这是我的表单和 jquery 验证代码。问题是：它验证了前两个字段，即 title 和 desc，但它没有从品种字段验证。
<div class='span10 well' style='display:block;'>
<h4>Listing Details : <span class='btn btn-info btn- small' style='display:inline;'>Public</span><a href="#" class="tt"><img src='../../img/help.png' class='helpicon' /><span class="tooltip"><span class="top"></span><span class="middle">The information entered here will only shown to all customers who view your profile!</span><span class="bottom"></span></span></a></h4><br>
<div class='test span9 well'>

这是我的jQuery验证：
$(document).ready(function(){
$("#listingForm").validate({
rules: {
title: "required",
desc: "required",
breeds: "required",
price: {
required: true,
},
},
messages: {
title: "blah blah",
desc: "blah blah",
breeds: "blah blah",
price:"blah blah"
}
});
});
