Parsing JSP values on to javascript functions

Question

HI
Is it possible for Javascript functions to accept JSP variables?
For instance:
<script language="Javascript">
function selectEdit(fileID) {
   document.forms[0].recordID.value = fileID;
   document.forms[0].submit();
     </script> and a button calls the method like this:
   <input type="submit" name="Submit" value="View" onClick="selectEdit('<%= Record %>'")> I tried but was unsuccessful, can someone help?
Thanks
Eugene

Lets say you use your JSP to generate a set of links
page1.jsp:
<form target="targetPage.jsp">
<input type="hidden name="recordId");
<% for (int record=0; record<10; record++){  %>
  <input type="submit" name="Submit" value="View" onClick="selectEdit('<%= record %>')">
<%  }  %>
</form>This JSP code runs, and generates the following
<form target="targetPage.jsp">
<input type="hidden name="recordId");
<input type="submit" name="Submit" value="View" onClick="selectEdit('0')">
<input type="submit" name="Submit" value="View" onClick="selectEdit('1')">
<input type="submit" name="Submit" value="View" onClick="selectEdit('2')">
<input type="submit" name="Submit" value="View" onClick="selectEdit('3')">
<input type="submit" name="Submit" value="View" onClick="selectEdit('4')">
<input type="submit" name="Submit" value="View" onClick="selectEdit('5')">
<input type="submit" name="Submit" value="View" onClick="selectEdit('6')">
<input type="submit" name="Submit" value="View" onClick="selectEdit('7')">
<input type="submit" name="Submit" value="View" onClick="selectEdit('8')">
<input type="submit" name="Submit" value="View" onClick="selectEdit('9')">
</form>This gets sent to your browser on displayed on screen
When you click on the appropriate button, it calls your function selectEdit, which sets the value of the hidden field according to which button you pushed.
It then submits the form, to targetPage.jsp
targetPage.jsp retreives the value using request.getParameter("recordId");
which is the name of the hidden field being submitted.
JSP reacts to form submissions, and produces an HTML page.
The HTML page can then run java script
JSP gets run again when you submit the form.
Hope this helps,
