推荐答案

您可以创建过滤器，将净化你的HTML。

You can create filter which will sanitize your html.

我用它用strip_tags功能
http://phpjs.org/functions/strip_tags/

I used in it strip_tags function http://phpjs.org/functions/strip_tags/

angular.module('filters', []).factory('truncate', function () {
    return function strip_tags(input, allowed) {
      allowed = (((allowed || '') + '')
        .toLowerCase()
        .match(/<[a-z][a-z0-9]*>/g) || [])
        .join(''); // making sure the allowed arg is a string containing only tags in lowercase (<a><b><c>)
      var tags = /<\/?([a-z][a-z0-9]*)\b[^>]*>/gi,
        commentsAndPhpTags = /<!--[\s\S]*?-->|<\?(?:php)?[\s\S]*?\?>/gi;
      return input.replace(commentsAndPhpTags, '')
        .replace(tags, function($0, $1) {
          return allowed.indexOf('<' + $1.toLowerCase() + '>') > -1 ? $0 : '';
        });
    }
});

控制器：

angular.module('myApp', ['filters'])
.controller('IndexController', ['$scope', 'truncate', '$sce', function($scope, truncate, $sce){
  $scope.text="";

  $scope.$watch('text', function(){
    $scope.sanitized = $sce.trustAsHtml(truncate($scope.text, '<a><br>'));
  });
}]);

查看：

<div ng-bind-html="sanitized"></div>
