Introducing Bindler

Rails. Hobos. Bundler. Bindles.

I awoke one day last week with this comic idea percolating in my brain. Too bad I'm lousy at drawing.

Chaining jQuery Pseudoselectors

I just finished a very simple Javascript tweak to an app. Here was the requirement: "When the user opens our sign-in modal, we should focus the on the first input." Whatever code I wrote, I would put it a callback when the modal was finished opening.

This was my first solution: target the id of the first input, and focus on it.


But I didn't like that, because it's not very flexible. What if we add another input to the beginning of the form? We'd have to change the javascript, too.

After a little tinkering with jQuery's psuedoselectors, I came up with this:


Besides being more flexible to future changes, I think this is still pretty readable: select the first input that isn't hidden and focus on it.
