Question

我无法从我从某个API服务器检索的数据中获取对象属性名称：

var arrData = [{"data":
{"plmn":"Voda","id":"B193","time":1499257121817,"cell":{"rsrp":
[-132.5,-108.88],"rsrq":[-18.69,-6.56],"earfcn":1550,"pci":454,"celltiming":    
[252],"sinr":-12.8,10.7]},"mac":"9C65F9"},"time":1499282331405,
},{"data":
{"plmn":"Voda","rssi":-106,"id":"4179","time":315939662698,"cells":
[{"sc":453,"ecno":-19.53,"r99":"intraMon","rscp":-125.53,"ch":10837},
{"sc":452,"ecno":-13.97,"r99":"active","rscp":-119.97,"ch":10837},
{"sc":452,"ecno":-19.53,"r99":"active","rscp":-125.53,"ch":10812},
{"sc":453,"ecno":-19.37,"r99":"intra","rscp":-125.37,"ch":10812}],"mac":
"9C65F9211012"},"time":1499282452590,"deviceID":"9C65F9211012"}]

我已尝试使用此代码：

var collectField = [];

 for (var prop in arrData) {
    if (arrData.hasOwnProperty(prop)) {
       collectField.push(prop);
    }
 }

// and still wrong Outputs: [0,1,2,3.....]

 console.log(collectField);

我预期的输出结果：

[plmn,id,time,cell,,ecno,cells,rscp..and all of that object field]

希望有人可以帮助解决这个问题。

提前致谢

<VirtualHost *:9002> ServerName test.something.com DocumentRoot "/data/site/web" <Directory "/data/site/web"> Require all granted <IfModule mod_rewrite.c> Options -MultiViews RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ app.php [QSA,L] </IfModule> </Directory> <Directory /data/site/web/vendor> <IfModule mod_rewrite.c> RewriteEngine Off </IfModule> </Directory> ErrorLog /data/site/app/logs/error.log CustomLog /data/site/app/logs/access.log combined </VirtualHost>构造不会从数组中检索对象但它的索引。因此，您尝试访问号码for-in。首先，您需要访问数组成员，然后访问属性，例如。像这样：

hasOwnProperty

Object.getOwnPropertyNames函数（JavaScript）从这个数据它不起作用
