The legacy PerformanceNavigation interface represents information about how the navigation to the current document was done.

An object of this type can be obtained by calling the Performance.navigation read-only attribute.

The PerformanceNavigation interface doesn't inherit any properties.

PerformanceNavigation.type Read only Deprecated

An unsigned short which indicates how the navigation to this page was done. Possible values are:

TYPE_NAVIGATE (0)

The page was accessed by following a link, a bookmark, a form submission, or a script, or by typing the URL in the address bar.

TYPE_RELOAD (1)

The page was accessed by clicking the Reload button or via the Location.reload() method.

TYPE_BACK_FORWARD (2)

The page was accessed by navigating into the history.

TYPE_RESERVED (255)

Any other way.

PerformanceNavigation.redirectCount Read only Deprecated

An unsigned short representing the number of REDIRECTs done before reaching the page.

The Performance interface doesn't inherit any methods.

PerformanceNavigation.toJSON() Deprecated

A serializer returning a JSON object representing the PerformanceNavigation object.

This feature is no longer on track to become a standard, as the Navigation Timing specification has marked it as deprecated. Use the PerformanceNavigationTiming interface instead.

• The Performance that allows access to an object of this type.
• PerformanceNavigationTiming (part of Navigation Timing Level 2) that has superseded this API.
