How to select element which doesn't has Id attribute?

Question

I have two textarea and one of them has id attribute and other one doesn't has. Something like this:

<textarea> </textarea>
<textarea id = 'idname'> </textarea>

Now I need to select first textarea, How can I do that?

Answer 1

You could combine the :not() pseudo-class and the [id] attribute selector in order to negate elements with an id attribute:

textarea:not([id]) {}

document.querySelectorAll('textarea:not([id])');

$('textarea:not([id])');

Basic Example:

textarea:not([id]) {
  width: 100%;
}

<textarea></textarea>
<textarea id='idname'></textarea>

Answer 2

As you also don't mind a jQuery answer:

$('textarea:not([id])');

or

$('textarea').not('[id]');

Update:

For a specific name:

$('textarea[name="somename"]');
