The Window.scrollBy() method scrolls the document in the
window by the given amount.
Syntax
js
scrollBy(xCoord, yCoord)
scrollBy(options)
Parameters
xCoord-
The horizontal pixel value that you want to scroll by.
yCoord-
The vertical pixel value that you want to scroll by.
options-
An object containing the following properties:
top-
Specifies the number of pixels along the Y axis to scroll the window or element.
left-
Specifies the number of pixels along the X axis to scroll the window or element.
behavior-
Specifies whether the scrolling should animate smoothly (
smooth), happen instantly in a single jump (instant), or let the browser choose (auto, default).
Return value
None (undefined).
Examples
To scroll down one page:
js
window.scrollBy(0, window.innerHeight);
To scroll up:
js
window.scrollBy(0, -window.innerHeight);
Using options:
js
window.scrollBy({
top: 100,
left: 100,
behavior: "smooth",
});
Notes
window.scrollBy() scrolls by a particular amount, whereas
window.scroll() scrolls to an absolute position in the document. See also
window.scrollByLines() and window.scrollByPages().
