Angularjs ng-click:如何获得`this`数据？

Question

假设我在带有角度ng-click事件的列表中有这个项目.

<a data-id='102' ng-click='delete()'>Delete</a>

如果this那么我如何获得数据/信息？

        $scope.delete = function() {

             var id = $(this).attr('data-id');
             console.log(id); // I want to get 102 as the result
             if (confirm('Are you sure to delete?')) {
                $('#contactsGrid tr[data-id="' + id + '"]').hide('slow');

            }
         };

Answer 1

正确的解决方案是将id作为参数传递给delete函数

<a data-id='102' ng-click='delete(102)'>Delete</a>

然后

    $scope.delete = function(id) {
         console.log(id); // I want to get 102 as the result
         if (confirm('Are you sure to delete?')) {
            $('#contactsGrid tr[data-id="' + id + '"]').hide('slow');

        }
     };

这不应该做,只是为了证明

在里面ng-click你可以使用$event,所以

<a data-id='102' ng-click='delete($event)'>Delete</a>

然后

$scope.delete = function (e) {
    var id = $(e.target).data('id');
    console.log(id); // I want to get 102 as the result
};
