Summary

Returns the number of pixels that the document has already been scrolled horizontally.

Syntax

var x = window.scrollX;

Parameters

  • x is the number of pixels that the document is currently scrolled from the left.

Example

// If scrollX is greater than 400, reset scroll position to the top left of the document.
if (window.scrollX > 400) {
  window.scroll(0,0);
}

Notes

The pageXOffset property is an alias for the scrollX property:

window.pageXOffset == window.scrollX; // always true

For cross-browser compatibility, use window.pageXOffset instead of window.scrollX. Additionally, older versions of Internet Explorer (< 9) do not support either property and must be worked around by checking other non-standard properties. A fully compatible example:

var x = (window.pageXOffset !== undefined)
  ? window.pageXOffset
  : (document.documentElement || document.body.parentNode || document.body).scrollLeft;

var y = (window.pageYOffset !== undefined)
  ? window.pageYOffset
  : (document.documentElement || document.body.parentNode || document.body).scrollTop;
