需求:实现流程图功能,根据状态不同显示不同的颜色,点击有对应的点击颜色
思想:根据jsmind构建思维导图,改变节点背景颜色,获取点击节点事件当点击节点是设置节点选中背景图片。
注意:由于jsmind更新各版本api都有很大改动,所以我使用的都是官方文档注明的基于各版本都支持的api
效果:
这里的要素是根据接口返回的,具体接口数据如下:
root是根节点,chrldren是子要素,可以根据自己的需求自行改造
代码:
先引入jsmind库(我引入的最新版本0.5)
npm install jsmind@latest --save
找到刚才引入vue中的jsmind的npm包,可以看到jsmind.css,在这里可以修改我们想要的样式,但是如果在这里修改是不会更新到git版本里面去,所以我们需要在src->style文件夹内新scss文件,这样我们改动样式可以更新到git版本控制中。
新建一个scss文件内容如下:(自己新建了一个主题名字为034,可以自行更改)
