Markup Validation Error: "Duplicate ID" #HTML5

Updated July 12, 2013 ‚óŹ 1,039 views

Another lesson learned while building this website. After doing a markup validation, I get a couple of "Duplicate ID" errors at the frontpage. Since the content list is generated from the database, the same element ID was generated on each list.

<a href="javascript:void(0);" id="likeItem" data-index="0">like</a>

To resolve the duplicate ID error, I removed the element ID and used data attribute instead.

<a href="javascript:void(0);" data-action="like" data-index="0">like</a>

<script type=\"text/javascript\">
jQuery(function($) {



I just put my site on validator... damn... I see the same errors. Thanks for the tip.
