jquery: option plus class and click
<p>why does this only work in Firefox?  How can I make it work in all browsers?</p>

<pre><code>&lt;script type="text/javascript"&gt;
$(document).ready(function(){   
    $(".radio_c").click(function(){
        alert('message');
    });
}); 
&lt;/script&gt;

&lt;select name = "list1"&gt;
    &lt;option value="dog"&gt;dog&lt;/option&gt;
    &lt;option value="cat"&gt;cat&lt;/option&gt;
    &lt;option class="radio_c" value="car_bmw"&gt;bmw&lt;/option&gt;
    &lt;option class="radio_c" value="car_audi"&gt;audi&lt;/option&gt;
&lt;/select&gt;
</code></pre>
