window.addEventListener("beforeunload", function (e) {
    // do something
}, false);

适用于Chrome 102+ (2022-05-24)

navigation.addEventListener("navigate", e => {
  console.log(`navigate ->`,e.destination.url)
});

享受吧!

var previousUrl = '';
var observer = new MutationObserver(function(mutations) {
  if (location.href !== previousUrl) {
      previousUrl = location.href;
      console.log(`URL changed to ${location.href}`);
    }
});

window.onhashchange = function() { 
     //code  
}

window.onpopstate = function() { 
     //code  
}

or

window.addEventListener('hashchange', function() { 
  //code  
});

window.addEventListener('popstate', function() { 
  //code  
});

与jQuery

$(window).bind('hashchange', function() {
     //code
});

$(window).bind('popstate', function() {
     //code
});

在一个单独的线程中找到了一个工作答案:

没有一个事件是永远有效的，对于大多数大型spa来说，monkey patch pushState事件是非常偶然的。

所以聪明的投票对我来说是最有效的。您可以添加任意多的事件类型，但这些似乎对我来说做得很好。

为TS编写，但很容易修改:

const locationChangeEventType = "MY_APP-location-change";

// called on creation and every url change
export function observeUrlChanges(cb: (loc: Location) => any) {
  assertLocationChangeObserver();
  window.addEventListener(locationChangeEventType, () => cb(window.location));
  cb(window.location);
}

function assertLocationChangeObserver() {
  const state = window as any as { MY_APP_locationWatchSetup: any };
  if (state.MY_APP_locationWatchSetup) { return; }
  state.MY_APP_locationWatchSetup = true;

  let lastHref = location.href;

  ["popstate", "click", "keydown", "keyup", "touchstart", "touchend"].forEach((eventType) => {
    window.addEventListener(eventType, () => {
      requestAnimationFrame(() => {
        const currentHref = location.href;
        if (currentHref !== lastHref) {
          lastHref = currentHref;
          window.dispatchEvent(new Event(locationChangeEventType));
        }
      })
    })
  });
}

使用

observeUrlChanges((loc) => {
  console.log(loc.href)
})

经过一番研究后编辑:

不知怎么的，我似乎被Mozilla文档上的文档愚弄了。当代码中调用pushState()或replaceState()时，popstate事件(及其回调函数onpopstate)不会被触发。因此，原来的答案并不适用于所有情况。

然而，有一种方法可以绕过这个问题，根据@alpha123对函数进行猴子补丁:

var pushState = history.pushState;
history.pushState = function () {
    pushState.apply(history, arguments);
    fireEvents('pushState', arguments);  // Some event-handling function
};

原来的答案

假设这个问题的标题是“如何检测URL更改”，当你想知道完整路径更改(而不仅仅是哈希锚)时，答案是你可以监听popstate事件:

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

在Mozilla Docs中引用popstate

目前(2017年1月)全球92%的浏览器支持popstate。
