javascript - Confirmar cuadro de diálogo en el botón Eliminar

html5 angularjs

Question

Estoy trabajando con una aplicación usando Angular.

Actualmente tengo un botón de eliminación, que tiene una confirmación adjunta a onClick()

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

El problema es que cuando aparece la confirmación, tanto "Aceptar" como "Cancelar" eliminan el elemento, ¿qué me falta para que "Cancelar" se cancele simplemente?

Answer 1

Bueno, yo crearía una función que marque una variable global y la verifique al enviar

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

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?);}

Answer 2

Esto es un poco tarde, pero para el futuro lector, como yo hace 15 minutos:

La " vía angular " será crear una directiva como se sugiere aquí :

''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;
                        }
                    });
                }
            }
        };
    }]);

Uso:

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

                      }

              }
          };
      }
]);

Answer 4

Si está utilizando bootstrap para la interfaz de usuario , le recomiendo usar el angular-dialog-service . Una vez que incluyas las dependencias del módulo, puedes confirmarlo de esta manera.

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
    });
  }
}

Vea este ejemplo para más detalles.

Answer 5

Simplemente reemplace los métodos onclick como a continuación y funcionará.

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

Answer 6

Tal vez solo usando el controlador de clic angular y haciendo la lógica de confirmación vale la pena intentarlo.

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'');
    }
  }
}

Answer 7

<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>

¿Prueba esto? Creo que tiene que ver con el hecho de que se está deteniendo la escucha predeterminada "onclick" pero que no afecta a la escucha "ng-click". En lugar de eso, moví la lógica de confirmación al escucha "ng-click" y "retornar falso" en el clic porque no quieres que el enlace te aleje.
