onload | | A JavaScript function object that gets invoked when the operation is successfully completed. |
onloadend | nsIDOMEventListener | A JavaScript function object that gets invoked when the operation is completed for any reason; it will always follow a an abort, error, or load event. |
onloadstart | | A JavaScript function object that gets invoked exactly once when the operation begins. |
onprogress | | A JavaScript function object that gets invoked zero or more times, after the loadstart event, but before any abort, error, or load events occur. |
Handling the events
When the handler functions for these events are called, they receive as a parameter a ProgressEvent, which implements the nsIDOMProgressEvent interface.
