AJAX呼叫未按预期运行

Question

I am attempting to use an AJAX call to render a partial view when a radio button is selected. I have searched and have tried what appears to be the best approach via comments on Stack. When I click the radio button, I have no result, in debug, I get a Status Code: 500 Internal Server Error? Any assistance would be great.

Partial View Names:

_BOA.cshtml
_TA.cshtml
_MNB.cshtml

View:

                <td class="radio-inline">
                    @Html.RadioButton("bankSelect", "MNBConvert", false, new { @class = "radioMNB" }) MNB Conversion
                    @Html.RadioButton("bankSelect", "BOAConvert", false, new { @class = "radioBOA" }) BOA Conversion
                    @Html.RadioButton("bankSelect", "TAConvert", false, new { @class = "radioTA" }) TA Conversion
                </td>

Javascript:

<script src="~/Scripts/jquery-1.9.0.js"></script>
   <script type="text/javascript">
        $(function () {
            $("[name=bankSelect]").on('change', function () {
               // var $radio = $(this);
                var checked = $("input[name='bankSelect']:checked").val();

                $.ajax({
                    url: '@Url.Action("GetBankToConvert", "Home")',
                    data: checked,
                    type: 'GET',
                    success: function (data) {
                        $("#renderPartialView").html(data);
                    }
                });
            });
        });
    </script>

Controller:

[HttpGet]
        public ActionResult GetBankToConvert(string bankSelect)
        {
            if (bankSelect == "MNBConvert")
            {
                return PartialView("_MNB");
            }
            else if (bankSelect == "BOAConvert")
            {
                return PartialView("_BOA");
            }
            else
            {
                return PartialView("_TA");
            }
        }

Answer 1

You aren't sending a key/value pair as data, only a value .

Try

$.ajax({
    url: '@Url.Action("GetBankToConvert", "Home")',
    data: {bankSelect: checked },
    type: 'GET',
    success: function (data) {
        $("#renderPartialView").html(data);
    }
});

WHen in doubt, inspect the actual request in network tab of browser dev tools to see exactly what is sent and received among all the other components of a request
