我的作業(yè)代碼應(yīng)該提示用戶輸入密碼長度和字符類型。出現(xiàn)提示時，我希望用戶最多可以輸入 3 個答案（即“大寫、小寫、特殊”），但是當(dāng)我運行它時，它只接受一個答案。這是我的代碼，請幫助：var length = Number(prompt("Enter a password length between 8 and 128")),  charType = prompt("Enter up to 3 character types: special, numeric, uppercase, lowercase."),  password = generatePassword();document.getElementById("display").value = password;document.getElementById('copy-btn').addEventListener('click', copyPassword);function generatePassword() {  var charSets = {    lowercase: 'abcdefghijklmnopqrstuvwxyz',    uppercase: 'ABCDEFGHIJKLMNOPQRSTUVWXYZ',    numeric: '0123456789',    special: ' !"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~'  };  var charSet = charSets[charType.toLowerCase()] || charSets.lowercase;  var retVal = "";  for (var i = 0; i < length; i++) {    retVal += charSet.charAt(Math.floor(Math.random() * charSet.length));  }  return retVal;}function copyPassword() {  document.getElementById("display").select();  document.execCommand("Copy");  alert("Password copied to clipboard!");}
