8 | Queue Plug-in |
---|
9 | |
---|
10 | Features: |
---|
11 | *Adds a cancelQueue() method for cancelling the entire queue. |
---|
12 | *All queued files are uploaded when startUpload() is called. |
---|
13 | *If false is returned from uploadComplete then the queue upload is stopped. |
---|
14 | If false is not returned (strict comparison) then the queue upload is continued. |
---|
15 | *Adds a QueueComplete event that is fired when all the queued files have finished uploading. |
---|
16 | Set the event handler with the queue_complete_handler setting. |
