Question

Say I have an element on the page:

<div data-name='foo'>

What’s the best way to get the attribute value? Is there anything more DRY than $('[data-name]').attr('data-name') or $('[data-name]').data('name')?

Answer 1

I don’t know how do you define “DRY”…
if (x < 0) x = 1 isn’t “DRY” because you wrote x twice?

Anyway with the current DOM structure, no there is not. The selector is inefficient which is more important!

You can give the element an id, which make the code faster.

<div id='foo' data-name='foo'> </div>

…

$('#foo').data('name'); // That's more like it.
