[jQuery] Get value from <option>... Internet Explorer 7

[jQuery] Get value from <option>... Internet Explorer 7


Hi, I try to catch selected choice in my dropdown inside IE7.
<span id="prefix">
<select>
<option value="1">08:00 - 16:30&nbsp;&nbsp;(8:00h)</option>
<option value="2">09:00 - 17:30&nbsp;&nbsp;(8:00h)</option>
</select>
</span>
In my jQuery-function I use this to set the value to my string
"timecode":
$(document).ready( function() {
    $('#prefix option').click( function() {
        timecode = $(this).val();
    });
});
It´s works fine in FF but not in IE. How can I get the chosen thing
inside IE to my variable "timecode"?
Best regards
Tommy
