title: jquery get only all html elements with ids
body: <p>I have a div with many many html elements like other divs, trs, tds, tables etc</p>
  
  <p>Is it possible to get all the elements which have an id?
  I know asking <code>$("#test")</code> will give me the specific element with this id</p>
  
  <p>but is it possible to get <code>find("#")</code> or something like this?!</p>
