下記のコードは、"マウスストーカー(デジタル)"に『背景色ボタン』と『トグルボタン』をリンクさせたものですが、トグルボタンの表示が"clock
on"⇔"clock off"でははなくて、"0"⇔"1"と表示されるところまで詰まって、その先は進みません。  
どこに問題があるのか、ご教示いただけませんでしょうか？

javascript html
ボタンの切り替え表示を、数値(0と1)や真偽(trueとfalse)ではなくて、"on"⇔"off"と切り替えるには？
以下の行が誤っています。

```

    document.getElementById("tog").value = num;
    
```

↓

```

    document.getElementById("tog").value = num ?"clock on":"clock off";
    
```

以下の様に修正

```

    num = 1;
    function toggle(){
     num ^= 1; 
    document.getElementById("tog").value = num ? "clock OFF" : "clock ON";
    
```
