<!-- 引入moment库 -->

<!-- 在HTML模板中使用md-datepicker -->
<md-datepicker ng-model="selectedDate" md-placeholder="选择日期"></md-datepicker>

<!-- 在JavaScript代码中使用moment -->
<script>
  // 获取当前日期
  var currentDate = moment();
  
  // 格式化日期为指定的字符串
  var formattedDate = currentDate.format('YYYY-MM-DD');
  
  // 进行日期的加减运算
  var newDate = currentDate.add(1, 'days');
</script>
