我的记录或行在 PHP 的 while 循环中显示。我在所有记录之前都有一个“添加新的 href”链接。当用户按下“添加新”链接时，记录的克隆将复制到下面。管理员将根据他的意愿更改该记录。这是实际场景。
我已将我的脚本粘贴在下面。快完成了。但是，当我单击添加新 (+) 链接时，它会克隆文本框，但不会克隆行的值。那么我如何将文本框的值传递给javascript和jquery呢？

最佳答案
我已经编辑了您的代码，并且运行完美。试试这个:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<title>Clone</title>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript">
function addRow() {
var myRow = '<tr><td> <input type="text" id="p_new" name="data[]" value="some value" ></td></tr>';
$("#MyTable tr:last").after(myRow);
}
</script>
</script>
</head>
<body>
<div onclick="addRow()" style="color: Blue; text-decoration: underline;">
Add row to table
</div>
<table border="1" id="MyTable">
<tr>
<td id="addinput">
<input type="text" id="p_new" name="data[]" value="some value" >
</td>
</tr>
</table>
</body>
</html>
请告诉我您的问题是否解决。 干杯
