Unable to get ajax post request to function properly

I am having trouble calling an MVC Controller from jQuery. I can't seem to make the call successfully. Is there any issue with the code below? I'm not receiving any errors either.

url="http://localhost:49917/Account/SaveAddress"

this.SaveAddress = function (url, addressData)
    {
            $.ajax({
                type: "POST",
                url: url,
                dataType: "json",
                data: JSON.stringify(addressData),
                contentType: 'application/json; charset=utf-8',
                success: function (responseDetail) {
                   },
                error:function(e)
                {

                },
            });
    return 0;
};

public async Task<ActionResult> SaveAddress(AddressListViewModel addressListVM)
    {
        bool response;
        string message;
        if (addressListVM.ID <= 0)
        {
            response = await Task.Run(() => AccountManager.Instance().AddAddress(addressListVM));
            message = response ? "New address added successfully." : "Failed to add new address.";
        }
        else
        {
            response = await Task.Run(() => AccountManager.Instance().UpdateAddress(addressListVM));
            message = response ? "Selected address updated successfully." : "Failed to update selected address.";
        }
        ModelState.Clear();
        return Json(new { responsestatus = response, message = message }, JsonRequestBehavior.AllowGet);
        //return PartialView("_AddressDetail", BuildAddressListEntity(
        //                                UserManager.FindById(User.Identity.GetUserId()), response, message, addressListVM.ID, true));
    }

Answer №1

Don't forget to add a closing curly bracket at the end of the this.saveaddress function

  this.SaveAddress = function (url, addressData)
  {
        $.ajax({
            type: "POST",
            url: url,
            dataType: "json",
            data: JSON.stringify(addressData),
            contentType: 'application/json; charset=utf-8',
            success: function (responseDetail) {
               },
            error:function(e)
            {

            },
        });

After all of that, make sure you include one more closing curly bracket like this:

   }

:)

Answer №2

Curious about what the console is showing? Take a peek by right-clicking if you're in Chrome, selecting Inspect, and then navigating to the Console tab. If your AJAX function is being called correctly, there should be some useful information displayed in this Console tab. It may just point you in the right direction better than I can with the details available.

Answer №3

To troubleshoot your code, insert breakpoints in both the success and error functions. If the debugger stops at the error function, it could be due to either the controller action not being found or the data not being valid JSON. Make sure to include the errorThrown parameter in the error function for better troubleshooting visibility. Remember that you don't have to stringify the data if it's already valid JSON, but if it's a string representing JSON, you'll need to use json.parse (apologies for any confusion).
