Question

I would like to get an array of the values from the data-val attributes of .my-li elements

<ul id="stuff">
<li class='my-li' data-val='1'>
<li class='my-li' data-val='2'>
<li class='my-li' data-val='3'>
<li class='my-li' data-val='4'>
<li class='my-li' data-val='5'>
<ul>

here the result should be [1,2,3,4,5];

anybody knows a good way of doing this ?

Answer 1

Try:

var foo = $('#stuff .my-li').map(function () {
  return $(this).data('val');
});
