我在手风琴中有3个表单，一个用于个人详细信息，账单信息和交付信息。如果在询问他们的账单和交付信息是否相同时选择了'yes'单选按钮，我想在交付信息部分自动填写表单。
我在网上找过了，似乎找不到任何关于在手风琴或同一页面上填写表格的内容。
下面是HTML:
详细信息 <img class="editcheckoutbtn" src="<?php echo ROOT; ?>/Images/Buttons/rentals_84x25_edit.png">
<div class="inputsection details">
<form id="detailsform">

<input type="email" name="email" />
<label for="contactnumber">Contact Number*</label>
<input type="text" name="contactnumber"/>
<p class="marketingtext">Do you wish to be contacted by Interski with future promotions?</p>

这是完全假设，正如您提到的手风琴，您的页面没有刷新
您可以简单地在您的Radio按钮上添加一个事件侦听器来访问必需的字段，然后使用它们来显示需要的地方。
也给你的输入字段适当的id
你可以这样做;
$("#deliveryyes").on('click',function(){
var firstaddress = $("#firstaddress").val();
...
// Use those values to populate other fields like
$("#delfirstaddress").val(firstaddress );
...
});
