I. Description
When creating a template, you may sometimes need to pass the parameters or some values in the report to your own web page for some processing. At this time, how do you pass the values in the report to the web page?
II. Idea
Go to the webpage by setting the hyperlink and set the parameters, and then get the parameters through request.getParameter("parameter name in the hyperlink") in the webpage.
III. Example

Please refer to the completed template:
%FR_HOME%\WebReport\WEB-INF\reportlets\doc-EN\ReportApplication\FeaturesApplication\Hyperlink_pass_web_parameter.cpt
3. Web page to get parameter settings
Get the passed parameters
<%
String ID = request.getParameter("ID");
String TELEPHONE = request.getParameter("TELEPHONE");
%> The complete code:
<%@ page language="java" pageEncoding="GBK"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<%

</tr>
<tr>
<th>Telephone number:</th><td><input type="text" id="TELEPHONE" value="<%=TELEPHONE %>"/></td>
</tr>
</table>
</body>
</html>Name it update1.jsp and save it in the %TOMCAT_HOME%\webroot directory.
4. Effect preview
