Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
The Window.scrollMaxY
read-only property returns the maximum number of pixels that the document can be scrolled vertically.
Syntax
yMax = window.scrollMaxY
yMax
is the number of pixels.
Example
// Scroll to the bottom of the page let maxY = window.scrollMaxY; window.scrollTo(0, maxY);
Notes
Do not use this property to get the total document height, which is not equivalent to window.innerHeight
+ window.scrollMaxY, because window.innerHeight
includes the width of any visible horizontal scrollbar, thus the result would exceed the total document height by the width of any visible horizontal scrollbar. Instead use document.body.scrollHeight
. See also window.scrollMaxX
and window.scrollTo
.
