(editor's note: As many of us have learned, JavaScript can be a bit of a problem if you're trying to develop something with cross-browser compatibility. This chart allows you to look up objects and see which browsers they are compatible with. Good luck.)

This is a prety long list so we have split it up over several pages. They are still a bit slow to load due to their size.

What works in which browser and what doesn't.

JavaScript Weirdness

by Ciff Wootton

Here's a list of the percentage of JavaScript features that work in each of the popular browsers. Sadly, it looks like only about 31% of the features work with both 3.0 and above browsers. I know site developers who have decided to simply not use JavaScript at all rather than mess with the compatibility issues.

IE 3 & 4 243 31.68% Nav 3 & 4 373 48.63% IE4 & NAV 4 425 55.41% All 4 browsers 240 31.29% A further caveat: This suggests areas that you should check rather than just go on my say so. Some features could get implemented at intermediate releases such as 4.04 where they weren't available at 4.03 or might be available only on certain platforms. So we are simplifying things a little when we talk about Nav 3 vs. Nav 4. There is a Web Standards pressure group that is trying to get some groundswell of public opinion going to make Microsoft and Netscape toe the line and at least support the W3C and other published standards. They are at http://www.webstandards.org/ and are called 'The Web Standards Project'.
