所以基本上我想要实现的是浏览full.json文件，特别是在partial.json指纹数组中的每一行上查找指纹数组，一旦有匹配，就会打印/保存一个时间戳

---

例如，这里的partialjson[0]。指纹[0]与fulljson[1]匹配。指纹[0]因此fulljson[1]。时间戳将被打印等。如果同一时间戳被多次打印，则与指纹可以在同一时间戳上匹配无关。

您必须解析部分数组，并检查完整数组中的每个对象

let timestamps = [];

// parse all partial items
partial.map( (item) => {

   // parse all fingerprints of each item
   item.fingerprint.map( (fprint) => {

      // parse all full items
      full.map( (fullitem) => {

         // check if the current fingerprint exists in the array of the current full item
         if (fullitem.fingerprint.indexOf(fprint) !== -1) {
            timestamps.push(fullitem.timestamp);
         }
      });
   });
});

console.log(timestamps);

对于数据集，时间戳数组将包含：

[4380, 4380, 4380, 4380, 4380, 4380, 4380, 4380, 4390, 4390, 4390, 4390, 4390]

希望这有帮助。

您尝试过特定的算法吗？有什么具体问题吗？非常感谢！
