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

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)
})

这个解决方案对我很有效:

function checkURLchange(){
    if(window.location.href != oldURL){
        alert("url changed!");
        oldURL = window.location.href;
    }
}

var oldURL = window.location.href;
setInterval(checkURLchange, 1000);

另一种简单的方法是通过添加一个单击事件，通过类名到页面上的锚标记来检测它何时被单击，然后您现在可以使用window.location.href来获取url数据，您可以使用这些数据来向服务器运行ajax请求。简单易行。

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});

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。
