This is the weirdest problem I've seen so far. But upfront this is my first javascript development. I've mostly programmed in Actionscript and PHP.
I have quite a bit of javascript running on my PHP page. I had just gotten everything to work well (looking at you IE7!) and I moved one function to another place because out of the blue I was getting "function is not defined."
From there everything went wrong. Soon the page wouldn't register any functions. I moved it all to an external .js file and that solved nothing.
So I went back to where it all went wrong. One by one as I used the page I would get an undefined function error. So I moved these one by one to a different part of the page. Soon I was able to get all the code working but I had my leftover <script> tags.
<link href="css/main.css" rel="stylesheet" type="text/css">
<script type="text/javascript" src="js/jsTrace-uc.js"/>
<script type="text/javascript" src="js/dom-drag.js"/>
[B]<script type="text/javascript">
</script>[/B]
<script type="text/javascript">
function listHide(boxid){
document.getElementById(boxid).style.visibility = "hidden";
document.getElementById(boxid).style.display = "none";
}
...
So I deleted this and lo and behold, the page stopped working completely again. So I put it back in and it worked!
As I said I haven't done any real Javascript before so I don't really know the nuances of the page structure concerning the scripting environment. But this seems like a very very odd issue.
But it's one of those "how the hell did I ever figure that out."
In case someone is bored and wants to figure this out I've attached the code. I wouldn't mind knowing (for future reference) why in the world this is happening.
