script

[etsted]

i got a little script i want to show:

 

var scrollY = 0;

var distance = 40;

var speed = 24;

function autoScrollTo(el) {

var currentY = window.pageYOffset;

var targetY = document.getElementById(el).offsetTop;

var bodyHeight = document.body.offsetHeight;

var yPos = currentY + window.innerHeight;

var animator = setTimeout('autoScrollTo(''+el+'')',24);

if(yPos > bodyHeight){

clearTimeout(animator);

} else {

if(currentY < targetY-distance){

scrollY = currentY+distance;

window.scroll(0, scrollY);

} else {

clearTimeout(animator);

}

}

}

this is supposed to clear the "animator" if yPos is greater than bodyHeight, but woudnt yPos and bodyHeight have the same value?

if not explain.

Checking that it's greater makes sure that if it somehow skips the exact bodyHeight value and has something larger the program will still stop the animation.
