clear shopping cart content on body unload

[vineet]

hi all

i m creating a shopping cart in php.

i want to add a javascript function on body unload that when the user closes his browser then he will get an confirm alert that the shopping cart contents should get clear or remove,
if he clicks ok then the contents should get removed and if clicks cancel then nothing happens.

how is it possible with javascript. my shopping cart contents are inside the <form> tag.

<script type="text/javascript">
window.onbeforeunload = function() {
   return 'Are you sure you want to leave the page?';
};
</script>

hi nile

thanks for reply. this script gives a confirm alert but it gives alert on every refresh command also. that should not be there.

but on clicking the ok button i want to clear the contents. This script doesnt do that.

do i need to clear contents with php

Are you making it with PHP? Probably, right? So PHP, your gonna need to use ajax.
