var data=eval("("+jsonString+")");// we suppose the server returns JSON data
... do something with data
};
var myRequestURL="http://myserver:8080/myapp/someurl?dothis"
var requestContent ="server, here is the information you need";
IlvAjax.post(myRequestURL, requestContent, null, fRef, null);
Or
var client=this; //use closure
var fRef = function(jsonObject) {
client.doSomething(jsonObject);
};
var jsrequest = new IlvAjax.JSRequest(this, fRef);
jsrequest.send(myRequestURL);
