虽然调试代码没有错误，但为什么批准索引操作没有重定向到待处理操作视图？

Question

我从事 ASP.NET MVC 项目。我面临问题，操作

ApprovalIndex

没有重定向到操作

PendingManagersRequests

，尽管没有发生错误。

我调试和跟踪断点，直到达到操作

PendingManagersRequests

并跟踪，直到我到达查看

return View(vmr);

，没有任何问题。

那么，尽管没有发生任何问题，为什么它没有重定向到视图

PendingManagersRequests

？

我的代码：当单击按钮批准提交时，它会根据

SpeakStuffComment

更新表格列

RequestNo

：

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>
}

当点击批准按钮时，它会调用控制器上的

ApprovalIndex

ResignationController

：

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

approvalIndex

控制器上调用操作

resignation

：

    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本地主机说虽然从行动

approvalindex

没有错误

当您通过 ajax 调用服务器时，重定向不起作用。

您必须在客户端“重定向”（这不是真正的重定向）：

    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);
                window.location = "/Home/PendingManagersRequests?msg=something";
            },
            failure: function (response) {
                alert(response.responseText);
            },
            error: function (response) {
                alert(response.responseText);
            }
        });
    }
