javascript - 访问数组中的 JSON 对象

Question

我已经完成了 Lynda 有关 JSON 的类(class)，并进行了真正的搜索来解决这个错误；但是，我想我的问题太具体了，我需要一个例子。

JSON

{

  "league": "NHL",
  "odds": "spreads",
  "status": "200 OK",

  "games": [
    {

        "rot": "051",
        "odds": {

        },
        "team": "Boston Bruins",
        "score": 1
      },
      "home": {
        "rot": "052",
        "odds": {
          "acesport": "+1.5 -208",
          "betphoenix": "+1.5 -217",
          "betus": "+1.5 -200",
          "bookmaker": "+1.5 -210",
          "bovada": "+1.5 -200",
          "dsi": "+1.5 -200",
          "easystreet": "+1.5 -210",
          "jazz": "+1.5 -205",
          "mirage": "+1.5 -220",
          "open": "+1.5 -110",
          "pinnacle": "+1.5 -214",
          "sbg": "+1.5 -210",
          "sia": "+1.5 -175",
          "sportsbet": "+1.5 -280",
          "station": "+1.5 -210",
          "westgate": "+1.5 -200"
        },
        "team": "Vegas Golden Knights",
        "score": 3
      },
      "time": "7:05 PM EST",
      "status": "Final"
    }
  ]
}

根据我从搜索和视频中收集到的信息，我认为下面的代码很接近。问题一定是这只是数组中的一个值而不是另一个对象？

for (i = 0; i <= body.games.length; i++){
    for (var key in body.games[i]) {
        console.log("Game " + (i +1));
        console.log(body.games[i][key].away.odds.acesport);
    }
}

您的帖子不包含问题。我将假设问题“如何访问数组中的对象？”和“为什么我的代码不起作用？”。

也许这个例子会让你明白。

for (var i = 0; i <= body.games.length; i++) {
    var game = body.games[i];
    console.log("Game number " + (i + 1));
    console.log(game.away.odds.acesport);
    for (var key in game) {
        // This will print the strings "away", "home", "time" and "status",
        // but not the values game[key] which are "object", "object",
        // "7:05 PM EST" and "Final".
        console.log("Game property: " + key);
    }
}
