Question

So I just need a reminder,

Every element can only have 1 id, but multiple classes are possible,

But what if I would like to have 2 ways to uniquely identify an object without classes?

I cant remember the name of it, something like Tagname, that can be used in addition to ID.

And how would you identify this object in jQuery?

For classes it is: $(‘.class’), for ID’s it is $(‘#id’) but what about this thing that I am vaguely describing?

You might be thinking of GetElementsByTagName() but that will return a collection:

You can use arbitrary attributes in any modern browser (jQuery does this behind the scenes). So you can put whatever attribute you want on an element and locate it using a jQuery attribute selector (as @Dave pointed out in his answer).

<div myAttribute="foo"></div>

<script>

var element = $("div[myAttribute='foo']"); // matches all divs with "myAttribute" set

</script>
