【问题描述】：

在我的 discord 机器人中，我有很多团队。

如果我可以将所有内容一起声明，则类似于let teams = [messageID:players[]]; ，其中玩家是用户 ID 字符串数组，团队是字典数组，messageID 是他们反应的消息的 ID。

人们通过对消息做出反应来加入所述团队。当他们做出反应时，我想遍历数组找到他们做出反应的 messageID，并将他们的 ID 添加到玩家数组中。我在声明什么以及如何索引所有这些值方面遇到问题。

目前我在我的机器人顶部声明了我的团队数组，然后在创建团队消息后，我将字典推送到我的团队数组，如下所示：

teams.push(key: embedMessage.id, value: players[message.author.id]);

但这不起作用，因为当我想检查 team[x] 键/值的值以检查球员是否已经在另一个球队等时，它不知道球员 [] 是什么？非常感谢任何帮助。

                let agentString = "";
                const name = args[1];
                const language = args[2];
                const noOfPeople = args[3];
                const agents = args[4].split(',');

                for (let x in agents)
                    console.log('checking ' + agents[x])
                    if (agents[x].toLowerCase() === 'reyna')agentString = agentString + '<@&762024455391936512> '
                    else if (agents[x].toLowerCase() === 'sage')agentString = agentString + '<@&762024358105055272> '
                    else if (agents[x].toLowerCase() === 'phoenix')agentString = agentString + '<@&762024408168267807> '
                    else if (agents[x].toLowerCase() === 'raze')agentString = agentString + '<@&762024426824400919> '
                    else if (agents[x].toLowerCase() === 'viper')agentString = agentString + '<@&762024863182618676> '
                    else if (agents[x].toLowerCase() === 'brimstone')agentString = agentString + '<@&762024508734963753> '
                    else if (agents[x].toLowerCase() === 'breach')agentString = agentString + '<@&762024388014768138> '
                    else if (agents[x].toLowerCase() === 'sova')agentString = agentString + '<@&762414403399188481> '
                    else if (agents[x].toLowerCase() === 'omen')agentString = agentString + '<@&762024815744778240> '
                    else if (agents[x].toLowerCase() === 'jett')agentString = agentString + '<@&762024732660727821> '
                    else if (agents[x].toLowerCase() === 'cypher')agentString = agentString + '<@&762024650724737047> '
                    else if (agents[x].toLowerCase() === 'killjoy')agentString = agentString + '<@&762024794992410634> '
                

                const LFGEmbed = new Discord.MessageEmbed()
                    .setColor('#b34100')
                    .setTitle('LFG Post')
                    .setAuthor(message.author.username)
                    .setThumbnail('https://cdn.discordapp.com/icons/761878850920644610/0d17b72a31ddaccaf65e9cf14b8d7eed.png?size=128')
                    .setDescription(agentString)
                    .addFields(
                         name: `Name:`,
                            value: `$name`,
                         name: `Language:`,
                            value: `$language`, inline:true,
                         name: `Players:`,
                            value: `$noOfPeople/5`, inline:true,
                    )
                    .setTimestamp()

                client.channels.cache.get(channelID).send(LFGEmbed).then(embedMessage => 
                    embedMessage.react("????");
                    let players = [];
                    teams.push(
                        messageID: embedMessage.id,
                        players: players[message.author.id]
                    );
                    console.log(teams); ```

【参考方案1】：

要检查一个玩家是否已经在一个团队中，您只需搜索 teams 数组中的现有玩家：

if (!teams.find(team => team.players.find(pid => pid === idOfPlayerThatReacted))) 
   // User does not belong to any team
   const teamToAddPlayerTo = teams.find(team => team.messageId === messageIdThatThePlayerReactedTo);
   if (teamToAddPlayerTo) 
      // Existing team
      teamToAddPlayerTo.players.push(idOfPlayerThatReacted);
    else  
      // New team
      teams.push( messageId: messageIdThatThePlayerReactedTo, players: [idOfPlayerThatReacted] );
