history.pushState does not trigger 'popstate' event

问题

Why

$(function () {
  $(window).bind('popstate', function () {alert('pop');});

  window.history.pushState(null, '', '/foo');
});

does not alert pop ?

NB: Testing on latest chrome

According to MDN:

A popstate event is dispatched to the window every time the active history entry changes. If the history entry being activated was created by a call to pushState or affected by a call to replaceState, the popstate event's state property contains a copy of the history entry's state object.

So why my pushState does not trigger the popstate event?

回答1:

The paragraph you reference is a little ambiguous. Reading the example on the same page, it is clear that popstate is only triggered when the user clicks the back button, not when the script calls pushState().

回答2:

You can manually trigger popstate event on window every time you call history.pushState().

history.pushState(state, '', url);

var popStateEvent = new PopStateEvent('popstate', { state: state });
dispatchEvent(popStateEvent);

回答3:

You are reading MDN's "guide page" which is not meant to be normative.

Consider reading MDN's "documentation page" for WindowEventHandlers.onpopstate instead:

Note that just calling history.pushState() or history.replaceState() won't trigger a popstate event. The popstate event is only triggered by doing a browser action such as a clicking on the back button (or calling history.back() in JavaScript). And the event is only triggered when the user navigates between two history entries for the same document.

Another undocumented way of triggering popstate is by direct manipulation of the window.location object.

// this also triggers popstate 
window.location.hash = "#some-new-hash"

My solution:

var url = "http://awesome.website.net/route/to/paradise";
window.history.pushState({}, "", url);
window.history.pushState({}, "", url); // yes twice
window.history.back();

It will trigger a soft-navigation via 'popstate' event and no HTTP request.

Document https://developer.mozilla.org/en-US/docs/Web/Events/popstate says:

Note that just calling history.pushState() or history.replaceState() won't trigger a popstate event. The popstate event will been triggered by doing a browser action such as a click on the back or forward button (or calling history.back() or history.forward() in JavaScript).

回答6:

I ran into this too... I think the event only fires if you have something at the top level of your data object that is distinct from the previous state.

Try this:

var data = {rand: Math.random()};
window.history.pushState(data, '', '/foo');

Don't know exactly what you where trying to achieve but if you simply want your popState Event Handler to launch you can simply extract it out to a function like below :

function popStateHandler(event) {
     // Event handling Code here
}
window.onpopstate = popStateHandler;

Then you can simply call your popStateHandler after you pushState.
