I really don't see why people keep pointing out that php is server
side and javascript is client-side, is if that makes it impossible to
implement. JSP is server-side as well, and you can embed JSP scriplets
and what not into javascript just fine. Just because code is server
side doesn't mean it has to execute on the first pass (which seems to
be what php does) .... i.e if I wanted to do something like this in
JSP it would work just like you would expect.

<script>
function foo() {
<%
String bar = "foobar";

if(bar != null) { %>
//do some javascript stuff
<% } %>
alert(<%=bar%>);
etc.....
}
</script>

<input type="button" value="penguins" onclick="foo();"/>

Not that I'm saying you should switch to Java webapps especially since
webhosts charge too much to run JBoss, Tomcat, etc and Java Struts or
JSF is much harder to learn and implement. But .....
