http://book.mentaframework.org/forums/show/33.page JForum - http://www.jforum.net Its turn easy put Beans, Maps, Sets, and String to ajax response.

It structure is simple, look like this:
[code]
function getAnything(){

var request = new mtw.request();

request.setUrl("YourAction.mtw");

request.onSuccess(callbackFuncion);

request.send();
}
[/code]

on 3 line, we create an object that will build de request.
on 5 line, we tell it what URL/action we want to call.
on 7 line, we tell it what JavaScript function will receive de response from request.
on 9 line, we send de build request to server.

The callback function can be any JavaScript function, and the [i]httptransport[/i] will be send together it.
[code]
function callbackFunction(transport){

var text = transport.responseText;

var xml = transport.responseXML;

}
[/code]

But calm, MentaAjax also has a function that handle with response, and it's name is mtw.response.
[code]
function callbackFunction(transport){

var response = new mtw.response();

}
[/code]

Now lets go to build a simple example.

I want to send my name to java code, turn it to uppercase and return to my page.

JSP:
[code]
<%@ taglib uri="/WEB-INF/lib/mentawai.jar" prefix="mtw" %>

<mtw:ajaxConfig />

<input type="text" name="myName" id="myName">


<input type="button" onclick="goMenta();">



<div id="myNameHere"> </div>

<script type="text/javascript">

function callbackFunction(transport){

var response = new mtw.response();

var text = response.getString();

var e = document.getElementById("myNameHere");

e.innerHTML = text;

}

function goMenta(){

var inputValue = document.getElementById("myName").value;

var request = new mtw.request();

request.setUrl("TestAction.getName.mtw");

request.addParameter("myName", inputValue);

request.onSuccess( callbackFuncion );

request.send();

}

</script>
[/code]
