switch语句

Question

client.on('chat', function(channel, userstate, message, self){ 



    switch(message){ 
    case message.includes(emotes[0]): 
     numberOfEmotes[0]++; 
     console.log("Emote0 has been used " + numberOfEmotes[0] + " time(s)"); 
     break; 
    case message.includes(emotes[1]): 
     numberOfEmotes[1]++; 
     console.log("Emote1 has been used " + numberOfEmotes[1] + " time(s)"); 
     break; 
    case message.includes(emotes[2]): 
     numberOfEmotes[2]++; 
     console.log("Emote2 has been used " + numberOfEmotes[2] + " time(s)"); 
     break; 
    case message.includes(emotes[3]): 
     numberOfEmotes[3]++; 
     console.log("Emote3 has been used " + numberOfEmotes[3] + " time(s)"); 
     break; 
    } 

/* if(message.includes(emotes[0])){ 
    numberOfEmotes[0]++; 
    console.log("Emote0 has been used " + numberOfEmotes[0] + " time(s)"); 
    }*/ 


    //console.log("** " + message + " **"); 
}); 

当函数chat.on被称为消息的变量用字符串应该通过开关语句来运行，我有不同的字符串，并且如果阵列消息包含该数组中的一个字符串，运行该案例。但没有任何反应，这一切似乎正确，这可能是错误的？

交换机无法按照您的预期工作。它将交换机中写入的值与案例块中的每个进行比较。所以在你的情况下，它会比较true/false与值的消息，它不会找到相同的值，因此不会发生任何事情。 你如果使用else语句或解析消息并排除像 消息“型/ emote1”的值 提取一切AFTE斜线，并把它在开关
