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.

Rahul M... Teacher 4822 Points 23 Posts	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 + " )"; } Posted On: 27-Jun-2015 21:22
