JavaScript - onClick to get the ID of the clicked button

Question

How do find the id of the button which is being clicked?

Answer 1

(I think the id attribute needs to start with a letter. Could be wrong.)

You could go for event delegation...

    
    
    


function reply_click(e) {
    e = e || window.event;
    e = e.target || e.srcElement;
    if (e.nodeName === 'BUTTON') {
        alert(e.id);
    }
}

...but that requires you to be relatively comfortable with the wacky event model.
