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});

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);

添加一个哈希更改事件侦听器!

window.addEventListener('hashchange', function(e){console.log('hash changed')});

或者，监听所有URL更改:

window.addEventListener('popstate', function(e){console.log('url changed')});

这比下面的代码要好，因为在window中只能存在一个东西。Onhashchange，你可能会覆盖其他人的代码。

// Bad code example

window.onhashchange = function() { 
     // Code that overwrites whatever was previously in window.onhashchange  
}

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

适用于Chrome 102+ (2022-05-24)

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