Javascript Don'；我不知道在这种情况下如何更改为小写

我试图使用discord.js

awaitMessages

方法，但它似乎不适用于大写字母，因为我可能的答案（

triviacharacterslist.js

）都是小写的。我试图转换这个（在代码中），但它似乎不起作用

triviachar.js

：

const iKF = Characters.KiritoVariants;
        const possibleAnswers = [iKF.kirito0, iKF.kirito1, iKF.kirito2, iKF.kirito3, iKF.kirito4, iKF.kirito5, iKF.kirito6, iKF.kirito7, iKF.kirito8];
        const triviaKiritoEmbed = new MessageEmbed()
            .setColor('#008fff')
            .setTitle(guessCharacterString)
            .setImage(Characters.CharacterImgs.kiritoimg)
    
        msg.channel.send(triviaKiritoEmbed)

        const filterK = m => possibleAnswers.some(answer => m.content.includes(answer));
        msg.channel.awaitMessages(filterK, { max: 1, time: 15000, errors: ['time'] })
        .then(collected => {switch(collected.first().content.toLowerCase()){
            case Characters.KiritoVariants.kirito0:
                msg.channel.send(fivePoint);
                break;
            case Characters.KiritoVariants.kirito3:
                msg.channel.send(fivePoint);
                break;
            case Characters.KiritoVariants.kirito6:
                msg.channel.send(fivePoint);
                break;
            case Characters.KiritoVariants.kirito1:
                msg.channel.send(tenPoint);
                break;
            case Characters.KiritoVariants.kirito2:
                msg.channel.send(tenPoint);
                break;
            case Characters.KiritoVariants.kirito4:
                msg.channel.send(tenPoint);
                break;

                break;
            case Characters.KiritoVariants.kirito8:
                msg.channel.send(tenPoint);
                break;
        }})
        .catch(collected => msg.channel.send('too bad u took too long ya 3am'));
    }

includes（）

方法区分大小写：

const str1='kirito剑术在线'
const str2=‘Kirito剑艺在线’
console.log（str1.includes（str2））

我认为这个想法是对的，但是执行有点错误。由于您的所有答案都是小写的，因此对答案字符串调用

.toLowerCase（）

不会有多大作用。相反，您需要对字符串内容调用

.toLowerCase（）

。请参见下面的示例：

const filterK=m=>possibleAnswers.some（答案=>m.content.toLowerCase（）.includes（答案））；

我现在已经尝试过了，但不幸的是它不起作用，谢谢你的回答。在这种情况下，不起作用意味着什么？我尝试过，但在你链接的第二个图像中发生了这种情况，我没有看到机器人响应超时消息，所以我猜

等待消息

确实收集了大写字母的消息，但是

开关

案例没有正确触发。您的代码中是否仍有

开关（collected.first（）.content.toLowerCase（））

？过滤器和开关盒都需要

toLowerCase

哦，对不起，巴德，我把

开关盒上的那一个拆了，我把它放回去了，现在它可以工作了，谢谢！哦，新手犯了个错误。谢谢你指出这一点。让我投一票；）
