You can override any $.ajax() parameter except: async, complete, error, statusCode, success (ie: parameters that effect control flow) If ajaxOpts is a function the first argument is the text that the user has typed and the second argument is the current value of the AutoComplete widget. The function should return an object to pass to $.ajax().
