官方文档:DateTime Picker 前提,引用bootstrap 页面效果: datepicker
<div style="display: -webkit-inline-box">
  <span class="input-group date date-picker margin-bottom-10" id="StartTime">
    <input type="text" class="form-control form-filter input-sm" readonly name="StartTime"
      placeholder="从" />
    <span class="input-group-btn" style="width: 25%">
      <button class="btn btn-sm default" type="button">
        <i class="fa fa-calendar"></i>
      </button>
    </span></span><span class="input-group date date-picker" id="EndTime">
      <input type="text" class="form-control form-filter input-sm" readonly name="EndTime"
        placeholder="到">
      <span class="input-group-btn" style="width: 25%">
        <button class="btn btn-sm default" type="button">
          <i class="fa fa-calendar"></i>

$(function () {
  $('.date-picker').datepicker({
    rtl: Metronic.isRTL(),
    autoclose: true,
    clearBtn: true, //清除按钮
    todayBtn: false, //今日按钮
    format: "yyyy-mm-dd"
  });
});
<script type="text/javascript" src="/assets/global/plugins/bootstrap-datepicker/js/bootstrap-datepicker.js"></script>
官方文档:datepicker 当然前提也是bootstrap 页面效果:
