Problem with javascript confirm() in a JSP

Question

I'm trying to use a confirm() box in a jsp. I've looked at tons of examples and I still have the same problem. If I just add this to my page the prompt will pop up as expected: (of course it doesn't really do anything.)<SCRIPT LANGUAGE="JavaScript">
confirm( "Are you sure you want to delete?" )
</SCRIPT>As soon as I add an if clause around it it doesn't even pop up anymore, such as:if (confirm("Are you sure you want to delete?")){
<%
     Do some jsp stuff
%>
else {
<%
     Do some jsp stuff
%>
}I can include more of the code if needed. This code is for deleting some files, so I want to add an "are you sure prompt?". If they hit ok it will delete, otherwise cancel the operation.
I assume that the "if confirm( "Are you sure you want to delete?" ) " should wait for a reponse before continuing. Any help is appreciated.
Thanks,
James

You can use Javascript to confirm a delete, and delete an object in the following manner.
//link to delete an object..
<a href="thisPage.jsp?delete=<%= itemID %>"
   onClick="return confirm('Are you sure you wish to delete this item?');">delete</a>Then, at the top of the JSP pageif(request.getParameter("delete") != null)
   //do whatever to delete, then load the page as normal
}Now, your item will be deleted, and the page will be refreshed to show the changes.
