Javascript 如何使用节点js将字符串路径转换为JSON父子树？
我一直在尝试使用Javascript 如何使用节点js将字符串路径转换为JSON父子树？,javascript,node.js,json,ecmascript-6,treeview,Javascript,Node.js,Json,Ecmascript 6,Treeview,我一直在尝试使用节点js将路径数组转换为JSON父子树。我正在跟随@Nenad Vracar建造这棵树的答案。我使用的是我稍微修改过的上述答案。下面是我的代码： function buildTree(obj) { let result = []; let level = { result }; obj.forEach(item => { if (typeof item.fsLocation != "undefined") {
节点jsJSONfunction buildTree(obj) {
let result = [];
let level = {
result
};
obj.forEach(item => {
if (typeof item.fsLocation != "undefined") {
var obj = {}
var path = ""
item.fsLocation.split('/').reduce((r, name, i, a) => {
path += "/"+name
if (!r[name]) {
r[name] = {
result:[]
};
obj = {
name,
children: r[name].result
}
if(r[name].result.length < 1){
obj["path"] = item.fsLocation
obj["fileSize"] = item.fileSize
obj["createDate"] = item.createDate
obj["editDate"] = item.editDate
obj["fileType"] = item.fileType
obj["version"] = item.version
}
r.result.push(obj)
}
return r[name];
}, level)
}
})
return result
}

你知道如何生成上述输出吗？总是倾向于可读性而不是花哨：
