Question

当页面第一次加载下面提到的日历控件不起作用时。但是当我重新加载页面时，它正常工作。我可以解决这个奇怪的问题吗？

带有js代码的

.aspx文件

         $(document).ready(function () {

                    var initMethod = function () {

                            multiDatesPickerBinding();
                        };

                        initMethod(); //when page loads for first time

    var multiDatesPickerBinding = function () {
                        $('.button-set').buttonset();

                        $(".datePicker").each(function () {
                            var target = $(this);
                            target.datepicker({ showAnim: '', changeMonth: true, minDate: target.data('min'), changeYear: true, dateFormat: 'm/d/yy', yearRange: 'c-20:c+10' });

                        $.datepicker._getDate = function (inst) {
                            var startDate = (!inst.currentYear || (inst.input && inst.input.value == '') ? null :

将您的函数定义multiDatesPickerBinding移到DOM ready函数之外，您可能没问题。告诉你加载页面时会发生什么（ctrl + f5）...在加载浏览器时，将函数定义存储在DOM树或内存中。完成后，它会按顺序开始执行。

在你的情况下，它会在加载时绑定：

$
dom ready

实际应该做的事情是：

$
multiDatesPickerBinding
dom ready

页面重新加载问题
