javascript - jquery datepicker - add class to first 17 days -

is there way give class first 17 days on jquery datepicker calendar?

i have tried seems add class every day...

    beforeshowday: function(date) {         (i = 0; < 17; i++) {             return [true, 'myclass'];         }         return [false, ''];     } 

edit:

i've managed following code:

beforeshowday: function (date) {      if (date <= new date().setdate(new date().getdate()+17) && date >= new date() ) {         return [true, 'myclass'];     }      return [true, ''];  } 

the problem doesn't give class todays date. ideas why?

maybe like:

beforeshowday: function(date) {    var today = new date(), maxdate;    today.sethours(0,0,0,0);    maxdate = new date().setdate(today.getdate() + 17);    if (date <= maxdate && date >= today ) {       return [true, 'myclass'];    }    return [true, '']; }
