Syntax
var unlocked = window.screen.unlockOrientation();
Return value
Returns true
if the orientation was successfully unlocked or false
if the orientation couldn't be unlocked.
Example
var unlockOrientation = screen.unlockOrientation || screen.mozUnlockOrientation || screen.msUnlockOrientation || (screen.orientation && screen.orientation.unlock); if (unlockOrientation()) { // orientation was unlocked } else { // orientation unlock failed }
