如何從字段陣列

-5

var obja = [{USER:"bob", SCORE:2000, TIME:32, AGE:16, COUNTRY:"US"},`{USER:"jane", SCORE:4000, TIME:35, AGE:16, COUNTRY:"DE"},`{USER:"tim", SCORE:1000, TIME:30, AGE:17, COUNTRY:"UK"},` {USER:"mary", SCORE:1500, TIME:31, AGE:19, COUNTRY:"PL"}];

獲得字段名，但我想只存儲字段USER，得分，時間，年齡，國家對陣列

呃，它已經是一個數組？ '[]'是數組。你有一個對象數組，它完全包含你所要求的。 –

即時嘗試只獲取字段名稱，我想要綁定下拉字段名稱，如<選項值='用戶'>用戶 – Rajesh

因此，他們應該是一個單獨的用戶，SCOREs，TIME，AGEs，COUNTRYs數組？ – RomanPerekhrest

你可以得到一個對象鍵這樣

var obja = [{USER:"bob", SCORE:2000, TIME:32, AGE:16, COUNTRY:"US"}, {USER:"jane", SCORE:4000, TIME:35, AGE:16, COUNTRY:"DE"},{USER:"tim", SCORE:1000, TIME:30, AGE:17, COUNTRY:"UK"}, {USER:"mary", SCORE:1500, TIME:31, AGE:19, COUNTRY:"PL"}]; 
 

 
for(var key in obja[0]){ 
 
console.log(key) 
 
}
