hello… after seeing some cool AJAX tricks, decided i should go back and properly learn javascript. currently, i just know enough to take them apart and make modifications.

anyhow, i’ve always been a fan of joe burns ([htmlgoodies.com](http://htmlgoodies.com)) writing style, so i went over there to read through some of his jscript tutorials. the problem is, many of his examples dont seem to be very cross browser friendly.

\*\*anybody got any ideas on where can i find javascript tutorials that teach while keeping modern browsers and a \*“reasonable” \*amount of accessibility in mind?

thanks!

:)\*\*

I don’t run into too many browser compatibility issues with JavaScript anymore. At least not like back in the day. It may just be I avoid code that I know doesn’t work… or more likely it’s that support has just gotten better.

You may want to check out QuirksMode ([http://www.quirksmode.org/](http://www.quirksmode.org/)). I know they have a JavaScript section, I’m just not sure if it has the exact details you may be looking for. I believe I remember seeing some browser compatibility tables there.

I took a quick look around and well… most of the sites I found on JavaScript browser compatibility are old. I mean when you see charts with IE3 and 4 on them… well you know they’re out dated.

I’ll look around a bit and see if I can’t find something but otherwise, do like I did, grab a bunch of browsers and test the stuff yourself. Then keep a log of what works and doesn’t work.

Learn the language features of JavaScript first - stuff like closures, classes, basic arithmetic, string methods, and so on. Then learn the DOM, which by now is pretty cross-browser. Then you can do pretty much anything.

**hey, thanks for your replies!**  
thats the plan… go back over the basics… then get into the more current uses… if there’s no way around some of the old-school cross browser issues… then thems the breaks… but i suppose its certainly not a _bad thing_ to get re-aquainted with what they were/are…
