虽然这是一个老问题，但位置栏项目非常有用。

var LocationBar = require("location-bar");
var locationBar = new LocationBar();

// listen to all changes to the location bar
locationBar.onChange(function (path) {
  console.log("the current url is", path);
});

// listen to a specific change to location bar
// e.g. Backbone builds on top of this method to implement
// it's simple parametrized Backbone.Router
locationBar.route(/some\-regex/, function () {
  // only called when the current url matches the regex
});

locationBar.start({
  pushState: true
});

// update the address bar and add a new entry in browsers history
locationBar.update("/some/url?param=123");

// update the address bar but don't add the entry in history
locationBar.update("/some/url", {replace: true});

// update the address bar and call the `change` callback
locationBar.update("/some/url", {trigger: true});

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");
    }
);

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"));
  });
})();

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,

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}`);
    }
});
