http://www.codeproject.com/KB/webservices/CallWebServiceFromHtml.aspx
NOTE: my web service is live and i am able to consume it using asp.net but i am facing issue for using it in javascript.
Please help me. Thanks
If the web service URL has a different host (by domain name or port) than the one from which the HTML page is served then your JavaScript is violating the same origin policy and any browser will prevent the web service request from loading.
