4. Plupload v2.0.0
要想实现异步批量上传，大概有两种方式：隐藏iframe方式和flash控件。
而plupload是一个出色的批量上传插件，几乎不需要任何代码就可以实现一个漂亮的上传组件
它可以使用jqueryQueue、Jquery UI两种方式初始化，后者可以和Jquery UI结合实现风格的切换。
plupload最强大的地方在于你可以为它设置包括Flash、Silverlight、html4、html5、gears、browserplus等各种运行时环境，它会在初始化时逐个尝试，知道找到客户端支持的版本为止。也就是说，如果你按照
runtimes : 'gears,flash,silverlight,browserplus,html5,html4',
这样的方式来初始化的话，用chrome浏览器你会看到一个使用gears的版本，它能支持拖拽；在安装了flash控件的浏览器中是flash版本；在安装了silverlight的浏览器中看到的是silverlight版；如果都不支持的话会显示最基本的html4版，当然html4是不支持批量选择文件的，你只能将文件一个一个地加入到上传队列中。
plupload还能实现客户端文件类型和大小校验，超大文件自动分块(chunk)上传，自动生成唯一文件名(unique names)，客户端调整图片大小等强大的功能。
