2.  标准化api 属性

Fld 指定回填的 textbox 名称

callbackQ11 默认回答函数

Callback  指定回调函数

3.  实现原理 利用 FormData 对象,你可以使用一系列的键值对来模拟一个完整的表单,然后使用 XMLHttpRequest 发送这个"表单".

这个是 XMLHttpRequest 2.0 提供的一个类

你还可以使用jQuery来发送 FormData,但必须要正确的设置相关选项 :

4.  如果需要显示进度条,实时显示文件上传进度 需要使用Ajaxj技术 ..up到个在的iframe黑头.. 工作原理 其实际就是在处理上传文件的同时,将上传进度的信息例如文件总长吨,已经上传多少,传输速率写入session中,客户端游览器 利用Ajax技术再新开一个独立的进程从session中获取上传进度信息,并实时显示,Ajax技术能够 不刷新页面获取服务器数据。session 可看做是服务器内存,可以用于存放少量的客户信息。

上传监听器 commons-fileupload版1.2支持上传监听,只需要实现一个监听器,并把它添加到上传组件上即可。监听器需要实现它的progresslistener

5. Php 的实现

这个临时的复制文件会在脚本结束时消失。要保存被上传的文件,我们需要把它拷贝到另外的位置:

if (isset($_POST['upload'])) { 

var_dump($_FILES);

//// 第三个参数是“ true ”表示能创建多级目录, iconv 防止中文目录乱码

// $res=mkdir(iconv("UTF-8", "GBK", $path),0777,true); 

$f=dirname(__FILE__).'/up_tmpx2/'.time().'.jpg';

mkdir(dirname( $f),0777,true);  move_uploaded_file($_FILES['upfile']['tmp_name'], $f);

//header('location: test.php');

exit;

5.1. Java 与 php 的不同点

Php 需要 move 内存文件到临时文件

Jva 的直接 stream 写入
