One subtle point I think I ve discovered about the top voted answers is that even though they correctly change the selected value  they do not update the  element that the user sees  only when they click the widget will they see a check next to the updated element    Chaining a  change   call to the end will also update the UI widget as well       target   val     target option first   val    change       Note that I noticed this while using jQuery Mobile and a  box on Chrome desktop  so this may not be the case everywhere
