我在网站上有 2 个注册表单。一个位于顶部，以模式打开，是一个多步骤表单，从输入电子邮件地址开始。该表单的代码如下:

接下来，我在网站底部有第二个注册表单，用于号召性用语，其中只有电子邮件输入，单击按钮时会打开第二个表单的模式。该表单的代码如下:
<form action="sendform.php" method="post" name="contact-form" class=" indline-form" id="main-contact-form">
<div class="form-group">
<input type="email" name="signupemail" id="bottomemail" required="required" class="form-control" value="Enter your email address..."
onfocus="(this.value == 'Enter your email address...') && (this.value = '')"
onblur="(this.value == '') && (this.value = 'Enter your email address...')" />
<button required="required" class="btn btn-arrow"><a href="#" data-toggle="modal" data-target="#signup-modal" id="bottom_form_submit" class="modal-toggle">Subscribe</a></button>
</div>
</form>
现在我的问题是，是否有任何 JQuery 或 javascript 可用于从底部注册表单的电子邮件输入字段中获取值并将其放入顶部电子邮件输入字段模态的注册表单中？
最佳答案
你试过吗？
jQuery('#email_address').val(jQuery('#bottomemail').val());
关于javascript - 我怎样才能从一个表单的输入字段中获取数据，并使用它来使用 JQuery 以不同的表单填充相同的输入类型？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36719599/
