javascript或jquery中的动态字段验证

这是我的Html表单，我用它创建表单和动态字段

<div style="margin:10px 0;color:#574F44;margin-left:160px;">
    <form name="frmsignup3" method="post" action="new_user2.php" style="margin-top:0px; line-height:60px;" enctype="multipart/form-data" onsubmit="return validateForm2()" >
        <input type="hidden" name="user_name" value="<?php echo $_POST['user_name']?>" />
        <input type="hidden" name="user_email" value="<?php echo $_POST['user_email']?>" />
        <input type="hidden" name="user_pass" value="<?php echo $_POST['user_pass']?>" />

我假设您有不同类型的字段。所以，当您添加新字段时，会向每个不同的类型添加相同的类。然后，您可以在向chekc发送所有类型的邮件之前轻松设置验证程序函数，如下所示：

function your_validator() {
var passed = true;
$('.Specialities').each(function(){
 var current = $.trim($(this).val());
 if (your_false_condition) passed = false;//chekc specialiti value if its not ok
});

if (passed == false) {
alert('error');
return false;
}
return true;
}

说真的，伙计-一个div可以解释的东西并不需要你的全部源代码。请减少您发布代码的大小，以便我们能够关注相关内容。现在，你所说的“验证”是什么意思？@SudiptaChatterjee Chatterjee我想让你知道动态创建的字段不能空白提交！！！！
function your_validator() {
var passed = true;
$('.Specialities').each(function(){
 var current = $.trim($(this).val());
 if (your_false_condition) passed = false;//chekc specialiti value if its not ok
});

if (passed == false) {
alert('error');
return false;
}
return true;
}
