如何仅对一个错误字段

Question

我正在使用jQuery验证来验证表单。我的表格被分割成几个部分。表单的顶部，具有正常输入，验证错误消息正在按照我想要的方式放置。

我的问题是不会显示放在不同部分的特定错误标签。我被告知尝试使用errorplacement函数，但我不知道如何使用这个函数和一个特定的错误消息。

errorPlacement: function(error, element) {

}

在下面的代码中，您会看到两条HTML条评论。第一个是说明如果我在那里移动输入，那么将显示错误消息。第二个注释是当前输入和我实际需要的位置，但它不会显示在那里。

输入的ID为#interestHidden。

有没有人知道如何使用errorplacement来解决这条错误消息？

请参阅下面的代码

<section class="sec90">
            <h3 class="subTC">Enter your information below.</h3>
            <form action="" id="salesforce_submit" method="POST" enctype="multipart/form-data">
                <div><input id="first_name" placeholder="First Name*" class="input block" maxlength="40" name="first_name" type="text"></div>
                <div><input id="last_name" placeholder="Last Name*" class="input block" maxlength="80" name="last_name" type="text"></div>
                <div><input id="company" placeholder="Company*" class="input block" maxlength="40" name="company" type="text"></div>
                <!-- Moving it here will allow the message to display -->
        </section>
        <section class="sec90">
                <h3 class="subTC">What are you interested in?*</h3>
<!-- Moving it here, it doesn't show -->
                <div><input type="hidden" id="interestHidden" name="interestHidden" value=""></div>
                <div id="interestWrap">
                    <div class="interest">

尝试：

errorPlacement: function(error, element) {
            if(element.attr("id") == "interestHidden") {
                error.html('#interestError');
            } else {
                //Placement for other interest Hidden
            }
        },

更新了JS：

$('#salesforce_submit').validate({
        ignore: [],
        //ignore: "",
        rules: {
            first_name: {
                required: true,
                minlength: 2
            },
            last_name: {
                required: true,
                minlength: 2
            },
            email: {
                required: true,
                email: true
            },
            phone: {
                required: true,
                //digits: true,
                minlength: 10,
                alphanumeric: true
            },
            zip: {
                required: true,
                digits: true,
                minlength: 5
            },

                required: true,
                minlength: 2
            },
            interestHidden: {
                required: true,
                min: 1
            }
        },
