大家好
我有一个对象数组,需要打印出每个节点值的路径,并打印出特定节点(按名称)的最后一个键和值。
这是对象数组或JSON格式:
[{
"Name": "2007",
"Elements": [{
"Name": "country1",
"Elements": [{
"House": "house1",
"water": 1.8
}],
"Data": {}
},
{
"Name": "country2",
"Elements": [{
"Name": "city2",
"Elements": [{
"Name": "neighbourhood2",
"Elements": [{
"House": "house2",
"water": 2.8
}]
}],
"Data": {}
}],
"Data": {}
},
{
"Name": "country3",
"Elements": [{
"House": "house2",
"uni bill": 3.8
}],
"Data": {}
}
],
"Data": {}
}]
输出应该像这样。
2007 > country1 > house > water: 1.8
2007 > city2 > neighbourhood2 > house2 > electricity: 2.8
2007 > country3 > house > uni bill: 3.8

function objectToPaths(data) {
var validId = /^[a-z_$][a-z0-9_$]*$/i;
var result = [];
doIt(data, "");
return result;
function doIt(data, s) {
if (data && typeof data === "object") {
if (Array.isArray(data)) {
for (var i = 0; i < data.length; i++) {
doIt(data[i], s + "");
}
} else {
for (var p in data) {
if (validId.test(p)) {
doIt(data[p], s + " > " + data[p]);
} else {
doIt(data[p], s + "");
}
}
}
} else {
result.push(s);
}
}
}
这是一个我在这里找到的函数的重写,但结果并不如预期。

请帮忙。
提前感谢。
