title: jquery select the option list with dynamic id
body: <p>I have an option list with an id that could sometimes be one of these:</p>
  
  <pre><code>edit-panes-billing-billing-zone
  edit-panes-billing-billing-zone--1
  edit-panes-billing-billing-zone--2
  edit-panes-billing-billing-zone--3
  edit-panes-billing-billing-zone--4
  </code></pre>
  
  <p>There is only one select element at a time.</p>
  
  <p>Is it possible to select the option list dynamically with jQuery?<br>
  This is what I've tried, but it's not working:</p>
  
  <pre><code>$("select[id^='edit-panes-billing-billing-zone--']").each(function() {
      alert('test'):              
  }
  </code></pre>
