Question

This submits on FF, but not on Chrome. Any suggestions?

<form action="/test" method="post" onchange="this.submit();">
   <select>
      <option value="f">f</option>
      <option value="g">g</option>
   </select>
</form>

Answer 1

<form action="/test" method="post" >
   <select name="select" onchange="this.form.submit();">
      <option value="f">f</option>
      <option value="g">g</option>
   </select>
</form>

the onchange should be on the select tag. and it is a good idea to give it a name so you can retrieve the value on the server side.
