使用 javascript / jquery 滚动到页面顶部？

Question

I've a <button> on the page, when this button is pressed a hidden <div> is shown using jQuery.

How do I scroll to the top of the page using a JavaScript/jQuery command in that function? It is desirable even if the scroll bar instantly jumps to the top. I'm not looking for a smooth scrolling.

If you don't need the change to animate then you don't need to use any special plugins - I'd just use the native JavaScript window.scrollTo method -- passing in 0,0 will scroll the page to the top left instantly.

window.scrollTo(x-coord, y-coord);

Parameters

• x-coord is the pixel along the horizontal axis.
• y-coord is the pixel along the vertical axis.
