无法让 ng-bind-html 工作

Question

问题： 我正在尝试使用 ng-bind-html 但我在控制台上收到以下错误：

下面是我调用ngSanitize的控制器：

并使用以下文件：

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular-sanitize.js"></script>

在我的表单中，我执行以下操作以使用 ng-bind-html。因此，当我尝试查看结果时，它仍在渲染 & 而不是 &:

<div ng-bind-html="e.Specialty"></div>

以下是专长中发生的事情：

如有任何帮助，我们将不胜感激。

@lealceldeiro：这是我尝试在其中实施您的建议但不确定我将在何处添加它的控制器：

                .on('keydown', function () {
                    ol.hide();
                })
                .on('blur change', function () {
                    ol[$this.val().length ? 'hide' : 'show']();
                })
                .triggerHandler('blur');
          $(window).one("resize", function () { adjustToResizing(ol); });
        }
      });
    }
  });
})(jQuery);

jQuery(document).add(window).bind('ready load', function() {
  if (jQuery.placeholder) {
    jQuery.placeholder.shim();
  }
});

当您使用 ng-bind-html, AngularJS sometimes consider some contents as unsafe (as your case), so you need to use the $sce 服务以便 "mark" 此内容安全（使用）时，如下所示：

$sce.trustAsHtml("CLINICAL & SOCIAL");（见下面的演示）

来自$sanitize

The input is sanitized by parsing the HTML into tokens. All safe tokens (from a whitelist) are then serialized back to properly escaped html string. This means that no unsafe input can make it into the returned string.

在这种情况下，"unsafe" 部分是 &

angular
.module('app', [])
.controller('ctrl', ctrl);

function ctrl($scope, $sce) {
$scope.Specialty = $sce.trustAsHtml("CLINICAL &amp; SOCIAL");
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular-sanitize.js"></script>

<div ng-app="app" ng-controller="ctrl">

Specialty: <span ng-bind-html="Specialty"></span>

</div>
