This should do the job:

$(document).ready(function() {

  $('#langs li').click(function() {
    alert($(this).attr('data-val'));
  });
});

Original answer - 2011

$('li').click(function () {
    alert($(this).data('val'));
});

See DEMO.

Update - 2017

Keep in mind that if you want to use the ES6 arrow function syntax, you cannot use this and you need to use e.currentTarget instead, where e is the event object passed as the first parameter to the event handler:

$('li').click(e => alert($(e.currentTarget).data('val')));
