Javascript: does scrollTop / scrollLeft change the trigger browser?

Question

I am wondering if the animation is scrollbars using Javascript triggers for the browser.

Any difference in different browser implementations?

window.pageXOffset and window.pageYOffset
document.documentElement.scrollLeft and document.documentElement.scrollTop
document.body.scrollLeft and document.body.scrollTop

Thank!
