Window: scrollMaxX property
Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.
The Window.scrollMaxX read-only property returns the
maximum number of pixels that the document can be scrolled horizontally.
Value
A number.
Examples
// 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.
