window.resizeBy Redirect 1

« window

Summary

Resizes the current window by a certain amount.

Syntax

window.resizeBy(xDelta, yDelta) 

Parameters

  • xDelta is the number of pixels to grow the window horizontally.
  • yDelta is the number of pixels to grow the window vertically.

Example

// shrink the window 
window.resizeBy(-200, -200);

Notes

This method resizes the window relative to its current size. To resize the window in absolute terms, use window.resizeTo.

Since Firefox 7, it's no longer possible for a web site to change the default size of a window in a browser, according to the following rules:

  1. You can't resize a window or tab that wasn’t created by window.open.
  2. You can't resize a window or tab when it’s in a window with more than one tab.

Specification

DOM Level 0. Not part of specification.
