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