FILE NAME - aja1.jsp
I am using AJAX for sending parameter on the same page using GET Method.

How can I process those parameter in my JSP code and get back the resuld in responseText Object.
Forexample - In PHP we can echo pramater to access by responseText Object.

My code is given below...



<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script type="text/javascript">
function sendparm(){


var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
var ajaxDisplay = document.getElementById('aj_id');
ajaxDisplay.innerHTML = ajaxRequest.responseText;

}
}
var nm= document.form1.txt1.value;
var url = "aja1.jsp"
var queryString= "?name=" + nm;
xmlhttp.open("GET",url+queryString,true);

xmlhttp.send(null);
}
</script>
<title>JSP Page</title>
</head>
<body>



<form name="form1" method="get" action="aja2.jsp" value="form1">
<input type="text" value="" name="txt1"></input>
<input type="button" value=click" name="btn1" onclick="sendparm()"></input>

<%
String str = request.getParameter("name");
//////WHAT SHOULD I DO NOW TO PROCESS THIS STR VARIABLE AND TO ACCESS IN AJAX TO INSERT IN HTML
%>

</form>

<div id='aj_id'>Your result will display here</div>

<input type="text" value="" id="asdaasd" name="txt2"></input>

<h1>Hello World!</h1>
</body>
</html>

I suggest you read a basic tutorial about AJAX.

And please make sure to use code tags when posting code in the forums. Unformatted code make it harder to read the content.
 
It is sorta covered in the JavaRanch Style Guide.
