循环遍历 JavaScript 中的嵌套 object

Question

我想遍历servers javascript object 并获取serverName和serverStatus

 let servers = { server1: { serverName: "India", serverStatus: "fair" }, server2: { serverName: "USA", serverStatus: "Good" }, server3: { serverName: "Aus", serverStatus: "Excelent" }, server4: { serverName: "England", serverStatus: "Super" } } for (let server in servers) { for (let s in server) { console.log(s.serverName); } }

您不需要嵌套循环。 第一个循环遍历属性名称，您只需要访问相应的属性。

 let servers = { server1: { serverName: "India", serverStatus: "fair" }, server2: { serverName: "USA", serverStatus: "Good" }, server3: { serverName: "Aus", serverStatus: "Excelent" }, server4: { serverName: "England", serverStatus: "Super" } } for (let server in servers) { console.log(`Name: ${servers[server].serverName} Status: ${servers[server].serverStatus}`); }
