jquery 写事件

Question

function AddEventListener(element, eventType, handler, capture)
{
if (element.addEventListener)
element.addEventListener(eventType, handler, capture);
else if (element.attachEvent)
element.attachEvent("on" + eventType, handler);
}if ($('#copyContrctAddress')[0]!= null )
AddEventListener($('#copyContrctAddress')[0],'click',function(event){hidePostAddress();},false);

Answer 1

$('#copyContrctAddress')[0]貌似这样写不行，我自己做的好像这样写老报错，用get(index)吧

Answer 2

$('#copyContrctAddress')[0]这样写可以，但要看他的返回值
