我有多组输入字段，其中包含姓名和电子邮件。如果用户可以通过单击添加新按钮来添加新的输入字段集。在提交表单时如何验证这些新添加的输入字段？我听说这可以通过 using 来完成jquery.each，但我不知道如何实现它。有什么帮助吗？

代码如下：

<div class="subsriber_list_view">
    <div class="sr">
Name:<input type="text" class="subsribe_name" autocomplete="off" name="name[]">
Email:<input type="text" class="subsribe_mail" autocomplete="off" name="email[]">
</div>      
<div class="subsriber_list_container" id="sr1">
    <div class="sr">
    Name:<input type="text" class="subsribe_name" autocomplete="off" name="name[]">
    Email:<input type="text" class="subsribe_mail" autocomplete="off" name="email[]">
    </div>
    <div class="s_remove">
     <a href="javascript:void(0)">Remove</a>
    </div>
    </div>
    <div class="subsriber_list_container" id="sr2">
       <div class="sr">
    Name:<input type="text" class="subsribe_name" autocomplete="off" name="name[]">
        Email:<input type="text" class="subsribe_mail" autocomplete="off" name="email[]">
       </div>
    <div class="s_remove">
            <a href="javascript:void(0)">Remove</a>
        </div>
    </div>
    <div class="subsriber_list_container" id="sr3">
            <div class="sr">
                Name:<input type="text" class="subsribe_name" autocomplete="off" name="name[]">
                Email:<input type="text" class="subsribe_mail" autocomplete="off" name="email[]">
            </div>
        <div class="s_remove">
            <a href="javascript:void(0)">Remove</a>
        </div>
    </div>
    <div class="subsriber_list_container" id="sr4">
            <div class="sr">
                Name:<input type="text" class="subsribe_name" autocomplete="off" name="name[]">
                Email:<input type="text" class="subsribe_mail" autocomplete="off" name="email[]">
            </div>
        <div class="s_remove">

你可能想要这样..，DEMO

<form method="post" action="" id="userForm">
    <input type="text" name="name" />
    <input type="text" name="email" />
    <input type="text" name="name1" />
    <input type="text" name="email1" />
    <input type="submit" value="Submit" id="submitBtn" />
</form>



$(function() {

 $("#submitBtn").click(function() {

 $("#userForm input[type=text]").each(function() {

        if(!$(this).val()) {
            alert("Please Fill All Fields");
            $(this).addClass('warn');
            $(this).focus();
            return false;
     }    
    });
    return false;
});
});

插件将使您的喜欢更容易和管理，无论如何附加一个点击处理程序到表单提交按钮

$("#form-submit-btn").on("click",function(e){
 e.preventDefault();//prevent default form submission

 //perform your validation login
 //if the form is valid
  //$(this).closest('form').submit();
 //else
  //show error messages

});
