js树形数据（数组）获取最深层级数

线上演示地址：https://wenyuming.github.io/maxFloor/ 

      接口返回的树形数据中不包含层级的时候，你需要获取最深层级数就需要自己写个函数获取，这篇博客就是为那些需获取最深层级数的人准备的。各路好汉来了就留个评论呗！

函数：

            getMaxFloor (treeData) {
                let floor = 0
                let v = this
                let max = 0
                function each (data, floor) {
                    data.forEach(e => {
                        e.floor = floor
                        if (floor > max) {
                            max = floor
                        }
                        if (e.children.length > 0) {
                            each(e.children, floor + 1)
                        }
                    })
                }
                each(treeData,1)
                return max
            }

示例数据：

 

[
	{
	  	"label": "广东省",
		"children": [
			{
				"label": "梅州市",
				"children": [
					{
						"label": "兴宁市",
						"children": [
							{
								"label": "黄槐镇",
								"children": [
									{
										"label": "西埔村",

			}
		]
	},
	{"label": "一级2", "children": []},
	{"label": "一级3", "children": []}
