Hi Friend,
You can use Ajax. Try the following code:
1)ajaxExample.jsp:
<html>
<head>
<script>
var xmlhttp
function loadContent(str){
xmlhttp=GetXmlHttpObject();
if (xmlhttp==null) {
alert ("Your browser does not support Ajax HTTP");
return;
}
var url="getvalue.jsp";
url=url+"?q=roseindia";
xmlhttp.onreadystatechange=getOutput;
xmlhttp.open("GET",url,true);
xmlhttp.send(null);
}
function getOutput(){
if (xmlhttp.readyState==4) {
document.getElementById("var").innerHTML=xmlhttp.responseText;
}
}
function GetXmlHttpObject(){
if (window.XMLHttpRequest) {
return new XMLHttpRequest();
}
if (window.ActiveXObject) {
return new ActiveXObject("Microsoft.XMLHTTP");
}
return null;
}
</script>
</head>
<body>
<a href="javascript:loadContent('parameterValue')">Load</a>
<div id="var"></div>
</body>
</html>
2)getvalue.jsp:
<%
String q =request.getParameter("q");
out.print(q);
%>
Thanks
