jQuery - what is the feature of this selector rule?

I saw the following usage of jQuery selector:

$('[value=""]', event.target).remove();

I can guess the meaning of this statement is to remove the option value="" from the selector event.target.

The pattern looks like $(A, B). What kind of selector rule is used here in jQuery?

Thank you

That snippet will remove all the elements which have the empty attribute value, descendants of the event.target element.

Example, removing all the links on the stackoverflow listing page:

jQuery('a', jQuery('#question-mini-list')).remove()

See the documentation.

This code passes the context parameter, meaning that it will search only the children of the second parameter.
It's equivalent to $(event.target).find('[value=""]')
