如果 JSON 中的数据存在语句不起作用

【中文标题】如果 JSON 中的数据存在语句不起作用【英文标题】：if data exists statement in JSON not working 【发布时间】：2021-01-31 11:03:40 【问题描述】：我有一个 JSON sn-p，它应该检测 API 中是否存在特定类型的数据。
api端点是https://fortnite-api.com/v1/stats/br/v2?name=chefbezos
当我运行console.log（data.data.stats.all.trio）时，它给了我null。但它仍然显示带有 triostats 类的 div。代码有问题吗，因为data.data.stats.all.trio == "null" 为真，因为console.log(data.data.stats.all.trio) 为空。感谢您的帮助！
if(typeof data.data.stats.all.trio == "null")
var trioAllMP = data.data.stats.all.trio.minutesPlayed;
var trioAllMatches = data.data.stats.all.trio.matches;
var trioML = Math.round((trioAllMP/trioAllMatches + Number.EPSILON) * 100) / 100 + ' Minutes';
var trioAllWins = data.data.stats.all.trio.wins;
var trioAllWinrate = data.data.stats.all.trio.winRate;
var trioAllKills = data.data.stats.all.trio.kills;
var trioAllDeaths = data.data.stats.all.trio.deaths;

var trioAllScore = data.data.stats.all.trio.score;

var trioAllPO = data.data.stats.all.trio.playersOutlived;

【问题讨论】：
null（实际的空值）和字符串“null”不是一回事。 hmm，那我怎么告诉JS我想要真正的null呢？ 不使用字符串？检查 null（一个 null），而不是“null”（一个字符串） 不起作用，即使没有字符串 但你的逻辑似乎倒退了；你基本上说“如果这是空的，那么从它访问一些属性。但它是空的，它不会有任何。 【参考方案1】：请使用缩进...

如果比较相同并且它们彼此相邻，请考虑仅使用一个 if 语句！
