防止点击从触发确认对话框(在Angular 1.2 RC3中停止工作)

Question

我正在使用此脚本在实际触发ng-click功能之前有一个确认对话框

Directives.directive('ngConfirmClick', [
  function(){
    return {
      priority: 100,
      restrict: 'A',
      link: function(scope, element, attrs){
        element.bind('click', function(e){
          var message = attrs.ngConfirmClick;
          if(message && !confirm(message)){
            e.stopImmediatePropagation();
            e.preventDefault();
          }
        });
      }
    }
  }
]);

如 http://zachsnow.com/#!/blog/2013/confirming-ng-click/所示

通过以下方式使用:

<button ng-confirm-click="Are you sure?" ng-click="remove()">Remove</button>

There are other similar scripts here on SO, but since i updated to Angular 1.2 RC3 they stopped working. The ng-click function is always fired BEFORE the actual link function is stepped into.

I also tried to increase priority and to listen to other events(touchstart, because the newest angular has this new ngtouch directives). But nothing works.

啊,我自己解决了!

最近,有角度的团队提交了改变前/后链接优先级的提交:https: //github.com/angular/angular.js/commit/31f190d4d53921d32253ba80d9ebe57d6c1de82b

现在包含在Angular 1.2 RC3中!

因此,后链接功能现在具有相反的优先级.

所以有两种方法可以解决这个问题.无论是现在使用一个负的优先级

Directives.directive('ngConfirmClick', [
  function(){
    return {
      priority: -100,  //<---------
      restrict: 'A',
      link: function(scope, element, attrs){
        element.bind('click', function(e){
          var message = attrs.ngConfirmClick;
          if(message && !confirm(message)){
            e.stopImmediatePropagation();
            e.preventDefault();
          }
        });
      }
    }
  }
]);

或者将函数转换为预链接函数

Directives.directive('ngConfirmClick', [
  function(){
    return {
      priority: 100,
      restrict: 'A',
      link: {
          pre: function(scope, element, attrs){ //<---------
                element.bind('click touchstart', function(e){
                  var message = attrs.ngConfirmClick;
                  if(message && !window.confirm(message)){
                    e.stopImmediatePropagation();
                    e.preventDefault();
                  }
                });
              }
        }
    }
  }
]);
