Discussion on:

jQuery: How to get objects by ID, Class, Tag, and Attribute

Hi,
I'm not really good in english, but you don't "Get objects by attribute", you changed some attribute of an element, nothing else...

Getting an element by attribute looks like that :
$('img[class]');
or with a value :
$('img[class="image"]');
or more difficult :
$('img[class$="align"]');

Or with filter function :
$('img').filter('[class="image"]');

Thank you.
