web api instance property
Window: scrollMaxX property
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 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
scrollMaxY.
