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 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.
