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();

window.addEventListener("beforeunload", function (e) {
    // do something
}, false);

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

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)
})
