按enter键时提交Magento AJAX新闻稿

我使用代码通过一个提交按钮通过AJAX提交时事通讯信息，但不幸的是，当用户填写他们的电子邮件地址并按enter键时，只需重新加载页面，而不保存任何数据

我想让一个用户按enter键，以获得与用户单击submit按钮相同的结果。谢谢你的智慧/指导

这是我目前的代码：

<div class="block block-subscribe">
    <div id="feedback" style="display:none" class="mini-newsletter">
    Thank you for subscribing to our newsletter! 
    </div>

    <form name="newsletter-form" id="newsletter-form" method="post"> 
        <div class="block-content">
         <div class="input-box">
          <input onkeypress="handleKeyPress(event,this.form)" type="text" placeholder="Email address" name="email" id="newsletter" title="<?php echo $this->__('Subscribe to Our Newsletter') ?>" class="required-entry input-subscribe" style="width:178px;" />
          <div class="error-news-msg" id="error-news-msg" style="display:none;">Please enter a valid email address.</div>
        </div>
        <div class="actions">
            <div class="news-loader" id="news-loader" style="text-align:center; display:none;">
                <img src="<?php echo $this->getSkinUrl('images/news-loader.gif'); ?>" />
            </div>    
            <button type="button" title="<?php echo $this->__('Subscribe') ?>" onclick="myfunc();" class="button">
                 <span><span>Subscribe</span></span>
            </button>
        </div>
       </div>
    </form>    
</div>         

感谢您订阅我们的时事通讯！
这是一个常见的问题，似乎是针对Internet Explorer的

问题在于，按钮单击正在提交表单并触发onclick事件。这是两个不同的事件，表单提交似乎优先

要解决这个问题，您需要输入一个
返回false编码到onclick调用中：

<button type="button" title="<?php echo $this->__('Subscribe') ?>" onclick="myfunc(); return false;" class="button">

我让它工作了

我改变了：

<form name="newsletter-form" id="newsletter-form" method="post">

致：

然后改变了：

function myfunc()

<button type="button" title="<?php echo $this->__('Subscribe') ?>" onclick="myfunc();" class="button">

我加了一行：

var newsletterSubscriberFormDetail = new VarienForm('newsletter-form');

event.preventDefault();

打开：app/design/frontend/default/modern/template/newsletter/subscribe.phtml

创建此文件的一个备份，并用此代码替换它

一般来说，代码块的良好实践是只将相关的HTML放在一个块中，然后将相关的JS放在另一个块中。如果你没有包括足够的内容，你可能会被要求扩展它，但是粘贴在整个源代码中会使它不那么可读。我必须承认，我没有见过Chrome这样做。你试过这个改变了吗？我看不出这个改变有什么效果。
