jQuery if Element has an ID?

Question

How would I select elements that have any ID? For example:

if ($(\".parent a\").hasId()) {
    /* then do something here */
}

I, by no mean

I seemed to have been able to solve it with:

if( $('your-selector-here').attr('id') === undefined){
    console.log( 'has no ID' )
}
