Using Javascript libraries + Ajax

[themasum]

Can anyone help me please.I want to use javascript Scriptaculous library. I found the information to load Scriptaculous in https://dev.virtuemart.net/cb/wiki/1368

where it says to follow vmCommonHTML::loadScriptaculous(); but this not working, then I search the source in joomla directory administrator\components\com_virtuemart\classes\htmlTools.class.php and there no function defined loadScriptaculous() in vmCommonHTML class.Is it mistake or I have to try another way.
