is there anyway to have a jquery UI date picker only allow saturdays?

问题

I am using a jquery ui datepicker. I want to add some validation so it only allows people to choose Saturdays instead of any date.

I could validate after the fact but thought it would be slicker to have the datepicker do the upfront validation by only enabling Saturday dates.

回答1:

$("#test").datepicker(
    {
        beforeShowDay: function(date){
          if(date.getDay() == 6){
                return [true];
            } else {
                return [false];
            }
        }
    }
);
