下面的答案来自这里(使用旧的javascript语法(没有箭头函数，支持IE 10+)): https://stackoverflow.com/a/52809105/9168962

(function() {
  if (typeof window.CustomEvent === "function") return false; // If not IE
  function CustomEvent(event, params) {
    params = params || {bubbles: false, cancelable: false, detail: null};
    var evt = document.createEvent("CustomEvent");
    evt.initCustomEvent(event, params.bubbles, params.cancelable, params.detail);
    return evt;
  }
  window.CustomEvent = CustomEvent;
})();

(function() {
  history.pushState = function (f) {
    return function pushState() {
      var ret = f.apply(this, arguments);
      window.dispatchEvent(new CustomEvent("pushState"));
      window.dispatchEvent(new CustomEvent("locationchange"));
      return ret;
    };
  }(history.pushState);
  history.replaceState = function (f) {
    return function replaceState() {
      var ret = f.apply(this, arguments);
      window.dispatchEvent(new CustomEvent("replaceState"));
      window.dispatchEvent(new CustomEvent("locationchange"));
      return ret;
    };
  }(history.replaceState);
  window.addEventListener("popstate", function() {
    window.dispatchEvent(new CustomEvent("locationchange"));
  });
})();

看看jQuery的卸载函数。它能处理所有的事情。

https://api.jquery.com/unload/

当用户导航离开页面时，卸载事件被发送到窗口元素。这可能意味着许多事情之一。用户可以点击一个链接离开页面，或者在地址栏中输入一个新的URL。前进和后退按钮将触发事件。关闭浏览器窗口将触发该事件。即使是重新加载页面也会首先创建卸载事件。

$(window).unload(
    function(event) {
        alert("navigating");
    }
);

用jquery(和一个插件)就可以做到

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

http://benalman.com/projects/jquery-hashchange-plugin/

否则，你必须使用setInterval并检查哈希事件的变化(window.location.hash)

更新!一个简单的草稿

function hashHandler(){
    this.oldHash = window.location.hash;
    this.Check;

    var that = this;
    var detect = function(){
        if(that.oldHash!=window.location.hash){
            alert("HASH CHANGED - new has" + window.location.hash);
            that.oldHash = window.location.hash;
        }
    };
    this.Check = setInterval(function(){ detect() }, 100);
}

var hashDetection = new hashHandler();

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}`);
    }
});

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)
})

当点击链接将你重定向到同一域名的不同页面时，这些似乎都不起作用。因此，我提出了自己的解决方案:

let pathname = location.pathname;
window.addEventListener("click", function() {
    if (location.pathname != pathname) {
        pathname = location.pathname;
        // code
    }
});

编辑:您还可以检查popstate事件(如果用户返回一个页面)

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

最好的祝愿,
