jQuery if Element has an ID?

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

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

I, by no means, am a master at jQuery.

Solution 1:

Like this:

var $aWithId = $('.parent a[id]');

Following OP's comment, test it like this:

if($aWithId.length) //or without using variable: if ($('.parent a[id]').length)

Will return all anchor tags inside elements with class parent which have an attribute ID specified

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.
