The Element.scrollTop property gets or sets the number of pixels that the content of an element is scrolled upward. An element's scrollTop is a measurement of the distance of an element's top to its topmost visible content. When an element content does not generate a vertical scrollbar, then its scrollTop value defaults to 0.
Syntax
// Get the number of pixels scrolled var intElemScrollTop = someElement.scrollTop;
After running this code, intElemScrollTop is an integer corresponding to number of pixels that the element's content has been scrolled upward.
// Set the number of pixels scrolled element.scrollTop = intValue;
scrollTop can be set to any integer value, with certain caveats:
- If the element can't be scrolled (e.g. it has no overflow or if the element is non-scrollable),
scrollTopis set to0. - If set to a value less than
0,scrollTopis set to0. - If set to a value greater than the maximum that the content can be scrolled,
scrollTopis set to the maximum.
