set this code at <head> , script at head is executed before the body page is loaded , you can insert it also at the body befor the html section you don't want it to be loaded.
<script type='text/javascript'>
var x = prompt("enter name");
if(x===""){
window.stop();
}
</script>

var s = prompt("Enter Value:");
if s !== ""){
document.write(" <h1> . </h1>");
}

If the user just presses ok, an empty string is returned I guess. So you could check for that

var s = prompt("Enter value:");
if ( s!== "") {
// Get input s
}

Try this..
function func() {
var s = prompt ("Please enter your bank code: \n (Just for fun,^_^) ");
if(s!=undefined) confirm (" Thanks for purchasing! \n------------------------------------- \n Apple Retail Store Seattle \n Confirm purchase: \n Macbook Air 13.3 inch 128GB \n $ 15000 ");
}

I mean not the current prompt, but the whole html, JavaScript and CSS code
