Newbie Javascript Issue

Apr 17 '08, 05:39 PM

Hi all - can someone please point me in the right direction. I have pages that launch their javascript components fine if the page is loaded on its own. But when the page is loaded AJAX the javascript does not fire. An example is this simple web page:

[HTML]<html>
<head>
<title></title>
</head>
<body>
<script type="text/javascript">
alert("Hello World")
</script>
</body>
</html>[/HTML]

When called on it's own, I get a "hello world" alert.

When I load this page via AJAX into a div, the alert is not displayed.

I've written many pages which are dependent upon javascript which work fine until called by AJAX. I'm guessing this is simple but I'm missing a key ingredient here.

Thanks in advance for your help.

Yes, the key ingredient is that the JavaScript won't run like that.

There's two ways, either use eval (the quick, dirty way);

or dynamically add the script to the parent page, e.g.
[code=javascript]var script = document.create Element("script ");
script.type="te xt/javascript";
script.appendCh ild(document.cr eateTextNode(th eJScode));
document.getEle mentsByTagName( "head")[0].appendChild(sc ript);[/code]
