这是我的解决方案:

function historyBack() {
  console.log('back');
  window.history.back() || window.history.go(-1);
  if (!window.history.length) window.close();
  var currentUrl = window.location.href;
  setTimeout(function(){
    // if location was not changed in 100 ms, then there is no history back
    if(current === window.location.href){
        console.log('History back is empty!');
    }
  }, 100);
}
function historyForward() {
  console.log('forward');
  window.history.forward() || window.history.go(+1);
  var current = window.location.href;
  setTimeout(function(){
    // if location was not changed in 100 ms, then there is no history forward
    if(current === window.location.href){
        console.log('History forward is empty!');
    }
  }, 100);
}

这是我的解决方案:

function historyBack() {
  console.log('back');
  window.history.back() || window.history.go(-1);
  if (!window.history.length) window.close();
  var currentUrl = window.location.href;
  setTimeout(function(){
    // if location was not changed in 100 ms, then there is no history back
    if(current === window.location.href){
        console.log('History back is empty!');
    }
  }, 100);
}
function historyForward() {
  console.log('forward');
  window.history.forward() || window.history.go(+1);
  var current = window.location.href;
  setTimeout(function(){
    // if location was not changed in 100 ms, then there is no history forward
    if(current === window.location.href){
        console.log('History forward is empty!');
    }
  }, 100);
}

这似乎很管用:

function goBackOrClose() {  

    window.history.back();
    window.close(); 

    //or if you are not interested in closing the window, do something else here
    //e.g. 
    theBrowserCantGoBack();

}

调用history.back()，然后调用window.close()。如果浏览器能够返回历史记录，它将无法到达下一条语句。如果无法返回，就会关闭窗口。

但是，请注意，如果已经通过输入url到达页面，那么firefox不允许脚本关闭窗口。

我找到了一个真正有效的JQuery解决方案

window.history.length == 1

这适用于Chrome, Firefox和Edge。 如果你想在没有窗口历史记录的情况下隐藏或删除网页上的后退按钮，你可以使用下面这段JQuery代码，它在上述3种浏览器的最新版本上都适用。

$(window).load(function() {
        if (window.history.length == 1) {
            $("#back-button").remove();
        }
    })

var func = function(){ console.log("do something"); };
if(document.referrer.includes(window.location.hostname) && history.length-1 <= 1){
    func();
}
else{
    const currentUrl = window.location.href;
    history.back();
    setTimeout(function(){
        currentUrl === window.location.href && func();
    }, 100);
}

我用的是window。在我的网站上的常见问题解答。

当用户想退出FAQ时，他们可以点击退出按钮(在后退按钮旁边)

我对这个“退出”策略的逻辑是基于入口ID，然后返回到该状态的状态数。

所以进入:

  enterState: { navigationId:number } = {navigationId: 1}

  constructor() {
    this.enterState = window.history.state
  }

假设用户正在浏览FAQ

然后，当用户单击退出按钮时，读取当前状态并计算delta:

exitFaq() {
    // when user started in faq, go back to first state, replace it with home and navigate
    if (this.enterState.navigationId === 1) {
      window.history.go((window.history.state.navigationId - 1) * -1)
      this.router.navigateByUrl('/')
      //  non-angular
      //  const obj = {Title: 'Home', Url: '/'}
      //  window.history.replaceState(obj, obj.Title, obj.Url)
    } else {
      window.history.go(this.enterState.navigationId - window.history.state.navigationId - 1)
    }
  }

如你所见，我还使用了一个回退当用户开始在faq，在这种情况下，状态。navigationId为1，我们想要路由回去，替换第一个状态，并显示主页(为此我使用Angular路由器，但你也可以使用历史记录。当你处理自己的路由时，也可以使用replaceState)

供参考:

history.go history.state history.replaceState Angular.router.navigateByUrl
