I was trying to do a very simple image-swap effect:
<div id="foo">
<p><img ... /></p>
</div>
<div id="bar">
<p><img ... /></p>
</div>
$('foo').observe('click',function(evt){
$('bar').update(this.down('p'));
});
I expected both #foo and #bar to contain the same image, but instead,
#foo was empty, and #bar contained the image originally in #foo.
I resolve the problem by changing my method from copying the P to
simply making the two images have the same src attribute.
But can anyone explain what my conceptual failure was here? Why did
update() seem to do what I would have expected the following
construction to do:
$('bar').update(this.down('p').remove());
???
Thanks in advance,
Walter
