javascript - 如何在jQuery中将开始日期的默认值设置为昨天和结束日期为今天

Question

我想将 start_date 和 end_date 字段的默认值分别显示为昨天和今天。

这是我的代码：

$(document).ready(function () {

  $('#start_date .input-group.date').datepicker({
      startView: 1,
      todayBtn: "linked",
      keyboardNavigation: false,
      forceParse: false,
      autoclose: true,
      format: 'yyyy-mm-dd'
      default:today
  });
  $('#end_date .input-group.date').datepicker({
      startView: 1,
      todayBtn: "linked",
      keyboardNavigation: false,
      forceParse: false,
      autoclose: true,
      format: 'yyyy-mm-dd'
  });

  $('#published_date .input-group.date').datepicker({
      startView: 1,
      todayBtn: "linked",
      keyboardNavigation: false,
      forceParse: false,
      autoclose: true,
      format: 'yyyy-mm-dd'
  });

});

我的 HTML：

<div class="col-md-2">
  <div class="form-group" id="start_date">
    <label for="">Start Date<span style="color: red;">&nbsp;</span></label>
    <div class="input-group date">
      <span class="input-group-addon"><i class="fa fa-calendar"></i></span>
      <input  type="text" class="form-control" required name="start_date">
    </div>
  </div>
</div>
<div class="col-md-2">
  <div class="form-group" id="end_date">
    <label for="">End Date<span style="color: red;">&nbsp;</span></label>
    <div class="input-group date">
      <span class="input-group-addon"><i class="fa fa-calendar"></i></span>
      <input  type="text" class="form-control" required name="end_date">
    </div>
  </div>
</div>

这是您也可以通过减去天数和月份或年份来分配的代码示例。请检查。

 var d = new Date();     
 var currMonth = d.getMonth();
 var currYear = d.getFullYear();    
 var currDate = d.getDate();

 var startDate = new Date(currYear, currMonth, d.getDate());

 var endDate = new Date(currYear, currMonth, currDate - 1);

 $('#start_date').datepicker('setDate', startDate);
 $('#end_date').datepicker('setDate', endDate);
