Window.scrollMaxY

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.

Summary

Returns the maximum number of pixels that the document can be scrolled vertically.

Syntax

JavaScript

Copy Code

<var>ypix</var> = window.scrollMaxY

ypix is the number of pixels.

Example

JavaScript

Copy Code

// Scroll to the bottom of the page
var maxY = window.scrollMaxY;

window.scrollTo(0,maxY);

Notes

Do not use this property to get the total document height, which is not equivalent to window.innerHeight + window.scrollMaxY, because window.innerHeight includes the width of any visible horizontal scrollbar, thus the result would exceed the total document height by the width of any visible horizontal scrollbar. Instead use document.body.scrollHeight. See also window.scrollMaxX and window.scrollTo.
