Question

I am looking to select all elements of type input and select, but only if their id isn’t null.

I’ve gotten this:

$('input, select') 

for the element types and this:

$(*[id])

for not null ids. I have no idea how to combine them into:

((isSelect || isInput) && id != null)

Thanks in advance.

Answer 1

You could add the attribute selector after each element selector:

var elems = $('input[id], select[id]');

Here’s a working example.

Also note that (in browsers that support querySelectorAll, at least) this should be significantly faster than using .filter():
