下記のソースコードは、マウスストーカーのアナログ時計の外周(DATE)の移動速度を、  
セレクトタグで作ったものですが、検索したところ、optionに"onclick"を入れても  
IEでは動作しない，と書かれていました(＊一応、動作していますが…？)。  
全てのブラウザで見られるようにするには、どのように書き換えたらよろしいのでしょうか。

question
javascript html
すべてのブラウザで見られるようにするには？
`select` の `onchange` を使うのが定番かなと思います。

```

    <select id="step" onchange="changeSTEP(this.value)">
      <option value="0.05">FAST</option>
      <option value="0.02">SLOW</option>
      <option value="0" selected>ORIGINAL</option>
      <option value="-0.02">REVERSE</option>
    </select>
    
```

としておいて、  
呼び出されたスクリプトでは次の様にします。

```

    function changeSTEP(value){
        step = value * 1;//数値に変換
    }
    
```

※セレクトしたアイテムが変化しない場合にはイベントは起こりません。`var step=0;`としているので問題はないはず。
