老师开：始提问的时候就复制了相关代码，我点击输入内容点击“确定”
我打印出了response.data拿到data数据后不知到后面怎么写才能把数据返回给后端
老师我的后端新增代码写的是否正确，前端js哪儿有点儿问题。
好帮手慕小尤

同学你好。1、在返回时，同学只是返回了code与message中的数据，并未返回数据，所以在前端中获取不到数据。
2、并在添加时，并不需要返回数据，同学在查询时进行返回就可以了。如何在查询中返回数据，建议同学参考LeaveFormServlet类中list()方法。如下所示：
3、同学在下次反馈代码时，建议同学以复制粘贴的方式将类中全部代码反馈，便于老师测试代码。
祝学习愉快！

同学你好，1、测试同学代码点击提交是可以正确添加数据的，可能是缓存的问题，建议同学清除缓存试一下。如下所示：
浏览器：Ctrl+F5
2、也有可能是同学前端代码的问题，建议同学直接点击提交试一下。
祝学习愉快！
