[Coefficient-devel] Asynchronous JavaScript -AJAX

[Miguel P. <mr_...@ho...>]

I'm trying to write a javascript using AJAX to return some values from the
server.

 

For example

 var req;

 

function validate() {

   var idField = document.getElementById("userid");

   var url = "validate?id=" + escape(idField.value);

   if (window.XMLHttpRequest) {

       req = new XMLHttpRequest();

   } else if (window.ActiveXObject) {

       req = new ActiveXObject("Microsoft.XMLHTTP");

   }

   req.open("GET", url, true);

   req.onreadystatechange = callback;

   req.send(null);

}

 

My question is how do I get the values back from coefficient.  I can execute
the methods and a module but I don't have access to response.getWriter from
ctx.

 

Do I need to write a next class, modify CoefficientServlet, or is there a
way to do this via ctx (coefficientcontext)?

 

Any help would be deeply appreciated.
