send javaScript variable to php variable -


possible duplicate:
how pass javascript variables php?

first thought had convert javascript php, found out cannot because of server , client side executions. want send 1 variable

<script type="text/javascript"> function scriptvariable() {             var thecontents = "the variable"; } </script>

to php variable 

<?php $phpvariable ?>

that function in javascript executes when let's click on button.

now have no idea on how assign phpvariable javascript 1 use phpvariable stuff in database. know can add url or thing , refresh page.. ajax might have use ajax method further in webpage...

so there easy way without having dump pages of code on page 1 simple thing?

as jordan said have post javascript variable server before server can handle value. can either program javascript function submits form - or can use ajax / jquery. jquery.post

maybe easiest approach this

function myjavascriptfunction() {    var javascriptvariable = "john";   window.location.href = "myphpfile.php?name=" + javascriptvariable;  }

on myphpfile.php can use $_get['name'] after javascript executed.

regards
