Filter element based on .data() key/value

Question

Say I have 4 div elements with class .navlink, which, when clicked, use .data() to set a key called \'selected\', to a value of

Answer 1

Just for the record, you can filter on data with jquery (this question is quite old, and jQuery evolved since then, so it's right to write this solution as well):

$('.navlink[data-selected="true"]');

or, better (for performance):

$('.navlink').filter('[data-selected="true"]');

or, if you want to get all the elements with data-selected set:

$('[data-selected]')

Note that this method will only work with data that was set via html-attributes. If you set or change data with the .data() call, this method will no longer work.
