处理ajax中的会话超时

在我的MVC应用程序中，我有以下属性来检查登录用户：

public override void OnActionExecuting(ActionExecutingContext filterContext) { .... if (filterContext.RequestContext.HttpContext.Request.IsAjaxRequest()) { filterContext.Result = new Http403Result(); filterContext.HttpContext.Response.StatusCode = 403; } ... } 

Layout.cshtml

  $("body").ajaxError( function (e, request, settings, exception) { alert('in'); if (request.status == 403) { window.location = '@Url.Action("LogOn", "Account", new {area = "", msg = "forbidden", returnUrl = HttpContext.Current.Request.RawUrl})' + window.location.hash; return; } if (request.status == 500) { window.location = '@Url.Action("AccessDenied", "Error")'; return; } if (request.status == 410) { window.location = '@Url.Action("Deleted", "Error")'; return; } window.location = '@Url.Action("Index", "Error")'; }); 

但由于某种原因，即使抛出403代码（来自ajax请求），alert（“in”）也永远不会被击中：

在DOM Ready函数中包装Ajax Error事件

 $(document).ready(function () { $(document).ajaxError(function (e, xhr, settings) { debugger; }); });
