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.scrollMaxX
read-only property returns the maximum number of pixels that the document can be scrolled horizontally.
Syntax
xMax = window.scrollMaxX
xMax
is the number of pixels.
Example
// Scroll to right edge of the page let maxX = window.scrollMaxX; window.scrollTo(maxX, 0);
Notes
Do not use this property to get the total document width, which is not equivalent to window.innerWidth + window.scrollMaxX, because window.innerWidth
includes the width of any visible vertical scrollbar, thus the result would exceed the total document width by the width of any visible vertical scrollbar. Instead use document.body.scrollWidth
. See also window.scrollMaxY
.
