I shall start by saying that I really don't know much at all about javascript.

I'm trying to send my xhtml as application/xhtml+xml wherever possible, which means I need well formed xml or I get lots of lovely errors.
I'm usually a validation nut, so this hasn't been a problem with most stuff. However, I have several fanlistings on my site which use a script called phpfanbase.

I've spent lots of time converting its html to xhtml, and removing lots of silly tables etc. Now the only thing stopping it from validating/being well formed is this bit of javascript:


function submitonce(theform){
//if IE 4+ or NS 6+
if (document.all||document.getElementById){
//screen thru every element in the form, and hunt down "submit" and "reset"
for (i=0;ivar tempobj=theform.elements[i]
if(tempobj.type.toLowerCase()=="submit"||tempobj.type.toLowerCase()=="reset")
//disable em
tempobj.disabled=true
}
}
}


Can anyone explain what this does? If it's nothing too important then I'm just going to delete it I think.
thanks :)
