I this select box :

<select id="owner_select">
  <option value="1">Hasan</option>
  <option value="5">aUser1</option>
  <option value="7">aUser2</option>
  <option value="8">aUser3</option>
</select>

I want to make an option selected, but I want it to be according the ID of the user in this list not the index, so I set the value of each option to the user ID.

How could I make one this options selected when I know just the ID, for example I got ID=5 so I want aUser1 to be selected.
