Here is solution : - By using XMLHttpRequest connect to cross domain wcf service. - Pass the parameters using the xhr.send() method. function createCORSRequest(method url) { var xhr = new XMLHttpRequest(); if (  withCredentials in xhr) { xhr.open(method url true ); } else if ( typeof XDomainRequest !=  undefined ) { xhr = new XDomainRequest(); xhr.open(method url); } else { xhr = null ; } return xhr; } function CORSURL() { var val = document.getElementById( ' val' ).value; var url =  http://Service1.svc/UserRegistration ; var passVal = new Object(); passVal.FirstNmae=  Avinash ; passVal.LastName=  Patil ; passVal.EmailId=  Email ; var jsonText2 = JSON.stringify(passVal) ; var xhr = createCORSRequest( ' POST'  url); if (!xhr) { alert( ' CORS not supported' ); } xhr.onload = function () { var text = xhr.responseText; var result=JSON.Parse(xhr.responseText); // access object values using property name alert(text+  !!!@ ); }; xhr.onerror = function () { alert( ' there is an error.' ); }; xhr.setRequestHeader( ' Content-Type'  ' application/json' ) ; xhr.send(jsonText2); } *** Need to add an headers for your service on server : Name : Value -------------------------------------------------------- Access-Control-Allow-Credentials : true Access-Control-Allow-Headers : content-type Content-Type : application/json Access-Control-Allow-Methods : GETPOSTOPTIONS Access-Control-Allow-Origin : * Access-Control-Max-Age : 100000 --------------------------------------------------------- These headers need to set in web.config file of your wcf service. or you can use IIS to set these headers . In IIS in feature view you will see 'Http Response Headers' where you need to set these headers. --Avinash

What do you mean by cross domain? If you have a WCF service it can be available from any application if hosted publicly. So it does not matter from where you call it.
