角：NG-绑定-HTML过滤掉NG-点击？ [英] Angular: ng-bind-html filters out ng-click?

问题描述

我有我从JSON文件中加载一些HTML数据。

I have some html data that I'm loading in from a json file.

我在我的应用程序使用ngSanitize并采用NG-绑定-HTML显示该HTML数据。

I am displaying this html data by using ngSanitize in my app and using ng-bind-html.

现在，我想在JSON BLOB的任何链接转换标准

Now I would like to convert any links in the json blob from the standard

• ＆LT; A HREF =some_link＆GT;链接＆LT; / A＆GT;

• <a href="some_link">link</a>

到

• ＆LT;一个NG点击=GotoLink（'some_link'，'_系统'）＆GT;链接＆LT; / A＆GT;

• <a ng-click="GotoLink('some_link','_system')">link</a>.

所以我做的JSON文件中的一些正则表达式的链接转换，但由于某些原因，但是NG-绑定，HTML是过滤掉NG单击它的输出，我想不通为什么。难道应该这样做，如果是的话是有可能禁用这种行为？

So I'm doing some regExp on the json file to convert the links, but for some reason however ng-bind-html is filtering out the ng-click in it's output, and I can't figure out why. Is it supposed to do this, and if so is it possible to disable this behavior?

看看这个对的jsfiddle演示：

任何想法？

推荐答案

好了，问题是，它是不是您编译包含HTML（角度不解析它找到指令和诸如此类的东西）。不能想办法让它从控制器中编译，但你可以创建一个指令，它包括的内容，并对其进行编译。

Ok, so the issue is that it isn't compiling the html you include (angular isn't parsing it to find directives and whatnot). Can't think of a way to make it to compile from within the controller, but you could create a directive that includes the content, and compiles it.

所以，你会改变

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

到

<p compile="name"></p>

和则对于JS：

var myApp = angular.module('myApp', ['ngSanitize']);
angular.module('myApp')
.directive('compile', ['$compile', function ($compile) {
  return function(scope, element, attrs) {
    scope.$watch(
      function(scope) {
        return scope.$eval(attrs.compile);
      },
      function(value) {
        element.html(value);
        $compile(element.contents())(scope);
      }
   )};
  }]).controller('MyCtrl', function($scope) {
    var str = 'hello http://www.cnn.com';
    var urlRegEx = /((([A-Za-z]{3,9}:(?:\/\/)?)(?:[\-;:&=\+\$,\w]+@)?[A-Za-z0-9\.\-]+|(?:www\.|[\-;:&=\+\$,\w]+@)[A-Za-z0-9\.\-]+)((?:\/[\+~%\/\.\w\-]*)?\??(?:[\-\+=&;%@\.\w]*)#?(?:[\.\!\/\\\w]*))?)/g;
    result = str.replace(urlRegEx, "<a ng-click=\"GotoLink('$1',\'_system\')\">$1</a>");
    $scope.GotoLink = function() { alert(); }
    $scope.name = result;
});

角1.4.3： http://jsfiddle.net/5g6z58yy/ （同一code和以前一样，但有些人说这不会对1.4工作。*）
