react hooks d3实现企查查股权穿透图结构图效果详解
您的楼主邱大帅 人气:0前言
umi+antd-admin 框架中使用hooks结合d3完成类似股权穿透图和股权结构图(web)
最终效果:
股权穿透图
股权结构图
版本信息:
"d3": "4.13.0",
"antd": "3.24.2",
"umi": "^2.7.7",
股权穿透图基础功能:
1、默认上下游信息展示,如果没有上下游信息只展示自己
2、点击请求子节点信息展示,收起子节点
3、全屏功能
4、放大器放大缩小(react项目中不知道为啥使用d3.zoom方法不好使,可能跟网页中滚动事件冲突有关,最后选择单独放置放大器进行放大缩小功能)
5、移动功能
股权结构图基础功能:
1、tab切换展示上游或下游信息
2、默认展示一层
3、点击请求子节点信息展示,收起子节点
