Snap to top of window in jquery

How would I make the 开发者_运维百科window snap to the top of the page on an event in jquery?

This scrolls the window to the top of the page, if that's what you're after...

window.scrollTo(0,0);

I would suggest (edited based on @Aaron's comment):

$("html, body").scrollTop(0);
