title: Selecting input element with jQuery in CKEditor
body: <p>Okay, this one is driving me crazy - I just don't understand why this is so difficult.</p>
  
  <p>I have created an CKEditor and added my own tab to the images dialogue. In this new tab users can select an image URL from a list.</p>
  
  <p>I would like to set the image url box (a standard input box on the first tab) from this information. Normally I could select this through an ID or class but CKEditor gives every input a different ID each time.</p>
  
  <p>Is there an easy way to select other elements in the dialogue, as reading the stuff here and online just doesn't seem to make sense. </p>
  
  <p>(why couldn't everything just had a nice id like "#image_input_1_1", which would mean the image tab, input 1, CKEditor instance 1, it would be so much easier...)</p>
