如何允许在当前日期之前选择最多1周的过去日期。 [英] How to allow to select a past date up to 1 week before current date.

问题描述

您好，

请帮助从日历扩展器中选择当前日期和当前日期前一周的过去日期。

我的代码如下

Hello,
Please help to select the past date up to 1 week from current date and current date from a calendar extender.
My code is as follows

<script type="text/javascript" language="javascript">
     function checkDate(sender, args) {
         var toDate = new Date();
         toDate.setMinutes(0);
         toDate.setSeconds(0);
         toDate.setHours(0);
         toDate.setMilliseconds(0);
         if (sender._selectedDate < toDate) {
             alert("You cannot select past date more than 1 week!");
             sender._selectedDate = toDate;
             // set the date back to the current date
             sender._textbox.set_Value(sender._selectedDate.format(sender._format))
         }
     }
</script>

推荐答案

TimeSpan diff = senderDate- DateTime.Today;
if (diff.Days > 7) 
 {
             alert("You cannot select past date more than 1 week!");

}

}
