js获取多层json最深层级数

[Heerey525]

如题，就是有个多层json对象，获取它的最深层级数

[Heerey525]

var data={"list":[{"list":[{"list":[{"list":[{"list":[{"four":"4","one":"1","three":"3","two":"2"}],"value":"4"}],"value":"3"}],"value":"2"},{"list":[{"list":[{"list":[{"four":"4","one":"1","three":"3","two":"3"}],"value":"4"}],"value":"3"},{"list":[{"list":[{"four":"4","one":"1","three":"4","two":"3"},{"four":"4","one":"1","three":"4","two":"3"}],"value":"4"}],"value":"4"}],"value":"3"}],"value":"1"},{"list":[{"list":[{"list":[{"list":[{"four":"4","one":"2","three":"3","two":"2"}],"value":"4"}],"value":"3"}],"value":"2"}],"value":"2"},{"list":[{"list":[{"list":[{"list":[{"four":"4","one":"3","three":"3","two":"2"}],"value":"4"}],"value":"3"}],"value":"2"}],"value":"3"},{"list":[{"list":[{"list":[{"list":[{"four":"4","one":"4","three":"3","two":"2"}],"value":"4"}],"value":"3"}],"value":"2"}],"value":"4"}],"value":"root"}

这种结构，只能遍历

如果用标准的树结构，就不会这么麻烦了

您好，能给我个demo吗

[天际的海浪]

var num = 0;
function recursion(obj,k) {
	num = Math.max(num,k);
	console.log(k);
	if (obj.list)
		obj.list.forEach(function(v, i){
			recursion(v,k+1);
		});
}
recursion(data,1);
console.log("最深层级数"+num);

引用 5 楼 jslang 的回复:

var num = 0;
function recursion(obj,k) {
	num = Math.max(num,k);
	console.log(k);
	if (obj.list)
		obj.list.forEach(function(v, i){
			recursion(v,k+1);
		});
}
recursion(data,1);
console.log("最深层级数"+num);

非常感谢大神，问题已解决，献上我的膝盖
