[jQuery] document.my_chart swf object


hi there,
i run a swf chart system on a website,
id like to access the swf from javascript
the following is working:
chart=document.my_chart; if i alert this its an HTML
EMBED OBJECT
chart.Update_XML( xml, spinning_wheel, mode ) ..... this will caue
the swf to realod data
BUT id like to make it dynamic with a function where i put both xml
url and the flash name
eg. updateChart(xmlurl, objectid)
so =>
chart= $(objectid) ........... will return just an html object ....
chartUpdate ... fails
chart= document.all[objectid] ..... FAILS in firefox
chart= document.obectid or document[objectid] fails also to return an
object ....
