我遇到了此工作表單的問題。無論何時添加或刷新頁面,值都仍然存在。我相信這是因爲克隆方法從textBox中複製了value屬性。當我添加另一個文本框時,有什麼辦法可以擺脫它們嗎?在jQuery中使用克隆方法時擺脫textBox的Value屬性
<html>
<head>
<title>JQuery Example</title>
<script type="text/javascript" src="jquery-1.4.js"></script>
<script type="text/javascript">
function removeTextBox()
{
var childCount = $('p').size() //keep track of paragraph childnodes
//this is because there should always be 2 p be tags the user shouldn't remove the first one
if(childCount != 2)
{
var $textBox = $('#textBox')
$textBox.detach()
}
}
function addTextBox()
{
var $textBox = $('#textBox')
var $clonedTextBox = $textBox.clone()
//document.getElementById('textBox').setAttribute('value', "")
$textBox.after($clonedTextBox)
}
</script>
</head>
<body>
<form id =
method="POST"
action="http://cs.harding.edu/gfoust/cgi-bin/show">
<p id= "textBox">
Email:
<input type = "text" name="email" />
<input type ="button" value ="X" onclick = "removeTextBox()"/>
</p>
<p>
<a href="javascript:addTextBox()">Add another email</a>
</p>
<input type="submit" value="submit"/>
</form>
</body>
</html>
都能跟得上它不會在第二行代碼工作 – ProxyProtocol 2010-01-24 22:18:48
VaR的名稱應該是$ clonedTextBox,雖然我覺得在JS開始本地變量用$是一種不好的做法,尤其在與jQuery一起使用時會引起混淆...... – tfwright 2010-01-24 22:45:27
