The onpopstate property of the WindowEventHandlers mixin is the EventHandler for processing popstate events on the window.

A popstate event is dispatched to the window each time the active history entry changes between two history entries for the same document. If the activated history entry was created by a call to history.pushState(), or was affected by a call to history.replaceState(), the popstate event's state property contains a copy of the history entry's state object.

Note: Calling history.pushState() or history.replaceState() won't trigger a popstate event. The popstate event is only triggered by performing a browser action, such as clicking on the back button (or calling history.back() in JavaScript), when navigating between two history entries for the same document.

Syntax

window.onpopstate = funcRef;
  • funcRef is a handler function.

The popstate event

For example, a page at http://example.com/example.html running the following code will generate alerts as indicated:

window.onpopstate = function(event) {
  alert("location: " + document.location + ", state: " + JSON.stringify(event.state));
};

history.pushState({page: 1}, "title 1", "?page=1");
history.pushState({page: 2}, "title 2", "?page=2");
history.replaceState({page: 3}, "title 3", "?page=3");
history.back(); // alerts "location: http://example.com/example.html?page=1, state: {"page":1}"
history.back(); // alerts "location: http://example.com/example.html, state: null
history.go(2);  // alerts "location: http://example.com/example.html?page=3, state: {"page":3}

Note that even though the original history entry (for http://example.com/example.html) has no state object associated with it, a popstate event is still fired, when we activate that entry after the second call to history.back().

Browsers used to handle the popstate event differently on page load, but now they behave the same. Firefox never emitted a popstate event on page load. Chrome did until version 34, while Safari did until version 10.0.
