javascript - jQuery datepicker 禁用每周除一个日期外的所有日期

Question

我想选择一个日期，假设我选择一个星期一，我只想只能在另一个日期选择器上选择星期一并禁用所有其他日期，换句话说，我想选择 7 天的间隔两个日期选择器之间。

我怎样才能实现这个目标？

我尝试过这个:

beforeShowDay: function(date) {
  console.log('beforeShowDay');
  var day = date.getDay();
  return [day != day, ''];
},

但不确定它是否应该工作或者我应该将函数放置在哪个日期选择器中。

更新:

var curday = "";
var unavailableDays = [];
var dateselected = "";

function ViewDay(date) {
    dmy = date.getDate() + "/" + (date.getMonth()+1) + "/" + date.getFullYear();
    day = date.getDay();
    if (date > dateselected) {
        if ($.inArray(day, unavailableDays) == -1) {
            return [false, "", "Unavailable"];
        } else {
            return [true, ""];
        }
    } else {
        return [false, "", "Unavailable"];
    }
}

$('#startdatesahasrara').datepicker({
    dateFormat: 'dd/mm/yy',
    minDate: 3,
    onSelect: function(e) {

        $('#enddatesahasrara').removeData("hasqtip");
        $('#enddatesahasrara').removeAttr("data-hasqtip");
        $('#enddatesahasrara').qtip("destroy", true);
        $('#enddatesahasrara').removeAttr('title');

        $('#enddatesahasrara').val('');
        unavailableDays = [];
        dateselected = new Date(e);
        curday = new Date(e).getDay();
        unavailableDays.push(curday);
        console.log('trigger');
    }
});

$("#enddatesahasrara").datepicker({
    dateFormat: 'dd/mm/yy',
    showAnim: "slideDown",
    minDate: 0,
    beforeShowDay: ViewDay
});

希望有帮助!

var curday = "";
var unavailableDays = [];
var dateselected = "";
$('.datepicker1').datepicker({
  dateFormat: 'yy-mm-dd',
  onSelect: function(dateText) {
    $('.datepicker').val('');
    unavailableDays = [];
    dateselected = new Date(dateText);
    curday = new Date(dateText).getDay();
    unavailableDays.push(curday);
  }
});

$(".datepicker").datepicker({
  dateFormat: 'yy-mm-dd',
  showAnim: "slideDown",
  minDate: 0,
  beforeShowDay: ViewDay //$.datepicker.noWeekends
});


function ViewDay(date) {
  dmy = date.getDate() + "-" + (date.getMonth() + 1) + "-" + date.getFullYear();
  day = date.getDay();
  if (date > dateselected) {
    if ($.inArray(day, unavailableDays) == -1) {
      return [false, "", "Unavailable"];
    } else {
      return [true, ""];
    }
  } else {
    return [false, "", "Unavailable"];
  }
}
