使用方法如下

<input type="text" name="productNews.createDate"
                 id="createdate" value="${productNews.createDate}"
                 onfocus="setday(this)"  />

引入js的方法

  <script language="javascript" src="js/newcalendar.js"></script>

${productNews.createDate}这是什么东东?

{productNews.createDate}是指你传递到页面的值。这只是一种获取方式。
你也可以通过其他方式传递进来。
