Answer 1

Change IDs and data attributes as you wish!

  <select id="selectVehicle">
       <option value="1" data-year="2011">Mazda</option>
       <option value="2" data-year="2015">Honda</option>
       <option value="3" data-year="2008">Mercedes</option>
       <option value="4" data-year="2005">Toyota</option>
  </select>

$("#selectVehicle").change(function () {
     alert($(this).find(':selected').data("year"));
});

Answer 3

This is what I came up with:

		$(document).ready(function(){
		
		$(".fc-event").each(function(){
		
			console.log(this.attributes['data'].nodeValue)	
		});
    
    });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<div id='external-events'>
			<h4>Booking</h4>
			<div class='fc-event' data='00:30:00' >30 Mins</div>
			<div class='fc-event' data='00:45:00' >45 Mins</div>
</div>

Answer 4

You could use the .attr() function:

$(this).attr('data-fullText')

or if you lowercase the attribute name:

data-fulltext="This is a span element"

then you could use the .data() function:

$(this).data('fulltext')

The .data() function expects and works only with lowercase attribute names.

Answer 5

This works for me

$('.someclass').click(function() {
    $varName = $(this).data('fulltext');
    console.log($varName);
});
