实战Flask+BootstrapTable最实用服务端分页查询动态表头及数据(ajax方式)
看到这篇文章的朋友们是幸运的,我用了很久才实战出如下结果,且行且珍惜,祝好!
话不多说,有图有源码
1.看图,实现服务端动态表头数据,分页,查询,排序
1.数据准备
CREATE TABLE `goods` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(255) DEFAULT NULL COMMENT '商品名',
`no` varchar(255) DEFAULT NULL COMMENT '编号',
`price` double DEFAULT NULL COMMENT '价格',
`num` int(11) DEFAULT NULL COMMENT '数量',
`inputtime` datetime DEFAULT NULL COMMENT '日期',
`content` varchar(255) DEFAULT NULL COMMENT '说明',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=301 DEFAULT CHARSET=utf8;
