appendChild()方法

我就直接贴代码了，大家去研究，时间紧，哈哈，见谅~

例一：

<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="./" /> 
<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> 
</form> 
</body> 
</html>

例二：

<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="./" /> 
<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> 
</form> 
</body> 
</html>
