检查日期是否在过去Javascript [英] Check if date is in the past Javascript

问题描述

所有，
我正在使用jQuery UI作为日期选择器。我试图用javascript检查，但用户输入的日期是过去的。这是我的表单代码：

All, I'm using the jQuery UI for the date picker. I'm trying to check with javascript though that the date the user has entered is in the past. Here is my form code:

<input type="text" id="datepicker" name="event_date" class="datepicker">

然后，如何使用Javascript检查这个，以确保它不是过去的日期？谢谢

Then how would I check this with Javascript to make sure it isn't a date in the past? Thanks

推荐答案

var selectedDate = $('#datepicker').datepicker('getDate');
var now = new Date();
now.setHours(0,0,0,0);
if (selectedDate < now) {
  // selected date is in the past
}
