在同一页面内将变量从JS传递给PHP [关闭]

I know this has been answered many times but what i am looking for is the passing of variables within the same page. I understand that PHP is a server side script while JS is the client side thus when the page loads, it will load PHP before JS thus it is impossible to do so.

What i am seeking is an alternative method to perform my JS task which is to take the value after the ? in the address bar (//localhost/Task/delete.php?ID=1). Else alternatively is there a way around passing the variable into PHP as the value will be used to execute a SQL query.

Thanks

<script language="javascript" type="text/javascript" >
var url = window.location.href;
var params = url.split('?ID=');
var fdf = (params[1])
alert(fdf);

</script>

<?php
$random = $_GET["fdf"];

echo $random;
?>
