Question

我有一个带有模态的角度项目，我想在关闭时发送多个（两个）参数，问题是它给出了未定义的第二个参数，我的代码如下

/*Modal controller*/
angular.module('assetModule')
  .controller('assetModalLocationCtrl', ['locationRESTService','$modalInstance','$scope', '$q', assetModalLocationCtrl]);

    function assetModalLocationCtrl (locationRESTService, $modalInstance, $scope, $q) {  

    this.ok = function () {   
      $scope.info.selected = selected ($scope.data.locations)
      $modalInstance.close($scope.data.locations, $scope.info.selected);      
    };
}

/*Controller that invoke the modal*/
this.modalLocation = function modalLocation (size){
    var modalInstance = $modal.open({
      animation: this.animationsEnabled,
      templateUrl: 'views/asset/assetLocationModal.html',
      controller: 'assetModalLocationCtrl',
      controllerAs: 'modalLocation',
      size: size,

    });

    modalInstance.result.then(function (selectedItem, locationList) {
     console.log(selectedItem);
     console.log(locationList);
    }, function () {
      console.log('Modal dismissed at: ' + new Date());
    });
}

您不能这样做，因为承诺只解析为一个值，您可以将它们组合到一个对象。

 $modalInstance.close({locations: $scope.data.locations, selected: $scope.info.selected});

并在承诺解决后相应地阅读。

modalInstance.result.then(function (transferData) {
   console.log(transferData.selected);
   console.log(transferData.locations);
}, function () {
    console.log('Modal dismissed at: ' + new Date());
});

旁注：

使用Typescript或Babel或任何其他ES6 polyfill，您可以使用对象解构语法，并且写为：

modalInstance.result.then({locations, selected}) => {
   console.log(locations);
   console.log(selected);
}

关闭modalInstance时发送多个参数
