Get parent ID from div jquery

Question

I have a image inside a div when i click on the image i want it to alert me of the parent id that will be "group1"

<div id="group1">
<img class="header_logo_dis" src="test.png">
</div>

$('.header_logo_dis').click(function() {
    alert($(this).parent("div:first"));
});

Thank you,

Answer 1

How about:

alert( $(this).closest('div').attr('id') );

Answer 2

alert ($(this).parent().attr('id'));

Answer 3

Or to be extra efficient and skip jQuery altogether:

alert(this.parentNode.id);
