How to get, set and select elements with data attributes?

Question

I\'m having some trouble with data-attributes, I can\'t get anything to work for some reason so I must be doing something wrong:

Set:

$(\'#element\')         


        

Answer 1

// Set
$('#element').attr('data-value', 'value');
// Get
var value = $('#element').attr('data-value');
// Select
var elem = $('#element[data-value = "' +value+ '"]');
