i start learning jquery few days ago, and i like it very much. but now i have a problem, that can't solve alone.

i have two selects

<select id="select1">
  <option value="1">1day</option>
  <option value="2">2day</option>
  <option value="3">3day</option>
</select>

<select id="select2">
  <option value="1">1day</option>
  <option value="2">2day</option>
  <option value="3">3day</option>
</select>

i need to set #select2 the same value with #select1, when #select1 changes i've red some questions about select tag here, but i need to set "selected" attribute to that option, which have the same value. how can i do it?

Thanks
