ProgressEvent that occurs when a read operation by an MSStreamReader or FileReader object successfully completes.

| Event Property | object.onload = handler; |
|---|---|
| addEventListener Method | object.addEventListener("onload", handler, useCapture) |
Event handler parameters

Type: function
Handler function to process the load event.
Remarks
If the operation fails, onload doesn't fire. Instead the onerror event fires and then the onloadend event fires.
When this event fires the lengthComputable property of the ProgressEvent is set to true. The length property of the ProgressEvent is set to the number of bytes read. The total property of the ProgressEvent is set to the number of bytes read and equals the value of the length property.
