如何在 JQuery Datepicker 中禁用以前的日期

Question

我开始制作一个 JQuery 日历，它是关于为事件选择约会的，我想禁用当前日期之前的日期。我还想为可用日期添加 #f48024 橙色，以更清楚地表明它们仍然可用。

我用 minDate 试过了，但到目前为止还没有用。

我的问题是如何禁用当前日期之前的日期？

编辑：我添加了以下代码使其成为可能，但它复制了日历，我不知道为什么。

$(document).ready(function(){
   $("#example-popover-2") .datepicker({
    minDate:0,
   })
   }
   )

body {
  background: #20262E;
  padding: 20px;
  font-family: Helvetica;
}


.popover
{
  left: 5% !important;
  top: 120% !important;
}


.btn 
{
    margin: 1%;
}


#banner-message {
  background: #fff;
  border-radius: 4px;
  padding: 20px;
  font-size: 25px;
  text-align: center;
  transition: all 0.2s;
  margin: 0 auto;
  width: 300px;
}

button {
  background: #0084ff;
  border: none;
  border-radius: 5px;
  padding: 8px 14px;
  font-size: 15px;
  color: #fff;
}

#banner-message.alt {
  background: #0084ff;
  color: #fff;
  margin-top: 40px;
  width: 200px;
}

#banner-message.alt button {
  background: #fff;
  color: #000;
}


.popover button{
  background: #f48024;
}

.popover button:hover{
  background:#fcb67c;
}

.popover button:focus{
  background: #052049;
}

.popover button:focus:active{
  background: #052049;
}

.arrow {
  
  visibility: hidden;
}

.ui-state-highlight, .ui-widget-content .ui-state-highlight, .ui-widget-header .ui-state-highlight {
  border: 1px solid #dad55e;
  background: #fffa90;
  color: #777620;
}

// I added this part to the code but this duplicates the calendar.

Answer 1

你能看看有没有minDateTime和maxDateTime可用吗？类似于：

    let minDateTime = new Date(someDateInThePast);
    let maxDateTime = new Date(someDateInTheFuture);
    $(".date-picker-2").datepicker({
        minDateTime: minDateTime,
        maxDateTime: maxDateTime,
        onSelect: function (dateText) {
            $('#example-popover-2-title').html('<b>Available Appointments</b>');
            var html = '<button  class="btn btn-success">8:00 am – 9:00 am</button><br><button  class="btn btn-success">10:00 am – 12:00 pm</button><br><button  class="btn btn-success">12:00 pm – 2:00 pm</button>';
            $('#example-popover-2-content').html('Available times <strong>' + dateText + '</strong><br>' + html);
            $('.date-picker-2').popover('show');
        }

    });

body {
  background: #20262E;
  padding: 20px;
  font-family: Helvetica;
}


.popover
{
  left: 5% !important;
  top: 120% !important;
}


.btn 
{
    margin: 1%;
}


#banner-message {
  background: #fff;
  border-radius: 4px;
  padding: 20px;
  font-size: 25px;
  text-align: center;
  transition: all 0.2s;
  margin: 0 auto;
  width: 300px;
}

button {
  background: #0084ff;
  border: none;
  border-radius: 5px;
  padding: 8px 14px;
  font-size: 15px;
  color: #fff;
}

#banner-message.alt {
