jQuery：在同一页面上提交两个相同表单的功能

Question

我有一个页面，它在不同部分包含两次相同的表单——一个简单的单一输入字段，用于输入电子邮件地址。我配置了以下submit 函数，我想知道允许两种形式彼此独立运行的最简单方法；因为正如我现在配置的那样，这两种形式都被脚本有效地视为一个实体。有没有办法指定在.form div 中提交 nearest 或 active 表单？或者我应该以完全不同的方式配置提交功能？感谢您在这里提供任何见解。

$(document).ready(function() {
var infoForm = $('.form form');
var formSuccessMsg = $('p.success');
var formErrorMsg = $('p.error');

infoForm.submit(function() {
    // var url = $(this).attr('action');
    var url = $(this).attr('action') + '?showtemplate=false';
    var emailInput = $('.form input[type=text]').val();
    var data = $(this).serialize();

    if( emailInput.length === 0 || emailInput == '' || !isValidEmailAddress(emailInput) ) {
        formErrorMsg.show();
        return false;
    } else {
        $.post(url, data, function(data, textStatus, jqXHR) {
            // alert('post came back');
            infoForm.hide();
            formErrorMsg.hide();
            formSuccessMsg.show();
            console.log(emailInput);
        });
        return false;
    }
});
});

更新：这是标记（表单代码由 CMS 生成）：

<div class="form">
   <div class="form-response">
      <p class="success">Thank you!</p>
      <p class="error">Please enter a valid email address</p>
   </div>
   <form id="mc2e7cmoduleform_1" method="post" action="post" enctype="multipart/form-data">
      <div class="info-packet-form">
         <div class="required"><input type="text" name="mc2e7cfbrp__35" value="" size="25" maxlength="80"   id="fbrp__35" /></div>
         <div class="submit"><input name="mc2e7cfbrp_submit" id="mc2e7cfbrp_submit" value="Submit" type="submit" class="fbsubmit"   /></div>
      </div>
   </form>
</div>

$(document).ready(function() {
    var infoForm = $('.form form');

    infoForm.submit(function() {
        // create a var to reference this specific form
        var $thisForm = $(this);

        // assuming you want to only show the messages nearest to your form, 
        // you can select the parent div and find the response divs in there too.
        // create a reference to the specific parent div (div class="form") 
        var $parent = $thisForm.parent();

        // these will reference the specific fields specific to this form
        var formSuccessMsg = $parent.find('p.success');
        var formErrorMsg = $parent.find('p.error');

        var url = $thisForm.attr('action') + '?showtemplate=false';
        var emailInput = $thisForm.find('input[type=text]').val();

        if( emailInput.length === 0 || emailInput == '' || !isValidEmailAddress(emailInput) ) {
            formErrorMsg.show();
            return false;
        } else {
            $.post(url, $thisForm.serialize(), function(data, textStatus, jqXHR) {
                // alert('post came back');
                $thisForm.hide();
                formErrorMsg.hide();
                formSuccessMsg.show();
                console.log(emailInput);
            });
            return false;
        }
    });
});
