unloadEventStart property

int get unloadEventStart

Warning: This interface of this property is deprecated in the Navigation Timing Level 2 specification. Please use the PerformanceNavigationTiming interface instead.

The legacy PerformanceTiming.unloadEventStart read-only property returns an unsigned long long representing the moment, in milliseconds since the UNIX epoch, the Window.unload_event event has been thrown. If there is no previous document, or if the previous document, or one of the needed redirects, is not of the same origin, the value returned is 0.

Implementation

external int get unloadEventStart;
