:$sce.trustAsHtml('<span class="with-icon">label 11</span>')},
                    // "case 1" of "testElement": no any effects (with "case 1" that would be preferred)
                    // "case 2" of "testElement": Error: [$sce:itype] Attempted to trust a non-string value in a content requiring a string: Context: html

                    {n:20,label:'<span class="with-icon">label 22</span>'},
                    {n:30,label:'<span class="with-icon">label 33</span>'}
                ];

                var testElementCompiled = $compile(testElement)(scope);

                //"case 3"
                element.replaceWith(testElementCompiled);

                //"case 4"
                //element.replaceWith($sce.trustAsHtml(testElementCompiled));
            }
        }
}]).filter('htmlize', ['$sce', function($sce){
        return function(val) {
            return $sce.trustAsHtml(val);
        };
}]);

的jsfiddle：

问题：
1）是有可能使用trustAsHtml出滤波器上下文的？
2）如果没有如何获得使用NG绑定HTML的指令的情况下，以如何做 - 删除 - 这-DIV阶级摆脱的div？

Questions: 1) is it possible to use trustAsHtml out of filter context ?2) IF NOT how to get rid of div with "how-to-remove-this-div" class in case of using "ng-bind-html" directive ?

推荐答案

得到它（trustAsHtml）的指令这里。在错误：[$ SCE：ITYPE]尝试在需要字符串内容信任一个非字符串值：上下文背景：HTML时，我错误地尝试在发生错误相同的标签上呼吁trustAsHtml两次。

Got it (trustAsHtml) working in directive here. The "Error: [$sce:itype] Attempted to trust a non-string value in a content requiring a string: Context: html" error was occured when i by mistake try to call trustAsHtml twice on the same "label".

问题的第二部分仍然存在，但我会用一些变通办法解决它。不管怎样，这很有趣，以解决它。

Second part of question still remains, but i will solve it with some workarounds. And anyway, it's interesting to resolve it too.
