最近、追従する文字列をクリックするたびに"切り離し⇔追従"とする面白いコードをいただき、  
これをヒントに別コードで"ボタン"をクリックするたびに"切り離し⇔追従"とするコードを作りました。  
これを、"ボタン"ではなくて、いただいたコードのようにただ"クリック"するだけで"切り離し⇔追従"とするコードに作り変えられないでしょうか。可能でしたら、教えていただけないでしょうか。  
関連箇所は、スクリプトの"function onoff(){}"あたりです。

question
javascript
追従する文字列を、"ボタン"ではなくてただクリックするだけで"切り離し⇔追従"とする方法
"ボタン”をクリックするのでなく、"ウィンドウ"上をクリックすると考えて、  
function onoff(){}内を以下のように書けば、希望通りになりました。  
まず、 _input_ タグを消し、以下のように書き換えるだけでいいです。

```

    var vis=true;//スイッチ
    function onoff(){
    vis=!vis;
    if (vis){Delay();}
    }
    window.onclick=onoff;
    
    Delay();
    
```

また、時計を"フリーズ"させないで、動いたまま切り離したいときは、以下のように書くといいです。

```

    function Delay() 
    {中略 
            ClockAndAssign();
        setTimeout(Delay, 20);
    }
    
    var vis=true;//スイッチ
    function onoff(){
    vis=!vis;
    document.onmousemove=vis? Mouse:null;
    }
    window.onclick=onoff;
    Delay();
    
```
