Q: datepicker, jquery I have a datepicker (jquery)

$("#datepicker").datepicker({
});

I want to colorize(highlight)  some days in this datepicker.  And these days i'd like to get from some array !!!!
I dont know, something like this:

$("#datepicker").datepicker({
  highlight:['09/16/2009', 09/12/2009,
  08/16/2009 ....]  });

Help me please
Thanks a lot !!! 

A: Try using the beforeShowDay function of the datepicker. This fires before rendering each day in the picker. Inside the funcion you check if the current date is in an array of special dates. If it is then you can return an array where the second element is the name of the css class you want rendered on each td.
Demo here
  var someSpecialdates = [1, 5, 12, 21, 27, 30]; 

    $("#datepicker").datepicker({ 
      beforeShowDay: function(dt) { 
        var d = dt.getDate(); 
        return ( $.inArray(d, someSpecialdates ) === -1 ) ? [true,""] :
                                                            [true, "specialDateCSSClass"]; 
      }
    });
