popstate browser returns the event

When the activity history entry changes will trigger popstate event. If the history entry is activated by a call to history.pushState () created, or affected to history.replaceState () call, a copy of the state of the object of state property popstate events include historical items.

Note that the call history.pushState () or history.replaceState () does not trigger popstate event. In making the browser only action will trigger the event, such as the user clicks on the browser's back button (or Javascript code in the call history.back ())
