Yes that is our approach too. Get it working in Firefox (using Firebug and httpfox for debugging) and you can be pretty certain it will work in Opera, Safari and Chrome also. You then try IE and (depending on how sophisticated your UI is) you usually find there are one or two nasties to code around. jQuery masks most of the foibles for you. We have found that IE8 must be used in "IE8" browser mode and "IE 8 Standards" document mode to work consistently with a jQuery based UI (as opposed to the various IE compatibility modes).
FWIW, although you can get by with "just enough javascript knowledge" to use jQuery, I still believe you really need a fairly in depth understanding to get the maximum benefit - especially to build your own widgets and plug-ins on top of the base library. Including "jQuery UI" and "themes" also gives you a much greater scope to develop a decent modern UI.
I have kept an eye on these perceived security vulnerabilities and haven't found anything alarming at all. One or two of the so-called vulnerability issues being placed at the jQuery door have nothing to do with jQuery as such - they are general potential issues with client-side scripting with or without a library like jQuery or Glow (from the BBC). Take this one for example:
http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2007-2379 This is labelled as a jQuery issue but is nothing specifically to do with jQuery at all. You might look at this and think that simply by including jQuery in your application you automatically have this vulnerability - but that would also be completely untrue. Normally, if you understand the things that you are exposing in your app, then you should be able to avoid vulnerabilities, especially if you are only using the UI enrichment aspects of the library.

Hi Jim,
I would agree with what everyone else has said on jQuery. I do recommend
that you have some understanding of Javascript - just enough to
appreciate what jQuery actually does for you.
When it comes to CSS, IE is really the fly in the ointment. But the good
news is that all of the "issues" are well documented, along with their
solutions. Most of the issues you will probably hit have to do with
layout - and any book on CSS will highlight those, along with their
solutions. Also, CSS is not something you will be constantly tweaking on
a large scale, so you should be able to get it right fairly early on.
For me, the rule is to do all my development/testing using Firefox
(because of all the great development plug-ins like Firebug and Web
Developer Toolbar) - and then check what my pages look like in IE.

In dealing with customer web pages (order entry) how are others handling browser differences?
Do you dumb the features down to a level most browser accept or code sections for different browsers? This is search & data entry & not so much point & click, & project on a skinny budget.
Depending upon whose stats (this is w3schools),
Internet Exp8 16.2% IE7 7.8% IE6 6.7% Total 30.7
Firefox 4.0 0.6% 3.6 35.2% 3.5 6.1% Total 45.8
Chrome 6.0 1.4% 5.0 15.1% 4.0 0.3% Total 17.0
Safari S5 2.6% ... 3.5
We want to set a minimum standard for browsers.
All of this will be in rpgle cgi.
