I just implemented such a solution a couple of weeks ago

Here is a very good post that will explain all.


So I have a field called "Data Classification":

var dataClsField = $('select[title="Data Classification"]');

I was trying to set this field with the value of another dropdown called "DataClass" that I got using this code:

var clsFieldValue = $('select[id*="DataClass"] option:selected').val();

For some crazy reason, I had to do both of these options to get my first field to set right:

dataClsField.find('option[value="'+clsFieldValue+'"]').prop('selected', true);

Note: This was with 2 dropdowns with less than 20 items in each. I believe the only difference, jQuery-wise, when it goes over that, is that "select" becomes "input" on your selector.
