Question

我使用的功能成功计算并且（应该成功）返回星期二的日期，如果今天是星期二，星期三，如果是星期三，如果它是今天的某一天它应该在下周二回来。此函数用于将此日期放入datepicker输入的默认值。我已经验证该功能实际上确实计算了正确的使用日期。但是，将返回值传递给选择器的参数时，输入对象中不会显示日期。

我尝试将字符串和数字输入到选择器函数的第二个参数而不是setDate（）中，但它仍然没有显示任何内容。

我相信这就是你所需要的。请记住将函数调用保留在同一文档加载函数中，即$（document.ready）。

    <script type="text/javascript">   
        $(document).ready(function() {
            $( ".datepicker" ).datepicker({
                minDate:'0',
                changeMonth:true,
                changeYear:true,
                beforeShowDay: function(dt)
                  {
                      return [dt.getDay() === 2 || dt.getDay() === 3, ""];
                  }
            });

            $('input.timepicker').timepicker({
                timeFormat: 'h:mm p',
                interval: 90,
                minTime: '9',
                maxTime: '10:30am',
                defaultTime: '9',
                startTime: '9:00',
                dynamic: false,
                dropdown: true,
                scrollbar: false                
            });

            function setDate() {
                var today = moment().isoWeekday(); //or just = new Date().getDay();
                var timestamp;
                if (today <= 2) {
                    timestamp = moment().isoWeekday(2);
                } else if (today === 3) {
                    timestamp = moment().isoWeekday(3);
                } else {
                    timestamp = moment().add(1, 'weeks').isoWeekday(2);
                }
                return new Date(timestamp);
            }

            $('.datepicker').datepicker("setDate", setDate());          
        });

        // function moment().isoWeekday is from Momentjs script source above.
        // to automatically set the date to the next tuesday or wednesday if not already one of those days.

        // Problem occurs here: it's like setDate() wont' give datepicker something it can display.     
    </script>
