jQuery在输入中验证相同的名称

Question

此表单具有相同名称但相似（增量）ID 的输入。

表格应该验证是否有姓名，年龄必须是强制性的..

现在只有第一个输入是强制性的。

这是我的代码：

    <form id="people">
        <div class="section">
            <input id="person1" name="person" class="person" type="text" placeholder="First Name" />
            <input id="age1" name="age" class="age" type="text" placeholder="Age" />
        </div>
        <div class="section">
            <input id="person2" name="person" class="person" type="text" placeholder="First Name" />
            <input id="age2" name="age" class="age" type="text" placeholder="Age" />
        </div>
        <div class="section">
            <input id="person3" name="person" class="person" type="text" placeholder="First Name" />
            <input id="age3" name="age" class="age" type="text" placeholder="Age" />
        </div>
        ...
        <input type="submit" id="submit" name="submit" value="Add" />
    </form>
    <script type="text/javascript">
        $(function(){
            $('#people').validate();
            $('#submit').click(function(){
                $('[id^="person"]').each(function(){
                    if ($(this).val().length>0){
                        //alert($(this).val());
                        //alert($(this).parent().find('.age').val());
                        $(this).rules('add', {
                            required: true,
                            minlength: 2,
                            messages: {
                                required: "Specify the person name",
                                minlength: "Minimum of 2 characters"
                            }
                        });
                        $(this).parent().find('.age').rules('add', {
                            required: true,
                            number: true,
                            messages: {
                                required: "Must have an age",
                                number: "Specify a valid age"
                            }
                        });
                    }
                });
            });
        });
    </script>
</body>

我没有 100% 的方法，但我认为有几个问题。一个是使用提交点击作为触发器可能会干扰单独调用来验证表单（即验证两次），第二个是输入没有唯一的名称。

更新：

   <form id="people" method="post">
        <div class="section">
            <input id="person1" name="person1" class="person" type="text" placeholder="First Name" />
            <input id="age1" name="age1" class="age" type="text" placeholder="Age" />
        </div>
        <div class="section">
            <input id="person2" name="person2" class="person" type="text" placeholder="First Name" />
            <input id="age2" name="age2" class="age" type="text" placeholder="Age" />
        </div>
        <div class="section">
            <input id="person3" name="person3" class="person" type="text" placeholder="First Name" />
            <input id="age3" name="age3" class="age" type="text" placeholder="Age" />
        </div>
        <input type="submit" id="submit" name="submit" value="Add" />
    </form>


$(function() {
    $('#people').validate();

    $('.person').blur(function() {

        if ($(this).val().length) {

            //alert($(this).val());
            //alert($(this).parent().find('.age').val());
            $(this).rules('add', {
                required: true,
                minlength: 2,
                messages: {
                    required: "Specify the person name",
                    minlength: "Minimum of 2 characters"
                }
            });

            $(this).next('input').rules('add', {
                required: true,
                number: true,
                messages: {
                    required: "Must have an age",
                    number: "Specify a valid age"
                }
            });

        }
    });
});
