});
</script>
</head>
<body>
<IMG id="image" SRC="images/2.png" width="400px">

</html>
EDIT
In Page1 onclick event we are simply calling the filename() function. This function in turn is appending the imageId in the url of the second page. Now, when you land on the second page, the $(document).ready(function(){}) is taking the imageId from the url and setting the SRC of the <IMG> tag with the image 1.png.
Try below code:
function showImage(imagePath){
window.location.href= "www.yourdomain.com/yourDirectory/path/showImage?image_path="+imagePath;
}
and on the above url you can use this path to show image + any other content, whatever is required.
Here is my Code:
<%#page contentType="text/html"%>
<%#page pageEncoding="UTF-8"%>
<%#page import="java.sql.*"%>

</form>
</body>

Here in the above function onclick of a button i want to execute the scriptlets which is inside javascript?
you can also use this:
<%#page contentType="text/html"%>
<%#page pageEncoding="UTF-8"%>
<%#page import="java.sql.*"%>
<%
String ServerName = (String)request.getParameter("ServerName");
%>

ServerName: <input type="text" name="ServerName" required> <br><br>
<input type="submit" id="btnSubmit" name="btnSubmit" />
</div>
</form>
</body>
</html>
You can, but if you want the result to be passed to the JavaScript you have to output something.
var x='<%= request.getParameter("ServerName"); %>';
^ output!
… and unless you take measures to escape that data, you render yourself vulnerable to XSS attacks.
(And, obviously, this won't work until the form is actually submitted)
Can anyone explain me why this piece of code does not work in Eclipse. I tried to compile the code on this site http://jsfiddle.net and it's working.

I try to add JQuery DataTable to my JSP page but nothing happens. I ckecked that all files: jquery.dataTables.js, jquery.dataTables.css, jquery.js is found.
Here's my JSP page:

I am trying to call a javaScript function that's in .../js/index.js file to .../index.jsp file.
Any suggestion would be helpful.
Here is code within both file:
index.js
function testing() {
if ("c" + "a" + "t" === "cat") {
document.writeln("Same");
} else {
document.writeln("Not same");
};
};
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>Insert title here</title>
</head>
<body>
<script type="text/javascript" src="js/index.js">
<!-- I want to call testing(); function here -->
</script>
</body>
</html>
First reference the external index.js file and then call the function in an inline script element:
<%# 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>Insert title here</title>
</head>
<body>
<script type="text/javascript" src="js/index.js"></script>
<script type="text/javascript">
testing();
</script>
</body>
</html>
By the way you have an error in your test.js function. You shouldn't put a ; after if/else conditions, neither at the end of your function declaration. The correct syntax is:
function testing() {
if ("c" + "a" + "t" === "cat") {
document.writeln("Same");
} else {
document.writeln("Not same");
}
}
or:
var testing = function() {
if ("c" + "a" + "t" === "cat") {
document.writeln("Same");
} else {
document.writeln("Not same");
}
};
you can do like this
<%# 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">
<script type="text/javascript" src="js/index.js"></script>
<title>Insert title here</title>
</head>
<body>
<input type = "button" onclick = "javascript:testing()"/>
</body>
</html>
It is easiest
