How to get the closest element id attribute

问题:

I am trying to find the closest element that has id attribute and get the id. The element could be <p>, <div> or other elements.

I have tried

element=$('#test').closest('div[id]').attr('id');

but it only get the id if the element is a div. I want to be more universal. Are there anyways to do this? Thanks so much!

You can get rid of the div entirely and look for all elements that have an id attribute:

$('#test').closest('[id]').attr('id');
