如何在$.ajax回调中重定向到操作?

您需要使用ajax请求的结果,并使用该结果运行javascript来手动更新窗口位置你自己。例如,类似于:

// Your ajax callback:
function(result) {
    if (result.redirectUrl != null) {
        window.location = result.redirectUrl;
    }
}

UrlHelper.GenerateUrl ,这是一个MVC帮助程序,它根据操作/控制器等创建URL。)

C#:

return RedirectToAction("Action", "Controller", new { myRouteValue = foo});

JS公司:

 $.ajax({
    type: "POST",
    url: "./PostController/PostAction",
    data: data,
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    complete: function (result) {
        if (result.responseText) {
            $('body').html(result.responseText);
        }
    }
});

C#运转良好

 $.ajax({
        type: "POST",
        url: posturl,
        contentType: false,
        processData: false,
        async: false,
        data: requestjson,
        success: function(result) {
            if (result) {
                $('body').html(result);
            }
        },

        error: function (xhr, status, p3, p4){
            var err = "Error " + " " + status + " " + p3 + " " + p4;
            if (xhr.responseText && xhr.responseText[0] == "{")
                err = JSON.parse(xhr.responseText).Message;
            console.log(err);
        }
    });   

Html.RenderAction 视图中的辅助对象:

public ActionResult IsReady(int id)
{
    if(true)
    {
        ViewBag.Action = "AnotherAction";
        return PartialView("_AjaxRedirect");
    }
    return Json("pending");
}

@{
    string action = ViewBag.ActionName;
    Html.RenderAction(action);
}
