我创建了这个与hashchange事件非常相似的事件

// onurlchange-event.js v1.0.1
(() => {
    const hasNativeEvent = Object.keys(window).includes('onurlchange')
    if (!hasNativeEvent) {
        let oldURL = location.href
        setInterval(() => {
            const newURL = location.href
            if (oldURL === newURL) {
                return
            }
            const urlChangeEvent = new CustomEvent('urlchange', {
                detail: {
                    oldURL,
                    newURL
                }
            })
            oldURL = newURL
            dispatchEvent(urlChangeEvent)
        }, 25)
        addEventListener('urlchange', event => {
            if (typeof(onurlchange) === 'function') {
                onurlchange(event)
            }
        })
    }
})()

使用示例:

window.onurlchange = event => {
    console.log(event)
    console.log(event.detail.oldURL)
    console.log(event.detail.newURL)
}

addEventListener('urlchange', event => {
    console.log(event)
    console.log(event.detail.oldURL)
    console.log(event.detail.newURL)
})

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});

在现代浏览器(IE8+， FF3.6+， Chrome)中，你可以只听窗口上的hashchange事件。

在一些旧的浏览器中，您需要一个计时器来持续检查location.hash。如果你正在使用jQuery，有一个插件可以做到这一点。

例子

下面我将撤销所有URL更改，以保持滚动:

<script type="text/javascript">
  if (window.history) {
    var myOldUrl = window.location.href;
    window.addEventListener('hashchange', function(){
      window.history.pushState({}, null, myOldUrl);
    });
  }
</script>

请注意，以上使用的历史api可用于Chrome, Safari, Firefox 4+和Internet Explorer 10pp4+

用jquery(和一个插件)就可以做到

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

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}`);
    }
});

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  
}
