テキストを数値に変換する次のコードがあります。

var vals= ["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z","0","1","2","3","4","5","6","7","8","9"," ",",",".","!","?","/","\\","#","@","=","-","_",":"];
var input = prompt("Input:");
var inn = input.toLowerCase + "";
var ins = inn.split("");
var pswrd = prompt("Password(LowerCase):")
var pin = pswrd.toLowerCase + "";
var pins = pin.split("");
var out = "";
var i;
var mul = Math.floor((Math.random() * 30) + 1);
for(i=0;i<ins.length;i++){
  var num = ins[i]
  var val = vals.indexOf(num)
  var out = out+val*mul+" "
}
var out = out+"ↀ"
for(i=0;i<pins.length;i++){
  var num = pins[i]
  var val = vals.indexOf(num)
  var out = out+val*mul+" "
}
alert('Result:' + out);

しかし、理由により、実行すると次のようになりました。

何が起こっているのかわかりませんか？誰か助けてくれませんか...

前もって感謝します！

toLowerCaseオブジェクトのプロパティのようにアクセスしようとするのではなく、メソッドを呼び出す必要があります。空の文字列が連結されていることに基づいて、これらの行からすでにエラーが発生していると思われます-これにより、エラーは消えましたが、コードは「修正」されませんでした。

余談ですが、データ変更の各ステップで新しい変数を作成する代わりに、複数のメソッドを呼び出すことができます。またindexOf、現在のインデックスが既にi?

とにかく、コードブロック全体をリファクタリングするつもりはありません...しかし、これを試してください：

var vals= ["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z","0","1","2","3","4","5","6","7","8","9"," ",",",".","!","?","/","\\","#","@","=","-","_",":"];

var input = prompt("Input:");
var pswrd = prompt("Password(LowerCase):")

var inn = input.toLowerCase().split("");
var pin = pswrd.toLowerCase().split("");

var out = "";
var i;

var mul = Math.floor((Math.random() * 30) + 1);

for(i=0;i<inn.length;i++){
  var num = inn[i]
  var val = vals.indexOf(num)
  var out = out+val*mul+" "
}

var out = out+"ↀ"

for(i=0;i<pin.length;i++){
  var num = pin[i]
  var val = vals.indexOf(num)
  var out = out+val*mul+" "
}

alert('Result:' + out);
