1、问题描述
在dojo中，日期格式是yyyy-MM-dd，即页面上显示的日期格式；现在，数据库中的日期格式是yyyyMMdd，需要转化一下
2、问题思路
（1）首先，取DateTextBox中的值；
（3）最后，进行字符串组合，组合需要的日期格式。
3、解决步骤
（1）取值
var startDateStr = dijit.byId("startDate").get('displayedValue');
（2）截取
startDateStr.substring(0,4) startDateStr.substring(5,7) startDateStr.substring(8,10)（3）拼接
var startDate = startDateStr.substring(0,4)+startDateStr.substring(5,7)+startDateStr.substring(8,10);
4、运行结果
（1）初始化
（2）点击查询
5、页面源码
