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 */
}

You can use jQuery's .is() function.

if ( $(".parent a").is("#idSelector") ) {

//Do stuff

}

It will return true if the parent anchor has #idSelector id.
