Setting new value for an attribute using jQuery

Question

I am trying to set a new vale of a custom attribute of a div using attr(). I found out it can be done using .attr( attributeName, value ), but when I try it it\

Answer 1

It is working you have to check attr after assigning value

LiveDemo

$('#amount').attr( 'datamin','1000');

alert($('#amount').attr( 'datamin'));​

Answer 2

Works fine for me

See example here. http://jsfiddle.net/blowsie/c6VAy/

Make sure your jquery is inside $(document).ready function or similar.

Also you can improve your code by using jquery data

$('#amount').data('min','1000');

<div id="amount" data-min=""></div>
