javascript - 如何在 jQuery datepicker 中每周随机启用一天

Question

目前我在日期选择器中仅显示接下来的 60 天。我试图每周只随机启用一天。我不知道该怎么做。

  $( "#visit" ).datepicker({
   beforeShowDay: $.datepicker.noWeekends,
   minDate: 0,
   maxDate:60
   });

您可以编写自定义函数来禁用除一周中的某一天之外的所有日期，和下面的代码

$(function(){

    $("#visit").datepicker({
         beforeShowDay: available,
         minDate: 0,
         maxDate:60
    });
    
      //get random value to select date
      var random = Math.floor(Math.random() * 5) + 4;
      //console.log(random);
    function available(date) {
      var day = date.getDay();
      //disable weekends
      if(day==6 || day==0) {
        return [false,"","unAvailable"];
      }
      
      var dt = date.getDate();
           
      if (dt % random ==0) {
        return [true, "","Available"];
      } else {
        return [false,"","unAvailable"];
      }
    }

});
