Finally Improving My jQuery

Taking a break from rails tonight to go through the peepcode video on jQuery. The advice I had from a pal is that jQuery is easy and separate enough from javascript that it can be learned by itself. I’m not certain I agree just right now, but it’s definitely a big eye-opener.

The big take home point for beginners here seems to be learn the following:

$()

is a wrapper function. It serves mainly to take an argument, and make a jquery methods available on that argument. For example:

$("#someId")

will wrap the someId element on a page inside jQuery and make jQuery methods available:

$("#someId").fadeOut

The other thing is that you’re going to be doing a lot of finding elements, so learn your bloody selectors! The jQuery documentation on selectors contains a bunch of jQuery specific stuff. Otherwise, I’ve been mostly learning them via writing selenium automation tests at work. 

I have a ton of documentation to research on test the rails view for a talk I’m leading tomorrow. Wish me luck!
