How to pass/get the data attribute in the following situation?

Question

JavaScript

Friends, tell me how to pass the data-rat attribute in this case:

<div  class='dop' data-rat='8.50'></div>

$('div.dop').myRat({'tekr': $(this).data('rat') }); - не передается в функцию
$('div.dop').myRat({'tekr': 888 }); - передается

Thank you very much in advance)

Answer 1

Because this at the time of code execution is unlikely to point to div.pop.

var $pop = $('div.dop');
$pop.myRat({'tekr': $pop.data('rat') });

Answer 2

Your this link is completely wrong, and $.fn.data has a different purpose than getting data attributes. Read the feature documentation before using it.
