我有一些我正在使用的代码,可以根据需要多次克隆 div 的内容。
原始代码将重命名每个表单字段的名称/ID。所以第一个克隆名称将是“name1”第二个克隆“name2”等......
问题是当我出于设计目的将表单字段放在 div 或表格中时。
代码不再重命名表单字段,因为它似乎指的是表或 div 的顶部元素(取决于我使用的)
这是包含此示例所需所有内容的代码的精简版本(可以复制到编辑器中并按原样工作。您将看到字段 id 没有被重命名):

<script type="text/javascript">
var formCounter = 0;
function init() {
document.getElementById('moreFields').onclick = moreFields;
moreFields();
}
function moreFields() {
formCounter++;
var newFields = document.getElementById('readroot').cloneNode(true);
newFields.id = '';
newFields.style.display = 'block';
var newField = newFields.childNodes;
for (var i=0;i<newField.length;i++) {
var theName = newField[i].name
if (theName)
newField[i].name = theName + formCounter;
}
var insertHere = document.getElementById('writeroot');
insertHere.parentNode.insertBefore(newFields,insertHere);
}
window.onload = moreFields;
</script>
<title>Add Orders IO TOC</title>
</head>
<body>
<!-- Template -->
<div id="readroot" style="display: none">
<table>
<tr><td colspan="2"><h3>Order <script>document.write(formCounter);</script></h2></td></tr>
<tr><td>Order ID: </td><td><input type="text" id="OrderID name="OrderID[]" ></input></td>
<td>Order Name: </td><td><input type="text" id="OrderName" name="OrderName[]" ></input></td>
</table>
<br /><br /><input type="button" value="Remove Above Order" style="width:200px;" onclick="this.parentNode.parentNode.removeChild(this.parentNode);" /><br /><br />
<!-- ROW -->
</div>
<!-- END Template -->
<!-- Start of form -->
<form method="get" action="form.php">
<table>
<tr><td align="center" colspan="2"><h2>Contract</h2></td></tr>
<!-- Static part of the form not to be cloned -->
<tr><td>Contract: </td><td><input type="text" id="Contract" name="Contract" ></input></td>
<td>Signed Date: </td><td><input type="text" id="datepicker0" name="SignedDate" ></input></td>
<tr><td align="center" colspan="2"><h2>Orders</h2></td></tr>

<!-- Cloned parts of the form appear here -->
<span id="writeroot"></span>

任何人都知道如何找到桌子的孩子吗?
谢谢!
