Posted 2021-05-20

function listen(event, elem, func) {
    elem = $(elem);
    if (elem.addEventListener)  // W3C DOM
        elem.addEventListener(event,func,false);
    else if (elem.attachEvent) { // IE DOM
         var r = elem.attachEvent("on"+event, func);
	return r;
    }
    else throw 'No es posible añadir evento';
}
