can we use javascript variable in BIRT tag library ?

Hi BIRT,
 
I am confusing about how to send value to BIRT tags in JSP page . I understood that BIRT load reportDesign files according to configuration file (\WEB-INF\web.xml). But,in this way, the report design file folder is fixed.I want to use dynamic path in my jsp page instead of static path.
I have modified the sample code ,I can get current folder and current report design file when I click the folder name (or report design file name) .But, to be clear, I didn't copy whole the code hear .my code as follows :
 
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" 
 pageEncoding="ISO-8859-1"%> 
<%@ taglib uri="/WEB-INF/tlds/birt.tld" prefix="birt" %> 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "<a data-ipb='nomediaparse' href='http://www.w3.org/TR/html4/loose.dtd'>http://www.w3.org/TR/html4/loose.dtd"></a> 
<html> 
 <head> 
 <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> 
 <title>PathFind Report Interface</title> 
 </head> 
 <body> 
 <birt:viewer id="birtViewer" baseURL="/brt-example" isHostPage="true" 
 pattern="frameset" 
 height="600" 
 width="1340" 
 format="html" 
 title="PathFind Report Interface" 
 reportDesign= design_file_path 
 ></birt:viewer> 
 </body>
<script type="text/javascript">
 design_file_path = "C:/xampp/tomcat/webapps/brt-example/report/2015.12.22k/customers.rptdesign"
 
</script> 
</html>

Hi,
 
First of all, you should have posted your question in the Integrating with BIRT Runtime forum, not here.
 
You cannot use a JS variable in a BIRT tag, but you certainly can use a JSP variable. Before your <html> tag, create a new JSP variable using the following code:
<pre class="_prettyXprint _lang-html">
<%!
String design_file_path = "report/2015.12.22k/customers.rptdesign";
%>
</pre>
Then in the BIRT tag, pass the value of your JSP variable to the reportDesign attribute, making sure you surround it with quotes:
<pre class="_prettyXprint _lang-html">
<birt:viewer id="birtViewer" baseURL="/brt-example" isHostPage="true"
pattern="frameset"
height="600"
width="1340"
format="html"
title="PathFind Report Interface"
reportDesign="<%=design_file_path%>"
></birt:viewer>
</pre>
Hope this helps,
