RE: JavaScript Trouble, dynamic script not running JS for news feeds?


Ok I was thinking of putting this up on my page and trying it but I have a
suggestion for debugging this.  Limit to testing it with one rss feed and
simplify the code as much as you can before you test it.  Once you get the
more simple version working then you add the extra feeds.

Subject: JavaScript Trouble, dynamic script not running JS for news feeds?

Hi, I've been trying to get this thing working for a few days now, but I
think I'm missing something.

I'm trying to work out a better and more dynamic method for loading the news
feeds at http://gutterstar.net/news.php All of these news feeds are being
loaded using the script at http://gutterstar.net/rss , which is rendered
within a standard <script type="text/javascript" 
src="http://rssScriptGenURLOutput.php?stuffVariables";></script>

My idea is that, if I could dynamically load each RSS feed when a link is
clicked, the load delay would be much less, and no page refresh would occur
to disrupt navigation.

So I wrote the test page at http://gutterstar.net/news_test.htm Which, by
all that I've read, should work, except that it doesn't...

I was able to get the code below to work briefly when the page first loaded,
but nothing after that. Now it doesn't even work when the page loads for
some reason. The dynamic aspect just isn't working at all. I've saved out
the live DOM to see if it's adding the correct script to the right Div, and
everything appears to be updating correctly in the DOM, but I can't see
anything on the page itself, which is really weird. Anyone know what I'm
doing wrong?
