Question

I am reading someone Else’s javascript code which is listed below

window.onload = function(){
  // Listen to the double click event.
  if ( window.addEventListener ) {
    document.body.addEventListener( 'dblclick', onDoubleClick, false );
  }
  else if ( window.attachEvent ) {
  /* attachEvent is Microsoft and addEventListener is W3C */
    document.body.attachEvent( 'ondblclick', onDoubleClick );
  }
}; 

Answer 1

The name of the event is “dblclick” and the event (handling) property is called “ondblclick”. even in IE the event itself is named “dblclick” (ref.)
