版本：Uploadify Version 3.2
官网：http://www.uploadify.com
Uploadify是一款基于Jquery的上传插件，用起来很方便。但上传过程中的提示语言为英文，这里整理下如何修改英文为中文提示。
方法1：直接修改uploadify.js中的提示信息，将英文提示改成对应的中文。不过从软件设计的角度来说，直接修改原类库不是最好的解决方案，会影响到软件的升级。
方法2：重写Uploadify事件
'overrideEvents' : [ 'onDialogClose', 'onUploadError', 'onSelectError' ]
当重写onDialogClose事件后，Uploadify的错误提示信息就都不会提示了。提示信息可直接自定义弹出。
重写事件errorCode的定义在js库中都可以找到。也可以直接用this.queueData.errorMsg来改变提示信息

说明：由于FLASH的BUG导致在FF中上传时获取不到SESSION，可以使用formData来传值，如：
|
1
|
formData : { '<?php echo session_name();?>' : '<?php echo session_id();?>' }
