在ajax Asp.net Mvc中发布后如何访问会话变量。到目前为止,我已经尝试将会话值存储在隐藏字段中并声明sessionvalue。
var sesVal ='@Session [“ show_flag”]';
public ActionResult EditCustomer(int id = 0)
{
InfoModel infoObj= new InfoModel();
if (Session["show_flag"] != null){
ViewBag.show_flag= Convert.ToBoolean(Session["show_flag"]);
Session["show_flag"] = null;
return View(infoObj);
}
}
[HttpPost]
public ActionResult EditCustomer(InfoModel infoObj, int id)
{
string url = "";
Session["show_flag"] = infoObj.Show_flag(infoObj);//returns true or false
infoObj.EditCustomer(infoObj,id);
url = Url.Action("ViewCustomer");
return Json(new { newurl = url });
}
在我看来
function EditCustomer() {
var $form = $('#EditCustomerForm');
$.ajax({
type: "POST",
url: '@Url.Action("EditCustomer", "Customer", new { id = ViewContext.RouteData.Values["id"] })',
json: true,
data: $form.serialize()
}).done(function (data) {
RedirectUrl = data.newurl;
//Session["show_flag"] how can i get session value to check the condition here
});
最佳答案
您可以将其作为json响应的一部分发送。将新属性添加到要传递给Json
方法的匿名对象。
[HttpPost]
public ActionResult EditCustomer(InfoModel infoObj, int id)
{
var showFlag = infoObj.Show_flag(infoObj);
Session["show_flag"] = showFlag;
infoObj.EditCustomer(infoObj,id);
var url = Url.Action("ViewCustomer");
return Json(new { newurl = url, shouldShowFlag = showFlag });
}
在ajax方法的
done
事件中,您可以读取返回的响应的shouldShowFlag属性值。var $form = $('#EditCustomerForm');
$.ajax({
type: "POST",
url: '@Url.Action("EditCustomer", "Customer",
new { id = ViewContext.RouteData.Values["id"] })',
json: true,
data: $form.serialize()
}).done(function (data) {
var newUrl = data.newurl;
var shouldShow = data.shouldShowFlag;
alert(shouldShow);
// window.location.href=newUrl; reload to the new url ?
});
