Getting jsp value in javascript file

Question

I have the following code in abc.jsp:

<%@page import="soundcap.Soundcap"%>

<%

    Soundcap cfl = new Soundcap();
    var sfl = cfl.playFile();

%>

I need the value of sfl in an external javascript file (jcode.js). How can I get this value (sfl) from jsp in javascript?

Thanks, but I would like to get it into a variable like this var xy = ... what is ...? — bdfios

Thanks everyone for your suggestions. Your suggestions make sense to me but this stuff isn't just working. I am going through the entire code right now to see why it isn't working. I think its probably from my end. Thanks! — bdfios

use this...

<%
//get your sfl
 %>
  <input type="hidden" id="sfl" value="<%=sfl%>">

in your js file use

var sfl=document.getElementById("sfl").value;

Just place your JSP value in input tag like this:

<input type="hidden" id="value" value="${value}">

And get this value in JS like this:

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

Very simple:

<% 
//get your sfl
%>

<script>
var xyz = <% out.print(sfl); %>;
</script>

It didn't work. Please note that I am using an external javascript.

Then put the code from my answer in your external javascript file (after removing the script tags). @bdfios
