Add data attribute to all images under a class

Question

I'm using a lightbox that requires a specific tag inside the link. I don't really want to edit every post so I'm trying to do this automatically using jquery.

HTML

<div class="wrapper">
   <a href="imagelink.png">Image</a>
</div>

JS

  $(document).ready(function() {

// Scan classes
$('.wrapper a').each(function(){

    // Apply tag
    $(this).parent().attr('data-lity');

});
});

Result should be

<div class="wrapper">
   <a href="imagelink.png" data-lity>Image</a>
</div>

Answer 1

script

$('.wrapper a').attr('data-lity', '');

You don't need to iterate. Jquery does it for you. Just set the attribute.

Hope it helps. Cheers!

Answer 2

This will do a trick

Jquery

$(document).ready(function() {

    // Scan the webpage for all class names of 'thumb' that is seen.

    $('.wrapper a').attr('data-lity', '');

});
