Jquery 触发事件两次的角度指令

我正在创建一个滑入指令来显示一些选项。标题中有3个按钮，即“后退”、“取消全部”和“应用”。现在，当我单击任何按钮时，“单击”事件将触发两次。请看下面的代码

HTML:

我已经成功地解决了这个问题。回答我的问题以帮助某人：

更新指令代码：

angular.module('MyAppObj')
.directive('searchFilter', [function () {
    function link(scope, element, attrs){
        $(document).on('click','#searchFilterBtn.search-filter-btn',function(e){
              e.stopPropagation();
              $(element).removeClass('ng-hide');
              setTimeout(function () { $(element).addClass('slide-in'); }, 200);
          });

          $(document).on('click','#searchFiltersAction #searchFilterBackBtn',function(e){
              e.stopPropagation();
              console.log('Closing the open filters view...',e.target.tagName)
              $(element).removeClass('slide-in');
              setTimeout(function () { $(element).addClass('ng-hide'); }, 500);
          });

          $(document).on('click','#searchFiltersAction #deselectAllFilters',function(e){
              e.stopPropagation();
              console.log('Deselect all selected filters...')
          });

          $(document).on('click','#searchFiltersAction #applyFiltersBtn',function(e){
              e.stopPropagation();
              console.log('Apply selected filters to the search results...')
          });

          var cleanup = function(){
            $(document).off('click','#searchFilterBtn.search-filter-btn');
            $(document).off('click','#searchFiltersAction #searchFilterBackBtn');
            $(document).off('click','#searchFiltersAction #deselectAllFilters');
            $(document).off('click','#searchFiltersAction #applyFiltersBtn');
          }

          scope.$on('$destroy',cleanup)
    }
  return {
      restrict: 'CA',
      link: link
  };
 }]);

你确定你没有两次使用指令吗？如果您在link方法的第一行上放置断点，它是否会被命中两次？因为您将所有这些都附加到文档中，所以每当您将此指令加载到应用程序中时，这些事件都会被反弹。这段HTML代码是否隐藏在某种ng if后面？如果是这样，每次ng If求值为true时，所有这些都将绑定一个新事件。@BillBergquist-您已经正确地猜测了问题的根本原因。但现在的问题是如何处理这种情况？因为我必须使用指令。。。

angular.module('MyAppObj')
.directive('searchFilter', [function () {
  return {
      restrict: 'CA',
      link: function (scope, element, attrs) {
          $(document).on('click','#searchFilterBtn.search-filter-btn',function(e){
              e.stopPropagation();
              $(element).removeClass('ng-hide');
              setTimeout(function () { $(element).addClass('slide-in'); }, 200);
          });

          $(document).on('click','#searchFiltersAction #searchFilterBackBtn',function(e){
              e.stopPropagation();
              console.log('Closing the open filters view...',e.target.tagName)
              $(element).removeClass('slide-in');
              setTimeout(function () { $(element).addClass('ng-hide'); }, 500);
          });

          $(document).on('click','#searchFiltersAction #deselectAllFilters',function(e){
              e.stopPropagation();
              console.log('Deselect all selected filters...')
          });

          $(document).on('click','#searchFiltersAction #applyFiltersBtn',function(e){
              e.stopPropagation();
              console.log('Apply selected filters to the search results...')
          });
      }
  };
}]);

              $(element).removeClass('ng-hide');

          });
