注意：以下代码仅用于演示,我正在使用jQuery和jQuery验证插件.
假设我有一个包含两个字段(电子邮件和库存号)的表单：
<form action="/something" method="post" id="demoForm">
Inventory No: <input type="text" class="required" name="inventory_no" />
Email: <input type="text" class="required" name="email" />
<input type='submit' value='submit' />
</form>
绑定插件形成：
jQuery(function(){
jQuery('#demoForm').validate();
});
//handle user submit
jQuery('#demoForm').bind('submit',function (e) {
e.preventDefault();
if (jQuery(e.target).valid()) {
//form is valid submit request thru ajax
jQuery.ajax({
/*more options here*/
success: function (data) {
/*
Server process request and finds that,email is already in use
and inventory number is invalid
so it sends data in some format may pe JSon
with field names and message indicating errors
eg: Email:"Already in use"
InventoryNo: "Invalid Inventory No",Now can i invalidate these two fields on form mannualy
and display the message received from server for each field
*/
}
});
}
});
如果您知道哪个字段无效,您可以使用此功能.

var validator = $( "#myshowErrors" ).validate();
validator.showErrors({
"firstname": "I kNow that your firstname is Pete,Pete!"
});
其中firstname是您的字段的名称属性;即name =“firstname”.
