dojo中DateTextBox日期格式yyyy-MM-dd转化为数据库中yyyyMMdd

前端之家收集整理的这篇文章主要介绍了dojo中DateTextBox日期格式yyyy-MM-dd转化为数据库中yyyyMMdd前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

1、问题描述

在dojo中,日期格式是yyyy-MM-dd,即页面显示的日期格式;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;

(2)然后,将DateTextBox显示的值进行截取

(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
