Grabbing text from a span tag

Question

I have some code for Javascript using jQuery, and I've been wondering how to fix an element of it.

var dataGiven = +$("span.cost-in-usd:first-child").text();

However, the span tag is:

<span class="cost-in-usd" data-se="product-usd-value">42</span>

Is there a way of modifying my code in order for it to recognise data-se?

Answer 1

The following will return the value of attribute

 $('.cost-in-usd').attr('data-se');

Answer 2

Yes, use data.

   var datase = $('.cost-in-usd').data('se');
