アナログ時計を消しているとき(KILL(切る))、"サイズの切り替えボタン"を押すと、  
水面下で切り替えが行われていたので、下記のソースのように"continue"を使って  
みました。  
そうしましたところ、アナログ時計を出した１回目は、サイズの切り替えが繰り返し  
できますが、消してからもう一度出すと、サイズの切り替えができなくなります。  
"付け消しボタン"で _消したときだけ_ 、"サイズ切り替えボタン"を _機能しなくする_ には、  
どうすればいいでしょうか？

なお、追加した文は、  
document.getElementById('tog1').onclick="continue";  
です。

question
javascript html
"付け消しボタン"で消したときだけ、"サイズ切り替えボタン"を機能しなくする方法
機能させないために`.onclick='continue'`していますが、(`.onclick=null`の方がいいかと思います。）  
`else`で無効にした関数を設定し直す必要があると思います。  
以下は例

```

    if(num == 1){ 
        document.getElementById('Od').style.visibility="hidden";
        document.getElementById('Of').style.visibility="hidden";
        document.getElementById('Oh').style.visibility="hidden";
        document.getElementById('Om').style.visibility="hidden";
        document.getElementById('Os').style.visibility="hidden";
        document.getElementById('tog1').onclick=null;
    } else { 
        document.getElementById('Od').style.visibility="visible";
        document.getElementById('Of').style.visibility="visible";
        document.getElementById('Oh').style.visibility="visible";
        document.getElementById('Om').style.visibility="visible";
        document.getElementById('Os').style.visibility="visible";
        document.getElementById('tog1').onclick=toBigger;
    } 
    
```

後、質問とは直接関係ないですが、非表示と表示は親の要素でできますので、  
以下の様に書けます。

```

    if(num == 1){
        document.getElementById('clock').style.visibility="hidden";
        document.getElementById('tog1').onclick=null;
    } else {
        document.getElementById('clock').style.visibility="visible";
        document.getElementById('tog1').onclick=toBigger;
    } 
    
```
