How to set data attributes in HTML elements?

0 votes
I have a div with an attribute data-myval = "10". I want to update its value; wouldn't it change if I use div.data('myval',20)? Do I need to use div.attr('data-myval','20') only?

Am I getting confused between HTML5 and jQuery? Please advise. Thanks!

Updated div.data('myval')=20 to div.data('myval',20), but still the HTML is not updating.

Hello @kartik,

HTML

<div id="mydiv" data-myval="10"></div>

JS

var a = $('#mydiv').data('myval'); //getter

$('#mydiv').data('myval',20); //setter

Hope it helps!!

Thank you!!
