删除按钮上的确认对话框

Question

我正在使用Angular处理应用程序。

我目前有一个删除按钮，附有onClick()

的确认信息

<a class="delete button" href="#" onClick="return confirm('Are you absolutely sure you want to delete?')" ng-click="remove_user(user, $event)" ></a>

问题是当确认弹出时，“确定”和“取消”都删除了该项目，我错过了什么来取消“取消”以简单取消？

Answer 1

也许只需使用角度点击处理程序并执行确认逻辑就值得一试。

function FooController($scope, $window) {
  $scope.removeUser = function() {
    var deleteUser = $window.confirm('Are you absolutely sure you want to delete?');

    if (deleteUser) {
      $window.alert('Going to delete the user');
    }
  }
}

function FooController($scope, $window) {
  $scope.removeUser = function() {
    var deleteUser = $window.confirm('Are you absolutely sure you want to delete?');

    if (deleteUser) {
      $window.alert('Going to delete the user');
    }
  }
}

对于未来的读者来说，这有点晚了，就像我15分钟前一样：

＆＃34; 角度方式＆＃34;将创建一个指令suggested here：

'use strict';

angular.module('confirm', [])
    .directive('confirm', [function () {
        return {
            priority: 100,
            restrict: 'A',
            link: {
                pre: function (scope, element, attrs) {
                    var msg = attrs.confirm || "Are you sure?";

                    element.bind('click', function (event) {
                        if (!confirm(msg)) {
                            event.stopImmediatePropagation();
                            event.preventDefault;
                        }
                    });
                }
            }
        };
    }]);

<强>用法：

<button ng-click="save()" confirm="Save Changes?">Save</button>

Answer 3

如果您使用 UI 的引导程序，我建议您使用angular-dialog-service。一旦包含模块依赖项，就可以像这样确认它。

function FooController($scope, $dialogs)
{
  $scope.removeUser = function() {
    var dlg = dialogs.confirm('Please Confirm', 'Are you absolutely sure you want to delete?');
    dlg.result.then(function () {
      console.log("User has confirmed");//do something when user confirms
    },function(){
      console.log("User has cancelled");//do something when user cancels. Can omit the 2nd function if no handling is required
    });
  }
}

它可能对其他人有帮助

HTML代码示例

<button confirmed-click="removeRowIndex(col, row)" 
        ng-confirm-box-click="Are you sure want to delete?" 
        class="btn btn-xs btn-default"/>

AngularJs代码示例

app.directive('ngConfirmBoxClick', [

      function () {
          return {
              link: function (scope, element, attr) {
                  var msg = attr.ngConfirmBoxClick;
                  var clickAction = attr.confirmedClick;
                  element.bind('click', function (event) {
                      if (window.confirm(msg)) {
                          scope.$eval(clickAction)
                      }
                  });
              }
          };
      }
]);

Answer 5

只需更换下面的onclick方法即可。

onclick="javascript:return confirm('Are you absolutely sure you want to delete?')"

Answer 6

<a class="delete button" href="#" onClick="return false" ng-click="if(confirm('Are you absolutely sure you want to delete?')){remove_user(user, $event);}" ></a>

试试这个？我认为这与您停止默认的“onclick”侦听器但不影响“ng-click”侦听器这一事实有关。相反，我将确认逻辑移动到“ng-click”监听器并且“返回false”onclick，因为您不希望链接将您带走。

Answer 7

好吧，我会创建一个函数来勾选一个全局变量并在提交

上检查它

<form onsubmit='check_delete()'
<input type='submit' onclick='set_delete()' 

的Javascript

 function set_delete(){delete_flag = 1 ;} // this is a global var set by default to 0
 function check_delete(){if(delete_flag == 1) confirm(''sure?);}
