所以我正在研究一个项目，在其中我多次调用一个名为letterpool的数组，其中包含字母表中的所有字母。每次调用一个字母时，它都会从列表中删除，如果用户再次尝试选择它，则会收到错误消息。但是我似乎无法得到消息。确切的代码是
}
}
}
else if (userGuess.match(letters) && userGuess.length === 1) {
for (var i = 0; i < letterpool.length; i++) {
if (userGuess !== letterpool){
document.getElementById("feedback_box").innerHTML= "You allready guess that one there skippy!"
}
}
}
}
}else {
document.getElementById("feedback_box").innerHTML= 'please enter one letter, numbers need not apply .';
}
所有代码
