Of course not: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd";> <html> <head><title></title></head> <body foo="bar"> <script type="text/javascript"> // writes "CSS1Compat" (would print "BackCompat" in Quirks) document.write(document.compatMode); </script> </body> </html> > > > > > > > It is indeed useful.

Some of them are already present in modern browsers (e.g. `document.getElementsByClassName` or `document.querySelector`). Nevertheless, try not to use custom attributes, unless you want to run into troubles later on (e.g. remember that the entire DOM in IE is implemented in such way that there's no distinction between element attributes and properties). -- kangax --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.
