Question

我有一个jquery datepicker，它通过局部视图在ajax请求中动态添加。我必须在选择日期后进行js检查，所以我想出了这个 -

$（document）.ready（function（）{

    $(document).on('change', 'input[name="ReportDate"]', function () {
        if ($(this).attr('data-isDccmAndReady') == 'True') {

            var d = new Date();
            var currentDate = (d.getMonth() + 1) + "/" + +d.getDate() + "/" + d.getFullYear();

            var dateSelected = $(this).val();

            if (new Date(dateSelected) > new Date(currentDate)) {
                var answer = confirm("The contract has been already reported, are you sure you wish to continue?");

                if (answer) {
                    return true;
                } else {
                 //this is correctly resetting the value
                    $(this).val($(this).attr('data-originalReportDateVal'));//$(this).val() gives the old and the correct value.  
                    return false;
                }
            }
        }

        return false;
    });
});
 </script>

当您在确认框中选择取消时，datepicker值不会恢复为html中的旧值或不刷新。

http://api.jqueryui.com/datepicker/#method-refresh

       if (new Date(dateSelected) > new Date(currentDate)) {
            var answer = confirm("The contract has been already reported, are you sure you wish to continue?");

            if (answer) {
                return true;
            } else {
                $(this).val($(this).attr('data-originalReportDateVal'));
                $(this).datepicker( "refresh" ); // <-- Try this (or with the right datepicker selector)
                return false;
            }
        }

这适用于解决方法

var id = $（this）.attr（'id'）;

$（'＃'+ id）.val（$（this）.attr（'data-originalReportDateVal'））;

我不确定为什么它不能直接与

一起使用

$（本）.VAL（$（本）.attr（ '数据originalReportDateVal'））;

在jquery上确认为false后，输入框没有刷新
