A few differences between IE7 and FF3, what we discovered in coding
03 Jun 2009 Geng Wang project
There are of course more of them, but we only list which will bring
confusion to our code. Note that the current version is based on IE,
not FF, since its more vulnerable.
I don’t know how to write HTML in this blog, so i hope i can make them clear without examples.
1. Both in IE and FF, we can use the ID of a DOM object to call it. But we cannot always use ‘document.id’ to call it. In FF, document.f (f is id of a form) is undefined, but in IE, document.i (i is id of an image) and some other DOMs is undefined.
