如何按时间禁用当前日期

Question

我在我的网站上使用了输入日期类型。我想按时间禁用当前日期。

例如

12:00:00 PM当前日期后2018-04-16禁用。

我尝试了以下代码：

<!-- disable past date -->
$(function() {
  var dtToday = new Date();
  var month = dtToday.getMonth() + 1;
  var day = dtToday.getDate();
  var year = dtToday.getFullYear();
  if (month < 10)
    month = '0' + month.toString();
  if (day < 10)
    day = '0' + day.toString();
  var maxDate = year + '-' + month + '-' + day;
  //console.log(maxDate);
  $('#demo_date').attr('min', maxDate);
  $('#demo_date').attr('max', '2018-04-29');
});
<!-- disable past date -->
<!-- disable date by time -->
$(document).ready(function() {
  var time = new Date().toLocaleTimeString();
  if (time <= '12:00:00 PM') {
    // code for disable demo_date
  }
});
<!-- disable date by time -->

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<input placeholder="Select Date" class="textbox-n" type="text" name="demo_date" onfocus="(this.type='date')" id="demo_date">

好的，

你明白了。我在这里为您制作了一个演示，您将无法在中午 12：00 之后选择当前日期。 干杯....

$(function() {
  var dtToday = new Date();
  var month = dtToday.getMonth() + 1;
  var day = dtToday.getDate();
  var year = dtToday.getFullYear();
 
 
  if (month < 10)
    month = '0' + month.toString();
  if (day < 10)
    day = '0' + day.toString();
  var maxDate = year + '-' + month + '-' + day;
  //console.log(maxDate);
 
   var time = new Date().toLocaleTimeString();
  if (time >= '12:00:00 PM') {
 day = day+1
 maxDate = year + '-' + month + '-' + day;
    // code for disable demo_date
  }
 
  
  
  $('#demo_date').attr('min', maxDate);
  $('#demo_date').attr('max', '2018-04-29');
});
<!-- disable past date -->
<!-- disable date by time -->
$(document).ready(function() {
 
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input placeholder="Select Date" class="textbox-n" type="text" name="demo_date" onfocus="(this.type='date')" id="demo_date">

Answer 2

在浏览器控制台中通过以下结果：

>> var time = new Date().toLocaleTimeString();
undefined
>> time
"11:27:28 AM"
>> time <= '12:00:00 PM'
true

代码工作正常。但是你应该定义表达式的另一部分。您应该定义：

if( time >= some_date_value && time <= some_date_value ) 
{
    // code for disable demo_date
}
