YAHOO.ext.Element.addListener problem

[kovtik]

On my page i have div tag:

<div id="panel"></div>

Could you explain me why I can't attach the event to the link with the folowing code:

var linkTemplate = new YAHOO.ext.DomHelper.Template('{0}');
linkTemplate.compile();
var elem = linkTemplate.overwrite('panel', ['link']);
var onClick = function(){alert();}
YAHOO.ext.EventManager.addListener(elem, 'click', onClick);
YAHOO.ext.Element.get('panel').dom.innerHTML += '';//dummy code, but it is needed in my real situation

However, if I write

elem.onclick = 'alert();';

it works fine.

It may very well be working... alert(); (empty alert) does nothing. Did you try it with something in it?

I just copied your exact code into a page (even with empty alert) and it worked perfect.

Is the id "panel" unique on your page?

In IE this works, in FF it throws an exception "not enough arguments". It I add 'Now I work' to alert it works as expected.

Sorry, Jack, I changed my first post in this topic while you were answering on it. I've added the following line to the end:

YAHOO.ext.Element.get('panel').dom.innerHTML += '';//dummy code, but it is needed in my real situation

You are adding a child element to "panel" via the template, subscribing to click on that child, and then you are overwriting that element using innerHTML. Since the element is gone, there's nothing to trigger the onclick.

So, how can I add inner html text correctly?

[jack.slocum]

By the way, there is a 3rd parameter "returnElement" on all the DomHelper insert/append/overwrite functions now that if you pass true will return a YAHOO.ext.Element instead of raw dom node.

Add it to what? The child or the parent?
