title: With jquery autocomplete widget, how to populate the input value after a selection with my own data
body: <p>In my form text input bar, the json returned by the autocomplete widget will be, [{id = 1,lable="lable1"},......]</p>
  
  <pre><code>[{id = 1,label="label1"},{id = 2, label="label2"},......]
  </code></pre>
  
  <p>and I want the input box display value to be "label" which works as default, but I want to the input value to be "id" when I submit the form..</p>
  
  <p>Many thanks!</p>
