如何解决Console.log不能阵列
按下乐器声音按钮将播放声音。我试图匹配console.log上的每个数组元素，但是不起作用。
为什么“ console.log”与数组匹配，有时不匹配？我的意思是，console.log有时会显示与所听到声音对应的乐器名称，有时会显示错误的名称。第一个“ console.log”是与播放的声音匹配的唯一一个。
let index;
let sounds = ["DB.WAV","CLA.WAV","TBN.WAV","REC.WAV","TRI.WAV"];
oldSounds = [];
let playSounds = function () {
index = Math.floor(Math.random() * sounds.length);
thisSound = sounds[index];
oldSounds.push(thisSound);
sounds.splice(index,1);
if (sounds.length < 1) {
sounds = oldSounds.splice(0,oldSounds.length);
}
$("#element").html("<audio autoplay><source src=\"" + thisSound + "\" type=\"audio/mpeg\"><embed src=\"" + thisSound + "\" hidden=\"true\" autostart=\"true\" /></audio>");
if(index === 0) {
console.log(`Double Bass`);
} else if(index === 1) {
console.log(`Clarinet`);
}else if(index === 2) {
console.log(`Trombone`);
}else if(index === 3) {
console.log(`Recorder`);
}else if(index === 4) {
console.log(`Triangle`);}
}

我想我终于明白了！

}
thisSound = sounds[index];
oldSounds.push(thisSound);
sounds.splice(index,1);
//checking if the code of avobe is working
console.log(oldSounds);
console.log(sounds);
if (sounds.length < 1) {
sounds = oldSounds.splice(0,oldSounds.length);
}

如果这不是您期望的，请告诉我。
$("#element").html("<audio autoplay><source src=\"" + thisSound + "\" type=\"audio/mpeg\"><embed src=\"" + thisSound + "\" hidden=\"true\" autostart=\"true\" /></audio>"); 行我想删除它，因为它给了我一个错误。只需将其粘贴回去就可以了（我希望xd）
（顺便说一句，该代码仅在按下乐器声音按钮时运行（我已经这样理解（否则，请告诉我，我会尝试修复它）））
