This was palmToFace obvious once it occoured to me but due to the lack of Google results on the topic:
$("select#idOfElement").attr("selectedIndex")
Update, even better!
//see Dan's comment
$("#idOfElement").attr("selectedIndex")

Using JQuery to find the Selected Index of a Select Element

Tuesday, April 28th, 2009A nice article on improving your jquery codez:
JQuery and Building HTML Elements Fast
Monday, April 13th, 2009A co-worker recently shared an article by Josh Powell about how to use the jquery append() function much more efficiently. Thank goodness because today my JS requirements changed and I now had to build some html on keypress instead of onchange. The codez I was using was way too slow for this sort of mischief.
My take on the article is thus: Don’t create and append nested elements to nested elements to nested elements into your document. Instead build the HTML in a string and then append just one time. The article explains it quite well so I won’t rehash the whole thing. Check it out:

I file that one under “stuff I didn’t know I needed to know until days after I learned it”.
I like cfuniform!

Add Cookies to Firebug
Wednesday, February 11th, 2009
If I were to make a list of useful things Firebug would be right up there with seat belts, calculators, sun screen, and forks. Today I found myself chasing a piece of data while tracking down an elusive bug in unfamiliar code when <cfcookie> stopped me dead in my tracks.
First stop with any problem is Google (add that to the list of useful things) which provided a list of hundreds of cookie tracking tools. After much deliberation I wound up selecting “Firecookie 0.7″ by Jan Odvarko.
Thus far I have to say I like it. Firecookie fits nicely into Firebug 1.3.1 without making me think about where to go find it. Cookie events get logged to console so I can see when cookies are created and deleted. The cookie tab lets me see all relevant cookies, add my own cookies, or delete current cookies. Just what I needed.

Much thanks to Jan Odvarko!
What jQuery plug-in can you not live without?
Tuesday, February 3rd, 2009jQuery UI is a HUGE timesaver when you need a solution to a common interface problem. Plug-ins make for easy addition of usability features like table sorting, searching, autocomplete, drag n drop, and tons more!
Picking out a jQuery plug-in can be a pain. Several different plug-ins to do the same job, which one do you choose?
Here are the tests that a plug-in has to pass to make it into my developer playbook:
- Is it easy to use? It had better be, that is why I’m using jQuery in the first place!
- Is it easy to read the syntax? My code does not need any help being confusing. As Brain C. would say: “don’t make me think!”
- Are other developers using it? Peer support is very important in jQuery and you can’t get much help from your peers if they don’t use the plug-in.
- Has it been around for a while? The latest and greatest is not so great when it’s unheard of in 6 months
- Has it been updated recently? If the author/maintainer doesn’t care about the plug-in anymore, why should I?
- Is it > version 1.0? I don’t have time to beta test your plug-in right now. Maybe later?
Gahh… thats a lot of work to check all that stuff out for 10 different plugins. I thought jQuery made everything easy.
Drop me a comment! which jQuery plug-ins do use most frequently?
