AngularJs $scope function and Filter 异同

首先我们看这样一个实例：

// Filter
sl.filter('titleFilter', function() {
    return function(title, id) {
      var url = '/public/article#/' + id;
      return '<a href="' + url + '">' + title + '</a>';
    };
  });

 

使用实例：(Works good)

<h6 class="news-title" ng-bind="v.title | titleFilter:v.id"></h6>

 

另一实例：（Html插入, It doesn't work, WHY?）

$scope.getHtml = function (html) {
      return $sce.trustAsHtml(html);
    };

 

<h6 class="news-title" ng-bind-html="getHtml(v.title | titleFilter:v.id))"></h6>

 

转换思路：

// Controller $scope function
$scope.getTitle = function(title, id) {
      var url = '/public/article#/' + id;
      return '<a href="' + url + '">' + title + '</a>';
    }

 (Work perfect)

<h6 class="news-title" ng-bind-html="getHtml(getTitle(v.title, v.id))"></h6>
