Passing Parameters between the tabs in single JSP

[Shashi karnati]

HI , Here my problem is i am using tabs in jsp,
and i am using the <a href="#another_tab?id=1"></a>
this going to another tab, but in another_tab
trying to get request.getparameter("id") is not writing any return ?
Please help me out.

My code is :
<ol id="toc">
<li><a href="#query_list"><span>Query List</span></a></li>
<li><a href="#query_desc"><span>Compose Query</span></a></li>
<li><a href="#statistic_report"><span>Statistic Report </span></a></li>
</ol>

<div class="content" id="query_list">
<a href="#query_desc?id=-1&page=query_desc">To Compose New Query </a>
</div>
<div class="content" id="query_desc">
<% int id = 0;
if (request.getParameter("id") != null ) {
id = ParamUtil.parseInt(request.getParameter("id"));
}
%>
</div>

As far as I understood you have only one JSP and you are not submitting it, right? So you are not throwing a request and you don't get any value from it, it seems logical to me.

Can you put all your JSP? And please surround your code with [code] [/code] tags

Yes Albert,
you are right, these all present in one jsp,
and Here actually my mistake is passing value through anchor tag sooo.. its making new request.
here i need to use the <forward> method.
kindly help me ..
my code is :

 	 <ol id="toc">
	    <li><a href="#query_list"><span>Query List</span></a></li>
	    <li><a href="#query_desc"><span>Compose Query</span></a></li>
	    <li><a href="#statistic_report"><span>Statistic Report </span></a></li>
	</ol>
		<div class="content" id="query_list">
		    <h4>List of Queries :</h4>
		    <center>
		    <table style="background-color: #6495ED;" WIDTH="65%" border="1" cellpadding="0" cellspacing="0">
		    	<tr>
					<th align="center">Sr.No: </th>
					<th align="center">Select </th>
					<th align="center">Query_id </th>
				</tr>	
				<tr>
					<td colspan="7">   
						<a href="#query_desc?id=-1&page=query_desc">To Compose New Query </a> <!--  Problem with this anchor tag -->
					</td> 
				</tr>
<%				System.out.println("div  1 having the list and size is ");
				if (complaintParticularList.size() != 0) {
					int sr_no = 1;
					for (ComplaintParticulars particulars : complaintParticularList ) {
%>
				    	<tr>
				    		<td align="center"><%= sr_no++ %></td>
				    		<td align="center"><a href="#query_desc?id=<%= particulars.getQuery_id() %>&page=query_desc" >select </a></td>  <!--  Problem with this anchor tag -->
				    	</tr>
	    </table>
		    </center>
		</div>
		<div class="content" id="query_desc">
<%			System.out.println("div  2 getting id from parameter ");
			int id = 0;
			if (request.getParameter("id") != null ) {
				id = ParamUtil.parseInt(request.getParameter("id"));
			}
			System.out.println("div  2 getting id from parameter .....id isssss...." + id);
%>
		   	 <form name="frm" action="complaint_redressal.jsp" method="Post" onSubmit="return Validate()" >	
				<input type="hidden" value="<%= emp_id %>" name="emp_id">
				<input type="hidden" id="action" name="action" value="${action}" />

As far as I know, and maybe I am wrong, when you click a link to an anchor in your same page via #myAnchor you don't submit the page, it's just a way of telling the browser that it has to scroll to that place. Maybe I am wrong but I think this is what happends in that situation.

[Shashi karnati]

Yes your right... as mentioned earlier my mistake wass...
here it's not creating a request with id, it's just passing control to the next tab.

[Albareto McKenzie]

But you don't 'pass' anything, you have everything in your HTML at that time so you should get a way of getting the id from the link you have clicked in, you can invoke a function in the anchor and set a global js variable with the id, then pick it in the form, but I find this a bit weird, I cannot think now of a cleaner solution.
