The Example for show and hide a div in java jquery (java server page) web applicaion. Event triggering in java web application using jquery
The program will show and hide the content div, on user selecting a particular menu. Here i used only one jsp page where all the div presents. This web application demonstrate a simple jquery.hide() and jquery.show() method. JQuery is powerful API that provides triggering of event
index page : index.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Jquery trigger event in java web application</title>
</head>
<body>
<jsp:forward page="/jsp/home.jsp"></jsp:forward>
</body>
</html>
The index page just redirect to request to home page (ie,home.jsp)
here i used JSP tags to forward the request
The above example shows the working of JSP tags
home page : home.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
