Hi,
I would like to load scriptaculous.js after someone clicks on a link.
I have tried to use
<head>
<script type="text/javascript"
src="javascript/prototype.js"></script>
<script type="text/javascript">
<!--
function loadContent(file){
var head = document.getElementsByTagName(''head'').item(0)
var scriptTag = document.getElementById(''loadScript'');
if(scriptTag) head.removeChild(scriptTag);
script = document.createElement(''script'');
script.src = file;
script.type = ''text/javascript'';
script.id = ''loadScript'';
head.appendChild(script)
}
//-->
</script>
</head>
and on page
<a href="javascript: loadContent(''javascript/
scriptaculous.js'');">test</a>
but It created a lot of errors like that prototype does not exist
etc.. and i did not work.
Can you help me please? I do not want to load scriptaculous on page
load since it is quite big...

So, your link needs to run ... function loadScriptaculous() { if (typeof Scriptaculous=''undefined'') { document.write(''<script type="text/javascript" src="/scriptaculous.js"></script>''); } } -- ----- Richard Quadling Zend Certified Engineer : http://zend.com/zce.php?c=ZEND002498&r=213474731 "Standing on the shoulders of some very clever giants!" --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

Hi, thanks a lot. I could not use the php script, but I joined all js to one file and packed it by gzip and now it loads perfectly ;) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Spinoffs" group.

I now realise I only pass data around in JSON, not raw code, though an object definition could be passed I believe. So if you had a framework to handle a particular object which had code ...
