Question

有人可以告诉我为什么这不起作用，它在另一代码中起作用，但是在此代码中不起作用...

代码：

channel.send(`@everyone ${member}`, BoosterEmbed)

错误：

channel.send(`${member}`, BoosterEmbed)
                ^
ReferenceError: member is not defined

Answer 1

完整代码：

bot.on('guildMemberUpdate', (oldMember, newMember, member) => {
    const channel = newMember.guild.channels.cache.get('705164407008919584');
    const BoosterEmbed = new Discord.MessageEmbed()
        .setColor('#D605DC')
        .setTitle(`${member} just boosted the server wtf`)
        .setDescription('Thanks for boost you rich bastard')
        .setImage('https://media.tenor.com/images/8db3a7eea372ae195657b4e8ddcbf6d9/tenor.gif')
        .setTimestamp()



    if (oldMember.roles.cache.size !== newMember.roles.cache.size) {
        if (!oldMember.roles.cache.has('713131722409115820') && newMember.roles.cache.has('713131722409115820')) {
            channel.send(`@everyone`, BoosterEmbed)

        }
    }
});

没有错误，但不标记成员

图片 Embed 它发送

请注意，根据 guildMemberUpdate 的文档如下，仅包含两个参数：

/**
* Emitted whenever a guild member changes - i.e. new role, removed role, nickname.
* Also emitted when the user's details (e.g. username) change.
* @event Client#guildMemberUpdate
* @param {GuildMember} oldMember The member before the update
* @param {GuildMember} newMember The member after the update
*/

您可以在这里找到：https://github.com/discordjs/discord.js/blob/stable/src/client/actions/GuildMemberUpdate.js#L23

请在您的代码中使用 newMember 代替 member。这应该可以解决您面临的问题。

bot.on('guildMemberUpdate', async (oldMember, newMember) => {
      const hadRole = oldMember.roles.cache.find(role => role.name === '<ROLE NAME>');
      const hasRole = newMember.roles.cache.find(role => role.name === '<ROLE NAME>');
    
      if (!hadRole && hasRole) {
           let level = newMember.guild.premiumTier === 0 ? "No Level" : `${newMember.guild.premiumTier}`;
     
        let boost = newMember.guild.premiumSubscriptionCount;
        
        
        
        let embed = new Discord.MessageEmbed()
        .setThumbnail(newMember.user.displayAvatarURL({ dynamic: true }))
        .setTitle(`${newMember.user.username} just boosted the server!`)
    
    .setDescription(`Thank you **<@${newMember.user.id}>** for boosting the server.
    Because of you, we are now have **${boost}** boost in total.`)
    
     .setColor("#8f1b85")
    .setFooter(`${newMember.guild.name} Level : ${level}`)
       
          
        newMember.guild.channels.cache.get("<ChannelID>").send(embed);
      
      
      
      
      }
    
    
    
    
    
    }
    )
