PHP is executed before the content reaches the browser; it is a server-side language. If you just want to get the value of a textbox in the browser, javascript will do enable you to do that. I'll move this thread to the javascript forum so those guys can inform you how to do so.

All you have to do is change your javascript function slightly.

function fun() {
   alert(document.getElementById("uid").Value)
}
