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 means, am a master at jQuery.

Answer 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

Answer 2

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.
