ztree的使用

在开发中想使用树tree的列表 后来用的是ztree

看过可以使用的有bootstrap treeview ,UI: easyUI, layui, BUI,Jquery UI等等;

ztree的学习源头:

http://www.treejs.cn/v3/main.php#_zTreeInfo

demo和api很丰富, 常用功能足够使用了

我自己的项目中 重要用到了radio和checkout 选项

最后由于数据太多 自己做了个简单的模糊搜索高亮显示 

学习源头:https://blog.csdn.net/qq_34149805/article/details/78223922?locationNum=8&fps=1

主要用到了fontCss属性，设置通过每个树节点的highlight属性来判断其是否高亮。

然后我们定义一个全局变量（这样就可以获取上次的查询结果以消除上次查询的高亮）oldNodes来存储查询到的树节点。

var oldNodes = [];
            // 渠道的模糊搜索
