I have the following HTML:

    You can follow the .selectedIndex strategy of danielrmt, but determine the index based on the text within the option tags like this:

    $('#dropdown')[0].selectedIndex = $('#dropdown option').toArray().map(jQuery.text).indexOf('B');

    This works on the original HTML without using value attributes.

    If you are using JQuery, since the 1.6 you have to use the .prop() method :

    $('select option:nth(1)').prop("selected","selected");

    I'd iterate through the options, comparing the text to what I want to be selected, then set the selected attribute on that option. Once you find the correct one, terminate the iteration (unless you have a multiselect).

     $('#dropdown').find('option').each( function() {
      var $this = $(this);
      if ($this.text() == 'B') {
         $this.attr('selected','selected');
         return false;
      }
 });
