从 DatePicker 加载到输入框时显示的日期

Question

我正在尝试在加载时在输入框中显示之前的月份和年份。

现在，在聚焦/单击日期选择器后，日期将被设置并显示一次。

任何人都可以帮助我在加载时显示前一个月和前一年（2016 年 2 月），这意味着在我点击 select 来自 datepicker

的任何日期之前

下面是我的代码和Demo Link JSFiddler

$(document).ready(function(){
  $('.monthYearPicker').datepicker({
    changeMonth: true,
    changeYear: true,
    showButtonPanel: true,
    dateFormat: 'MM yy',
    yearRange: "-2:+0",
    defaultDate: '-1m'
  }).focus(function() {
    var thisCalendar = $(this);
    $('.ui-datepicker-calendar').detach();
    $('.ui-datepicker-close').click(function() {
      var Month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
      var iYear = $("#ui-datepicker-div .ui-datepicker-year :selected").val(); 
      thisCalendar.datepicker('setDate', new Date(iYear, Month, 1));
      var iMonth = $("#ui-datepicker-div .ui-datepicker-month :selected").text();
    });
  });
});

.ui-datepicker-calendar {
  display: none;
}

Could anyone pls help me in displaying previous month and year (February 2016) just on load,

你只需要像这样使用setDate：

$(document).ready(function() {
  $('.monthYearPicker').datepicker({
    changeMonth: true,
    changeYear: true,
    showButtonPanel: true,
    dateFormat: 'MM yy',
    yearRange: "-2:+0",
    defaultDate: '-1m'
  }).focus(function() {
    var thisCalendar = $(this);
    $('.ui-datepicker-calendar').detach();
    $('.ui-datepicker-close').click(function() {
      var Month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
      var iYear = $("#ui-datepicker-div .ui-datepicker-year :selected").val();
      thisCalendar.datepicker('setDate', new Date(iYear, Month, 1));
      var iMonth = $("#ui-datepicker-div .ui-datepicker-month :selected").text();
    });
  }).datepicker('setDate', "-1m y"); //<<-----set this here.
});

.ui-datepicker-calendar {
  display: none;
}

<link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/base/jquery-ui.css" rel="stylesheet" />
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.min.js"></script>
<label for="startDate">Date :</label>
<input name="myDate" class="monthYearPicker" />
