Unusual actions exhibited by the element in array[value]

I am facing an issue where I cannot seem to match a member (from the members array) with an officer (from the officers array), even when using the exact known value. There seems to be something missing in my implementation.

https://i.sstatic.net/VLM8o.png

    getClanMemberInfo() {
  this.clanMemberInfo = [];
  console.log(this.clan.members);
  console.log(this.clan.officers);
  for (var i = 0; i < this.clan.members.length; i++) {
    firebase
      .firestore()
      .collection("profiles")
      .doc(this.clan.members[i])
      .get()
      .then(profile => {
        var info = profile.data();
        console.log(this.clan.officers['sJUZKKhLDvPDBWPILdzCN9waFpb2'])
        if (this.clan.officers[this.clan.members[i]]) {
          console.log("Hi officer");
          info.officer = true;
        } else {
          console.log("BAT");
          info.officer = false;
        }
        this.clanMemberInfo.push(info);
      });
  }
}

Even though I have provided the exact value to check, it still shows as undefined in the console logs. However, the earlier console logs show that they are not empty.

I am puzzled as to why a straightforward comparison is failing.

for (var i = 0; i < this.clan.members.length; i++) {
    firebase
      .firestore()
      .collection("profiles")
      .doc(this.clan.members[i])
      .get()
      .then(profile => {
        var info = profile.data();

        for (var o = 0; o < this.clan.officers.length; o++) {
          console.log(this.clan.officers[o]);
          console.log(this.clan.members[0]);
          if (this.clan.officers[o].toString() === this.clan.members[i]) {
            console.log("Hi officer");
            info.officer = true;
          } else {
            console.log("BAT");
            info.officer = false;
          }
        }

        this.clanMemberInfo.push(info);
      });
  }
}

Answer №1

it appears that this.clan.officers is stored as an array of strings, rather than a dictionary.

thus, the value of this.clan.officers[0] is set to 'sJUZKKhLDvPDBWPILdzCN9waFpb2'

however, trying to access this.clan.officers['sJUZKKhLDvPDBWPILdzCN9waFpb2'] results in nonsensical output.

Answer №2

To verify the presence of a specific string within an array of values, you can utilize Array.prototype.includes().

containsString = exampleArray.includes('specificValue');

Answer №3

To start with, the values in an Array can be retrieved using their corresponding index.

retrieveClanMembers() {
  this.clanMemberInfo = [];
  console.log(this.clan.members);
  console.log(this.clan.officers);
  for (var i = 0; i < this.clan.members.length; i++) {
    firebase
      .firestore()
      .collection("profiles")
      .doc(this.clan.members[i])
      .get()
      .then(profile => {
        var info = profile.data();
        // Utilize 'members' array with index when looping through its length
        console.log(this.clan.members[i])
        // Determine if a member is also an officer
        if (this.clan.officers.includes(this.clan.members[i])) {
          console.log("Hi officer");
          info.officer = true;
        } else {
          console.log("BAT");
          info.officer = false;
        }
        this.clanMemberInfo.push(info);
      });
  }
}
