如何向Jquery UI Datepicker日期范围再添加一天?

$(".from_date").datepicker({ minDate: 0, dateFormat: "dd/mm/y", defaultDate: "+1w", numberOfMonths: 1, onClose: function() { var minDate = $(this).datepicker('getDate'); var newMin = new Date(minDate.setDate(minDate.getDate() + 1)); $(".to_date").datepicker("option", "minDate", newMin); return $(".to_date").datepicker("show"); } }); $(".to_date").datepicker({ minDate: '+1D', dateFormat: "dd/mm/y", defaultDate: "+1w", numberOfMonths: 1 });

考虑下面的例子。

$(function() {
  $(".from_date").datepicker({
    minDate: 0,
    dateFormat: "dd/mm/y",
    defaultDate: "+1w",
    numberOfMonths: 1,
    onClose: function(dText) {
      var minDate = $.datepicker.parseDate("dd/mm/y", dText);
      if (minDate != null) {
        var newMin = new Date(minDate.setDate(minDate.getDate() + 8));
        $(".to_date").datepicker("option", "minDate", newMin);
      }
    }
  }).datepicker("setDate", "+1w");
  $(".to_date").datepicker({
    minDate: "+8d",
    dateFormat: "dd/mm/y",
    defaultDate: "+8d",
    numberOfMonths: 1
  }).datepicker("setDate", "+8d");;
});

<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<label for="from">From</label>
<input type="text" id="from" class="from_date" name="from">
<label for="to">to</label>
<input type="text" id="to" class="to_date" name="to">

在这里,我们用 setDate 方法这可以确保两个字段中都有日期,因此如果用户选择或不选择日期,他们可以无误地继续操作。
