最近在网上下了个flash的代码实现批量上传功能的
然后所有的问题我都解决了现在剩下的问题就是我获取上传文件名的时候,有的时候能全部正确获取,
有的时候却只能获取到其中一部分文件的名字,还有一部分文件的名字不能正常获取,
小弟在这里贴出flash的action代码,还有响应flash是想上传的asp.net代码,求各位大哥们兄弟们帮帮忙
告诉我怎么正确的获取这个flash传给后台的文件名。

Adding the flash uploader to the page. <param name="wmode" value="transparent"> makes

FlashVars is set to pass in the upload page and a javascript function if desired.
The javascript function fires when the upload is completed. This allows us to
call a codebehind function to refresh a gridView or anything else.
A link button is used to perform this function. The javascript is added in the pageLoad

To edit the flash file, Adobe/Macromedia has a 30-day trial of Macromedia Flash

这是个jquery批量上传插件..你看看
现在我不是要提交给客户,是要提交给我们老大~~~~,我要崩溃了29号回家的火车票啊明天还没弄出来就回不了家了
不管你能不能听懂我 直接给你说我的问题了,
现在是我能从flash中获取到上传的文件名,但是我在后台需要将这个文件名再获取一次,就这里出问题,我再获取这个文件名的时候就有问题了,要么就少获取几个要么就获取了上次提交的文件名,有的时候还是能正确获取的。
我的问题就这里,不知道大哥们碰到过没有
