Select multiple files to upload, display the upload speed, progress bar, pure FLASH code, and use the HTTP protocol, so the client and server do not need to install any components
Because it imitates FORM form submission, it supports all web dynamic languages: ASP PHP ASP.NET JSP, etc.
1. Fixed the bug that the trigger event after all files are uploaded will be triggered before the last file returns information.
2. In the event that all files are uploaded, add a return parameter to the JAVASCRIPT function challs_flash_onCompleteData to record the number of failed uploads.
