我有一個(gè) Javascript 對(duì)象，如下所示。我想遍歷對(duì)象并找出值Hostnamesconst data ={ "error1": { "7": [ { "ErrorType": "Error-1A", "Hostnames": "host123.com,hostabc.com,host33a.com..." } ], "8": [ { "ErrorType": "Error-1B", "Hostnames": "host223.com,host2c.com,host43a.com..." }, { "ErrorType": "Error-1C", "Hostnames": "host1231.com,host2abc.com,host313a.com..." } ] }, "error2": { "3": [ { "ErrorType": "Error-2A" "Hostnames": "host1231.com,host2abc.com,host313a.com..." }, { "ErrorType": "Error-2B" "Hostnames": "host1231.com,host2abc.com,host313a.com..." } ], "8": [ { "ErrorType": "Error-2C" "Hostnames": "host1231.com,host2abc.com,host313a.com..." }, { "ErrorType": "Error-2D", "Hostnames": "host1231.com,host2abc.com,host313a.com..." } ] }, "error3": { "1": [ { "ErrorType": "Error-3A", "Hostnames": "host1236.com" }, { "ErrorType": "Error-3B", "Hostnames": "hostc3231.com" } ] }}我寫了以下 NodeJS 函數(shù)：const findObjectByLabel = function(obj, label) { if(obj.label === label) { return obj; } for(var i in obj) { if(obj.hasOwnProperty(i)){ var foundLabel = findObjectByLabel(obj[i], label); if(foundLabel) { return foundLabel; } } } return null;};const hostNames = findObjectByLabel(data, 'Hostnames');console.log(hostNames);上面的函數(shù)拋出錯(cuò)誤：Error: undefined : RangeError: Maximum call stack size exceeded
如何迭代深層嵌套對(duì)象并查找特定鍵的值？
