标题[问题] 用javascript在table里面新增表单
时间Thu Mar 29 20:43:15 2012
以下程式码可以正常运作
但是一旦我在符号QQ处加入table
程式就失效了
有大大可以帮我看一下吗
<html>
<head>
<title>My Test Page</title>
<script type="text/javascript">
<!--
var textNumber = 1;
function addTextBox(form, afterElement) {
// Increment the textbox number
textNumber++;
// Create the label
var label = document.createElement("label");
// Create the textbox
var textField = document.createElement("input");
textField.setAttribute("type","text");
textField.setAttribute("name","txt"+textNumber);
textField.setAttribute("id","txt"+textNumber);
// Add the label's text
label.appendChild(document.createTextNode("Text Box #"+textNumber+": "));
// Put the textbox inside
label.appendChild(textField);
// Add it all to the form
form.insertBefore(label,afterElement);
return false;
}
function removeTextBox(form) {
if (textNumber > 1) { // If there's more than one text box
// Remove the last one added
form.removeChild(document.getElementById("txt"+textNumber).parentNode);
textNumber--;
}
}
//-->
</script>
<style type="text/css">
<!--
label {
display:block;
margin:.25em 0em;
}
-->
</style>
</head>
<body>
<form id="myForm" method="get" action="./" >
QQ <table><tr><td>
<label>Text Box #1: <input type="text" name="txt1" id="txt1" /></label>
<p>
<input type="button" value="Add Textbox" onclick="addTextBox(this.form
,this.parentNode)" />
<input type="button" value="Remove Textbox"
onclick="removeTextBox(this.form)" />
</p>
<p><input type="Submit" value="Submit" /></p>
QQ </td></tr></table>
</form>
</body>
</html>
