Form validation with SELECT field using Jquery

Form validation with SELECT field using Jquery

Jquery Isn't alerting me when their is no value selected from the Rating
form. Would it be because selected="selected" is actually being seen as a
value to jquery ?
<label for="rating">Rating</label>
<select id="rating" name="rating" />
<option selected="selected" disabled="disabled">Select a
Rating</option>
<option value="Terrible">Terrible</option>
<option value="Fair">Fair</option>
<option value="Ok">Ok</option>
<option value="Good">Good</option>
<option value="Excellent">Excellent</option>
</select>
$(document).ready(function(){
// No value for movie_title
if ($('#movie_title').val() == "" ) {
alert ("No Film");
}
// No Value for actor
if ($('#leading_name').val() == "") {
alert ("No actor");
}
// No value for rating
if ($('#rating').val() == "") {
alert ("No Rating");
}
//No value for review
if ($('#review').val() == "") {
alert ("No review");
}
// Focus on first form field.
$("input:text:visible:first").focus();
})
