如何從我的Json對象獲取所有ID，名稱值和位置到數組中

Question

所以我有json對象calend tabledata數組，可以說我想迭代其中的所有對象並獲取id，因此輸出返回1,2,3,4,5,6,7,8,9,10，我也可以名稱，位置等。所以我想選擇一個鍵，我需要里面的所有可用值。

我嘗試循環對象，但didint為我工作。

for(int i = 0; i < array.length; i++) {
    JSONObject object = (JSONObject) array.get(i);

    String id = object.get("id");
    //and so on
}

var tabledata = [
    {id:1, name:"Oli Bob", location:"United Kingdom", gender:"male", rating:1, col:"red", dob:"14/04/1984"},
    {id:2, name:"Mary May", location:"Germany", gender:"female", rating:2, col:"blue", dob:"14/05/1982"},
    {id:3, name:"Christine Lobowski", location:"France", gender:"female", rating:0, col:"green", dob:"22/05/1982"},
    {id:4, name:"Brendon Philips", location:"USA", gender:"male", rating:1, col:"orange", dob:"01/08/1980"},
    {id:5, name:"Margret Marmajuke", location:"Canada", gender:"female", rating:5, col:"yellow", dob:"31/01/1999"},
    {id:6, name:"Frank Harbours", location:"Russia", gender:"male", rating:4, col:"red", dob:"12/05/1966"},
    {id:7, name:"Jamie Newhart", location:"India", gender:"male", rating:3, col:"green", dob:"14/05/1985"},
    {id:8, name:"Gemma Jane", location:"China", gender:"female", rating:0, col:"red", dob:"22/05/1982"},
    {id:9, name:"Emily Sykes", location:"South Korea", gender:"female", rating:1, col:"maroon", dob:"11/11/1970"},
    {id:10, name:"James Newman", location:"Japan", gender:"male", rating:5, col:"red", dob:"22/03/1998"},
];

在javascript中，就像這樣。

 var tabledata = [ {id:1, name:"Oli Bob", location:"United Kingdom", gender:"male", rating:1, col:"red", dob:"14/04/1984"}, {id:2, name:"Mary May", location:"Germany", gender:"female", rating:2, col:"blue", dob:"14/05/1982"}, {id:3, name:"Christine Lobowski", location:"France", gender:"female", rating:0, col:"green", dob:"22/05/1982"}, {id:4, name:"Brendon Philips", location:"USA", gender:"male", rating:1, col:"orange", dob:"01/08/1980"}, {id:5, name:"Margret Marmajuke", location:"Canada", gender:"female", rating:5, col:"yellow", dob:"31/01/1999"}, {id:6, name:"Frank Harbours", location:"Russia", gender:"male", rating:4, col:"red", dob:"12/05/1966"}, {id:7, name:"Jamie Newhart", location:"India", gender:"male", rating:3, col:"green", dob:"14/05/1985"}, {id:8, name:"Gemma Jane", location:"China", gender:"female", rating:0, col:"red", dob:"22/05/1982"}, {id:9, name:"Emily Sykes", location:"South Korea", gender:"female", rating:1, col:"maroon", dob:"11/11/1970"}, {id:10, name:"James Newman", location:"Japan", gender:"male", rating:5, col:"red", dob:"22/03/1998"} ]; for(let i = 0; i < tabledata.length; i++) { const object = tabledata[i]; console.log(object.id) } // or tabledata.map(object => {console.log(object.id)})
