How to detect browser support for pageShow and pageHide?

How can we do JavaScript object detection for pageShow and pageHide handlers?

if( /* pagehide is supported */ ){
   window.addEventListener('pagehide', exitFunction, false);
}
else{
    window.addEventListener('unload', exitFunction, false);
}
Solution 
  • if ('onpagehide' in window) {
   window.addEventListener('pagehide', exitFunction, false);
} else {
   window.addEventListener('unload', exitFunction, false);
}
