Question

我在使用discord.js时遇到问题，我在2个小时前就做对了，但是我尝试向它添加另一个图像搜索，现在我无法将其恢复到原来的状态。我尝试重组小块代码，方括号，括号和分号，甚至尝试撤消Visual Studio中的更改。


     switch(args[0]) {
             case 'iDog':
               image(msg);
               break;
           }
           //emoji commands
           switch(args[0]) {
             case 'eYOUTUBE':
               if(args[1] === 'emoji') {
                 msg.react('668632526641692680')
               } else {
                 msg.reply('You must specify either 5 things'); //I'll decide the things later or learn how to react with a uploaded emoji
               }
             break;
             case 'eTWITTER':
              if(args[1] === 'emoji') {

          var links = $(".image a.link");

          var urls = new Array(links.length).fill(0).map((v, i) => links.eq(i).attr("href"));

          console.log(urls);

          if (!urls.length) {

              return;
          }

          // Send result
          msg.channel.send( urls[Math.floor(Math.random() * urls.length)]);

     }

如果我在底部附近做function image(msg)，则在键入不和谐音时不会弹出任何内容，因为显然我必须做function iDog(msg)，但是当我这样做时，文字会变得更暗，当我将鼠标悬停时在它上面，它显示“已声明iDog，但从未读取过”，并且在终端中收到错误消息“未定义图像”

尝试从以下位置更改

function iDog(msg) {

到

function image(message) {
