JAVASCRIPT使用ajax做异步上传文件,很流行的上传方式：代码如下
首先是HTML文档：
<!DOCTYPE html>
<html>
<head>
<meta name=”viewport” content=”width=device-width” />
<ｓｃｒｉｐｔ src=”~/ｓｃｒｉｐｔs/jquery-1.8.2.min.js”></ｓｃｒｉｐｔ>
<title>Index</title>
<ｓｃｒｉｐｔ>
$(function() {
$(‘:button’).click(function () {
var formData = new FormData();
var file = $(“input[type=’file’]”)[0].files[0];
formData.append(“files”, file);
$.ajax({
url: ‘/Upload/Upload’, //server ｓｃｒｉｐｔ to process data
type: ‘POST’,
//ajax事件处理
//beforeSend: beforeSendHandler,
//success: completeHandler,
//error: errorHandler,
// Form数据
data: formData,
cache: false,
contentType: false,
processData: false
});
});
});
</ｓｃｒｉｐｔ>
</head>
<body>
<form enctype=”multipart/form-data”>
<input name=”file” type=”file” multiple=”multiple” />
<input type=”button” value=”Upload” />
<input type=”text” name=”userName” value=”ice” />
</form>
</body>
</html>
