javascript -display dif button when dif selected
<p>I'm newbie in programming javascript. Can someone show me how to make like this?</p>

<pre><code>&lt;select name="select" id="select"&gt;
  &lt;option value="a"&gt;a&lt;/option&gt;
  &lt;option value="b"&gt;b&lt;/option&gt;
&lt;/select&gt;
</code></pre>

<p>When I select "a" the "A" button will appear, then when I select "b" the "B" button will appear.</p>

<pre><code>&lt;input type="submit" name="button" id="button" value="A"&gt;
</code></pre>
