Window.scrollMaxY
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
yMaxis 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.
