<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>jquery文件上傳</title>
<script type="text/javascript" src="jquery-1.7.2.js"></script>
<script type="text/javascript">
var addMore = function() {
var div = document.getElementById("div2");
var br = document.createElement("br");
var input = document.createElement("input");
var button = document.createElement("input");

input.setAttribute("type", "file");
button.setAttribute("type", "button");
button.setAttribute("value", "Remove");

button.onclick = function() {
div.removeChild(br);
div.removeChild(input);
div.removeChild(button);
}

div.appendChild(br);
div.appendChild(input);
div.appendChild(button);
}
//節點的移動
//$(function(){

//});
</script>
</head>

<body>
<div>
<input type="file"/>
<input type="button" value="more"/>
</div>
<div></div>
</body>

</html>

jquery實現

復制代碼代碼如下:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

//jquery實現文件上傳的按鈕添加和刪除
$(function(){
$("input[type=button]").click(function(){
var br = $("<br>");
var input = $("<input type='file'/>");
var button = $("<input type='button' value='Remove'/>");
$("#div1").append(br).append(input).append(button);

button.click(function() {
br.remove();
input.remove();
button.remove();
});
});
});
</script>

<body>
<div>
<input type="file"/>
<input type="button" value="more"/>
</div>
<div></div>
