How can I pass a PHP variable to Javascript variable from two separate pages?
<?php   $myvar=10;   ?>

<script type="text/javascript">
    jsvar = <?php echo $myvar; ?>;
    document.write(jsvar);
</script>

$.get('page2.php', function(data) {
    alert( data );
});

<?php
require_once('page2.php');
?>

<script type="text/javascript">
    jsvar = <?php echo $myvar; ?>;
    document.write(jsvar);
</script>
