發送多個參數當接近一個modalInstance

Question

我有模態一個角的項目，我想送多個（兩個）參數，當我關閉，問題是它給不確定的第二個參數，我的代碼如下

/*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()); 
    }); 
}

你不能這麼做，因爲承諾只能解析爲一個值，你可以將它們組合成一個對象。

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

並在解決承諾時相應地閱讀它們。

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

側面說明：

隨着打字稿或通天或任何其他ES6填充工具，你可以使用對象的解構語法和寫是：

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