Window: scrollMaxY 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.

TheWindow.scrollMaxY read-only property returns themaximum number of pixels that the document can be scrolled vertically.

Value

A number.

Examples

// Scroll to the bottom of the pagelet maxY = window.scrollMaxY;window.scrollTo(0, maxY);

Notes

Do not use this property to get the total document height, which is not equivalent towindow.innerHeight + window.scrollMaxY, becausewindow.innerHeight includes the width of any visible horizontalscrollbar, thus the result would exceed the total document height by the width of anyvisible horizontal scrollbar. Instead usedocument.body.scrollHeight. See alsowindow.scrollMaxX andwindow.scrollTo.
