What kind of script is this?

on this site http://ileech.biz/ there is a script that compels the user to click on the ad and then not close the pop up for atleast 10sec,before you can download anything.

I know you can be banned for it and blah blah....but i want to know the script he has used there.

 

from the source, i see in the head there is this:-

<script type="text/javascript">
timer = null;
ventana = null;
n = 10;
aviso = false;
function fnPopup(){
	ventana = window.open('popup.html', 'popup', 'scrollbars=1,resizable=1,width=780,height=700,left=150,top=150');
	$('input[name=btnDescargar]').val('10');
	$('input[name=btnDescargar]').attr('disabled','disabled');
	timer = setInterval("empieza_contar()", 1000);
}
function empieza_contar(){
	if(ventana != null){
		if(ventana.closed){
			alert('You Close The Popup Before 10 Seconds');
			clearInterval(timer); n = 10;
			$('input[name=btnDescargar]').val('Preparar Descarga');
			$('input[name=btnDescargar]').removeAttr('disabled');
			return;
		}
		if(ventana.frames.length == 3){
			return false;
		}else{
			n = n - 1;
			$('input[name=btnDescargar]').val(n);
			if(n == 0){
				clearInterval(timer);
				$('input[name=btnDescargar]').remove();
				$('input[name=B2]').before('<input type="submit" value="Descargar">');
			}
		}
	}
}
</script>

Code (markup):

Then on the pop up there is this:-

<frameset frameborder="0" rows="0,*">
    <frameset cols="0,*" frameborder="0">
        <frame scrolling="no" src="vacio1" name="vacio1"/>
        <frame scrolling="no" src="vacio2" name="vacio2"/>
    </frameset>

		
<frame scrolling='yes'  frameborder="1" bordercolor="#0000FF" resizable=1  location='0' src='content.html' name='popup'/></frameset>

Code (markup):

The second part actually contains the ad.

Could any one plz decode the entire thing?

 

i got 404 error on the popup
i think there might be something in popup.html

although i am not a JS expert but i think that might be the problem

 

I have got through the most of the part and the code seems to work.i have decoded it to large extent and want to modify it to suit my needs.I need a javascript expert's opinion.This is were i getting stuck.Please help me solve this:-

This is the part of code:-

$('input[name=btnDescargar]').val(n);
			if(n == 0){
				clearInterval(timer);
				$('input[name=btnDescargar]').remove();
				$('input[name=B2]').before('<input type="submit" value="313025">');

Code (markup):

For the last line ie. for the value 313025 i want this function to be added:-

onclick="javascript:togglecomments('abcd')"

Code (markup):

When i add it simply in front of it ie:-

$('input[name=B2]').before('<input type="submit" value="313025" onclick="javascript:togglecomments('abcd')">');

Code (markup):

The whole script stops working.

How can i do that?

Plz help me out.
