    /* then do something here */
}

I, by no mean

Simply use:

Pure js approach:

var elem = document.getElementsByClassName('parent');
alert(elem[0].hasAttribute('id'));

Answer 3

You can do

document.getElementById(id) or 
$(id).length > 0

Answer 4

You can using the following code:

   if($(".parent a").attr('id')){

      //do something
   }


   $(".parent a").each(function(i,e){
       if($(e).attr('id')){
          //do something and check
          //if you want to break the each
          //return false;
       }
   });

The same question is you can find here: how to check if div has id or not?

Answer 5

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.

Answer 6

You can use each() function to evalute all a tags and bind click to that specific element you clicked on. Then throw some logic with an if statement.

See fiddle here.

$('a').each(function() {
    $(this).click(function() {
        var el= $(this).attr('id');
        if (el === 'notme') {
            // do nothing or something else
        } else {
            $('p').toggle();
        }
    });
});
