bytesLoaded | property |
bytesLoaded:Number

ProgressEventExample
class to illustrate how various
event listeners are used when a file is being downloaded. The example carries out the following tasks:
- The properties
downloadURL
andfileName
are created, which indicate the location and name of the download file. - In the
ProgressEventExample
constructor, a new FileReference object namedfile
is created and then passed to theconfigureListeners()
method. - The
downloadURL
andfileName
properties are then passed tofile.download()
, which prompts for the location to download the file. - The
configureListeners()
method adds seven event listeners and their associated subscriber methods:cancel
/cancelHandler()
is dispatched if the file download is canceled.complete
/complereHandler()
is dispatched when the file download process is finished.ioError
/ioErrorHandler()
is dispatched if the download file is unavailable or inaccessible.open
/openHandler()
is dispatched when the download operation has started.progress
/progressHandler()
is dispatched when the download process begins and again when it ends.securityError
/securityErrorHandler
is dispatched if the local playback security setting does not match the type of data access for the download file (local versus network); see the notes below.select
/selectHandler()
is dispatched when the download object is selected.
Notes:
- You need to compile the SWF file with Local Playback Security set to Access Network Files Only.
- This example requires a file named SomeFile.pdf.
- Although this example makes use of all events available to the FileReference object, most situations require only a subset.
