function getEvent(){

  if(document.all){

    return window.event;

  }

  func = getEvent.caller;

  while(func != null){

    var arg0 = func.arguments[0];

    if(arg0){

      if((arg0.constructor == Event || arg0.constructor == MouseEvent) || typeof (arg0) == "object" && arg0.prevebtDefault() && arg0.stopPropagation()){

        return arg0;

      }

    }

    func = func.caller;
