为什么批准索引操作没有重定向到挂起的操作视图，尽管调试代码没有错误？

问：

我从事一个 ASP.NET MVC 项目。我遇到问题操作没有重定向到操作，尽管没有发生错误。ApprovalIndexPendingManagersRequests

我调试并跟踪断点，直到到达操作，并跟踪直到我到达查看，没有任何问题。PendingManagersRequestsreturn View(vmr);

那么，为什么它没有重定向到视图，尽管没有发生任何问题呢？PendingManagersRequests

我的代码：当点击按钮批准提交时，它会根据以下条件更新表列：SpeakStuffCommentRequestNo

using (Html.BeginForm("ApprovalIndex", "Resignation", new { id = Model.RequestNo }, FormMethod.Post, htmlAttributes: new { @style = "display:inline;" }))
{
    @Html.AntiForgeryToken()
        
    <a onclick="submit();" class="btn btn-primary" style="min-width: 100px;
            margin-left: 5px;">
        <i class="glyphicon glyphicon-ok"></i> Approve 
    </a>
}

当单击批准按钮时，它会调用控制器：ApprovalIndexResignationController

public class ResignationController : Controller
{
    [HttpPost]
    public async Task<ActionResult> ApprovalIndex(ResignationRequester REQ)
    {
        string errorMsg = string.Empty;
        string requestStatus;

        Workforce.ResignationUpdateLineManangerApproval(id, true,Convert.ToInt32(Session[SessionKeys.UserCode]));

        return RedirectToAction("PendingManagersRequests", new { msg = $"Request NO {REQ.RequestNo} has been accepted " +
                        $"successfully." });
    }
}

jQuery在控制器上调用操作：approvalIndexresignation

    function submit() {
        var ResignationRequester = new Object();
        ResignationRequester.RequestNo = document.getElementById("RequestNo").innerHTML.trim();
        ResignationRequester.EmpID = document.getElementById("EmpID").innerHTML.trim();
        ResignationRequester.SpeakStuffComment = document.getElementById("SpeakStuffComment").value;

        if (ResignationRequester != null) {
            $.ajax({
                type: "POST",
                url: '@Url.Action("ApprovalIndex", "Resignation")',
                data: JSON.stringify(ResignationRequester),
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (response) {
                    console.log(response);
                },
                failure: function (response) {
                    alert(response.responseText);
                },
                error: function (response) {
                    alert(response.responseText);
                }
            });
        }
    }
</script>

public async Task<ActionResult> PendingManagersRequests(string msg, string errorMsg)
{
    ViewModelRequests vmr = new ViewModelRequests();
      
    vmr.MyRequests = Workforce.GetPendingToDisplayMyRequests(Session[SessionKeys.UserCode].ToString());

    ViewBag.msg = msg;
    ViewBag.errorMsg = errorMsg;

    return View(vmr);
}

最后，我只得到这个弹出的本地主机说，虽然从操作中没有错误approvalindex
