我有以下对象：
var abc = {
1: "Raggruppamento a 1",2: "Raggruppamento a 2",3: "Raggruppamento a 3",4: "Raggruppamento a 4",count: '3',counter: {
count: '3',},5: {
test: "Raggruppamento a 1",tester: {
name: "Ross"
}
}
};
我想检索以下结果：
> abc [1]
> abc [2]
> abc [3]
> abc [4]
> abc.count
> abc.counter.count
> abc [5]
> abc [5] .test
> abc [5] .tester
> abc [5] .tester.name
可能在插件的帮助下使用nodejs吗？
解决方法
您可以通过递归遍历对象来执行此操作：
function getDeepKeys(obj) {
var keys = [];
for(var key in obj) {
keys.push(key);
if(typeof obj[key] === "object") {
var subkeys = getDeepKeys(obj[key]);
keys = keys.concat(subkeys.map(function(subkey) {
return key + "." + subkey;
}));
}
}
return keys;
}
在问题中的对象上运行getDeepKeys(abc)将返回以下数组：
["1","2","3","4","5","5.test","5.tester","5.tester.name","count","counter","counter.count"]
