jQuery select elements that match class and attribute?

Question

I'm currently selecting all elements with class .follow-container, this is the code:

$('.follow-container').html('it's this one');

How do I only select elements that have the class and also the attribute onmousedown="alert()"

Answer 1

$('.follow-container[number="3"]')

Answer 2

Just to mention but you should really use a data attribute instead of an unsupported number attribute.

What about data-number="3" instead?

You could then select this using:

$('.follow-container[data-number="3"]');

If you would prefer to use your attribute you could use:

$('.follow-container[number="3"]');
