Passing a parameter of type List to Javascript function
javascript, list
Solution
I assume that in your javascript the `List<>` is an `Array`.
If that is the case, you can do all sorts of things with it: http://www.w3schools.com/js/js_arrays.asp
Example (calling this function will display an alert for each element in the array):
var alertAllElements = function (theArray) {
for(var x=0; x<theArray.length; x++)
alert(theArray[x]);
};
Problem
I have a function in my view, that requires calling a list, in order to execute the ajax call within it. The API that I'm using has a parameter `List<>` among its arguments. That's why I need it. Is it possible to pass a parameter of type `List<>` to a Javascript function? If yes, what's the appropriate syntax to use? I googled and didn't find an answer yet. EDIT : Here's my code Javascript function: ``` function DeleteRoom(RoomId, FloorId, userDevicesID) { $.ajax({ beforeSend: function (xhr) { xhr.setRequestHeader('verifySession', verifySession()); xhr.setRequestHeader('Authorization', '@HttpContext.Current.Session["BaseAuth"]'); }, url: "/api/Room/RemoveRoom?RoomId=" + RoomId + "&userDevicesId="+ userDevicesID, type: "DELETE", dataType: 'json', success: function (data) { // removing items from the view } }); } ``` Calling the popup that uses this function: ``` arr.push(existingdevices[i].attrs.id); //array of IDs, can be empty PopUpDeleteRoom(id, FloorId, arr); ``` The API: ``` [HttpDelete] public void RemoveRoom(int roomId, [FromUri]List<int> userDevicesId) { int currentUserId = SessionData.CurrentUser.UserID; List<Equipment> equipmentsAssociated = equipmentRepository.FindMany(e => e.RoomID == roomId).ToList(); foreach (Equipment equipment in equipmentsAssociated) { equipment.RoomID = null; equipmentRepository.Update(equipment); equipmentDeviceRepository.DeleteAllEquipmentDeviceOfZwave(equipment.EquipmentID); } foreach (int userDeviceId in userDevicesId) { userDeviceRepository.Delete(userDeviceId); //this generates a NullReferenceException that I will fix later } equipmentRepository.Save(); userDeviceRepository.Save(); roomRepository.Delete(roomId); roomRepository.Save(); } ``` Please is there a solution or a workaround for this issue?
