原生javascript实现简单的datagrid数据表格
编程学习 2021-07-04 21:47www.dzhlxh.cn编程入门
这篇文章主要介绍了原生javascript实现简单的datagrid数据表格的方法，效果十分棒,需要的朋友可以参考下
简单的datagrid
1.排序 自定义排序方式
2.编辑
3.拖拽
4.分页
5.单选 多选(ctrl) 线性选(shift)
6.文字render 就是给文字着色 比如 大于0红色 小于0绿色
7.对列的显示隐藏
8.分组
只是一个示例 没有什么与后台的借口
其实可以写几个回调就行了 里面有loading条 可以在没返回结果前一直显示
代码如下:
