有些需求中,需要一个元素上既有双击事件,也有单击事件,而两者实现的效果不一样。
这时可以使用ng-dblclick与ng-click来实现需求,但是要避免浏览器将双击事件误认为是两次单击事件,从而出现逻辑错误。
可以通过$timeout进行判断,取消第二次单击事件的执行。
<img src="myImage.jpg" ng-click="singleClick()" ng-dblclick="doubleClick()"> In your controller the singleClick function will look like: $scope.singleClick = function () { if ($scope.clicked) { $scope.cancelClick = true; return; } $scope.clicked = true; $timeout(function () { if ($scope.cancelClick) { $scope.cancelClick = false; $scope.clicked = false; return; } //do something with your single click here //clean up $scope.cancelClick = false; $scope.clicked = false; }, 500); }; And the doubleClick function will look normal: $scope.doubleClick = function () { $timeout(function () { //do something with your double click here }); };
