select Option based on value

select Option based on value

Hi, I would like to select the value of select option dynamically using jquery. I am calling service to get country name, based on country name, i need to set that country as selected.  I will get country in full name from service( like "Canada") and not in two letters.
 
<select>
  <option value="US" text="United states" />
<option value="CA" text="Canada"/>
<option value="Mx" text="Mexico" />
</select>
 
Could anyone help me on this?
