Hi, I am trying to get data from different domain using jsonp of jquery.I am using asp.net MVC on server side. Ajax call as: function JoinUser(roomid) {
$.ajax({
type:"post",
url: $.getUrl("controllername/JoinUser"),
data: {'roomid': roomid},
contentType: "application/json;charset=utf-8",
dataType:"jsonp",
success:function (data) { },
error:function (data, status) { }
});
}
Controller Code: [AcceptVerbs(HttpVerbs.Get)]
public JsonResult JoinUser(string roomid)
{
return Json("", JsonRequestBehavior.AllowGet);
}
But am getting error. Am I missing anything.

Hi Jak, Check the following steps: I. In web.config file Add following section In <System.web>: <system.web>
<webServices>
<protocols>
<add name="HttpGet"/>
<add name="HttpPost"/>
</protocols>
</webServices>
</system.web>
In <Sytem.WebServer>: <system.webServer>
<httpProtocol>
<customHeaders>
<!--Enable Cross Domain AJAX calls -->
<remove name="Access-Control-Allow-Origin" />
<add name="Access-Control-Allow-Origin" value="*" />
</customHeaders>
</httpProtocol>
</system.webServer>
II. In Action method You need to modify action as: [AcceptVerbs(HttpVerbs.Get)]
public string JoinUser(string callback, string roomid)
{
var JSONString = new JavaScriptSerializer().Serialize("");
return callback+"( "+JSONString + " )";
}
