<div class="weui-cells weui-cells_form m-form">
      <div class="form-item">
        <div class="weui-cell">
          <div class="weui-cell__hd">
            <label class="weui-label"><span class="u-star">*</span>返靖时间</label>
          </div>
          <div class="weui-cell__bd">
            <input class="weui-input" type="text" placeholder="请选择" data-toggle="date" id="return_date"
              dateFormat="yyyy-mm-dd" />
          </div>
        </div>
      </div>
</div>

 // calendar
    var return_date = '2020-02-18';
    $("#return_date").val(return_date);//输入框显示默认值
    $("#return_date").calendar({
      value: [return_date],//这行代码可加可不加
      onChange: function (p, values, displayValues) {
        // return_date = values[0].split("/").join("-");
      }
    });
