I assume you are looking for a way to select multiple <th> elements based on one or more ids. You can simply chain selectors like this:

$('th#x, th#y, th#z'); // will return 3 elements, if they exist

Original answer:

No.

jQuery.attr() is used to set valid properties on HTML objects.

If you want to store arbitrary data linked to a HTML object, use jQuery.data().

[EDIT] the question has been modified to clarify what he wants, so I've removed the inapplicable parts of my answer...

JQuery (and CSS) allows you to use multiple selectors together:

For example:

$('[id=x], [id=y], [id=z]')

...will select all elements in your page with either of your possible id values.

Alternatively, if you only want to find them within $(this), you would use the find() method:

$(this).find('[id=x], [id=y], [id=z]')

Hope that answers you're question.

Depending on the values you're searching for, you may also be interested in more advanced attribute selectors. For example, if your x, y and z options all begin with the same string, you could use the attribute prefix selector:

$('[id|=prefix]')

or if they all contain a particular word:

$('[id~=word]')

there are a number of possible options; that should give you a start, but see the JQuery manual for more information: http://api.jquery.com/category/selectors/

Would this work for your needs - replace { with "?

$(this).attr("alt","1,2,3")
