Checking if the event is triggered by the window in javascript -

is there way check if event triggerd 'window'?

i tried following window not have method called issamenode():

if(window.issamenode(ev.srcelement)){     alert(); } 

why not use this?

if(e.srcelement === window) 

that seems work in webkit console fine when resize window after running

$(window).resize(function(e){ console.log( e.srcelement === window) }); // returns true
