layui+SSM的数据表的增删改实例(利用弹框添加、修改)

Posted in Javascript onSeptember 27, 2019

本人前端知识相当于小白，初学SSM时，了解了layui前端框架，所以开始研究了数据表的增删改查，由于js、ajax知识不是很好，所以百度了相关ajax操作，用以借鉴。希望能帮助有需要的初学者，不喜勿喷，另外有相关不足，希望大家可以指出，谢谢！

注：以下前端代码都是利用layui的框架，后台是SSM

亲测有效，希望大家提出不足！谢谢！另外后台里面有一个时间转换的类（DateUtil.formatDate（）），前端有一个例如url: '${ctx}/news/update/'，其中的${cxt}是一个指定的路径，后台写了一个类，这些有需要的，可以看我的博客，谢谢！
