[Typo3-dev] add bodytag-params through own ext

[Ingo Schommer]

hi there!

i want to add an onload-javascript to a page's bodytag - through my 
extension-code.

i'm aware of the fact that one can influence the bodytag via TS and 
templates, but how does it work in php?

i found something like:
$GLOBALS['TSFE']->JSeventFuncCalls["onload"]
but couldn't figure out how to use it.

any ideas?
