c# - JSON request returns object error using JQUERY -


i have aspx page returns valid json - when called via jquery can see in fiddler json returned error thrown [object error].

   protected void page_load(object sender, eventargs e)    {     string json = "{\"name\":\"joe\"}";     response.clearheaders();     response.clearcontent();     response.clear();     response.cache.setcacheability(httpcacheability.nocache);     response.contenttype = "application/json";     response.contentencoding = encoding.utf8;     response.write(json);     response.end();    }

the html page consuming page in different domain, , using jsonp. 

function jsonpcallback(response){     alert(response.data); }  $(document).ready(function(){               $.ajax({                 url: 'http://localhost:30413/getprice.aspx',                 datatype: 'jsonp',                 error: function(xhr, status, error) {                     alert(error);                 },                 success: jsonpcallback             });  });

when aspx page requested valid json returned browser, when jquery call made json returned callback function not called , expected ";" js error [object error] message displayed. below request , responses made.

i've tried every variation of request same result. using request jquery sample below because works in last sample shown below.

get http://localhost:30413/price.aspx?callback=jquery17105556924406763212_1338876162569&_=1338876162581 http/1.1 accept: application/javascript, */*;q=0.8 referer: http://alpha.tigerdirect.com/applications/b2b/varinfo.asp accept-language: en-us user-agent: mozilla/5.0 (compatible; msie 9.0; windows nt 6.1; wow64; trident/5.0) accept-encoding: gzip, deflate host: localhost:30413 connection: keep-alive pragma: no-cache cookie: asp.net_sessionid=d4pje2hgm2beznslfpp4pii5    http/1.1 200 ok server: asp.net development server/10.0.0.0 date: tue, 05 jun 2012 06:02:42 gmt x-aspnet-version: 4.0.30319 cache-control: no-cache pragma: no-cache expires: -1 content-type: application/json; charset=utf-8 content-length: 14 connection: close  {"name":"joe"}

this sample works

function jsonpcallback(response){     alert(response.data); } $(document).ready(function(){          $.ajax({             url: 'http://api.bitbucket.org/1.0/repositories/retroviz/webformsthemeswitcher/src/tip/.hgignore',             datatype: 'jsonp',             error: function(xhr, status, error) {                 alert(error);             },             success: jsonpcallback         }); });

change url in ajax url: http://localhost:30413/getprice.aspx?callback=?

and 

if(request.querystring['callback']!=null){     string callback = request.querystring['callback'];     string json = "{\"name\":\"joe\"}";     response.clearheaders();     response.clearcontent();     response.clear();     response.cache.setcacheability(httpcacheability.nocache);     response.contenttype = "application/json";     response.contentencoding = encoding.utf8;     response.write(callback + "(" + json + ")");     response.end(); }

in jsop, wrap response in callback function call. call function in javascript.
