Parameters
fileRef:flash.net.FileReference - The File Reference object that initiated the
operation.
httpError:Number - The HTTP error that caused this upload to fail. For example, an
httpError of 404 indicates that a page is not found. HTTP error values can be found in
sections 10.4 and 10.5 of the HTTP specification at ftp://ftp.isi.edu/in-notes/rfc2616.txt.
Example
The following example creates a FileReference object with a listener for each possible event
including
onHttpError. This listener is triggered only if the upload fails because of an HTTP
error.
import flash.net.FileReference;
var listener:Object = new Object();
listener.onSelect = function(file:FileReference):Void {
trace("onSelect: " + file.name);
if(!file.upload("http://www.yourdomain.com/
yourUploadHandlerScript.cfm")) {
trace("Upload dialog failed to open.");
}
}
listener.onCancel = function(file:FileReference):Void {
trace("onCancel");
}
listener.onOpen = function(file:FileReference):Void {
trace("onOpen: " + file.name);
}
listener.onProgress = function(file:FileReference, bytesLoaded:Number,
bytesTotal:Number):Void {
trace("onProgress with bytesLoaded: " + bytesLoaded + " bytesTotal: " +
bytesTotal);
}
listener.onComplete = function(file:FileReference):Void {
trace("onComplete: " + file.name);
}
listener.onHTTPError = function(file:FileReference):Void {
trace("onHTTPError: " + file.name);
