这段代码是完整的javascript。 把这个放在你的主页或者其他你需要的地方当有人返回时，它会把他们带到他们之前所在的页面。

<script type="text/javascript"> 
        function preventBack() { 
            window.history.forward();  
        } 
          
        setTimeout("preventBack()", 0); 
          
        window.onunload = function () { null }; 
    </script>

非常简单和干净的函数打破向后箭头，而不干扰页面之后。

好处:

Loads instantaneously and restores original hash, so the user isn't distracted by URL visibly changing. The user can still exit by pressing back 10 times (that's a good thing), but not accidentally No user interference like other solutions using onbeforeunload It only runs once and doesn't interfere with further hash manipulations in case you use that to track state Restores original hash, so almost invisible. Uses setInterval, so it doesn't break slow browsers and always works. Pure JavaScript, does not require HTML5 history, works everywhere. Unobtrusive, simple, and plays well with other code. Does not use unbeforeunload which interrupts user with modal dialog. It just works without fuss.

注意:其他一些解决方案使用onbeforeunload。请不要为此目的使用onbeforeunload，当用户试图关闭窗口、点击反向箭头等时，onbeforeunload会弹出一个对话框。像onbeforeunload这样的情态动词通常只适用于很少的情况，比如当它们实际上在屏幕上做了更改并且没有保存它们时，不是为了这个目的。

工作原理

在页面加载时执行 保存您的原始散列(如果URL中有一个)。 依次追加#/noop/{1..10}到哈希 恢复原始哈希

就是这样。没有更多的混乱，没有后台事件监控，没有其他。

在一秒钟内使用它

要部署，只需在页面或JavaScript代码中添加这个:

<script>
    /* Break back button */
    window.onload = function(){
      var i = 0;
      var previous_hash = window.location.hash;
      var x = setInterval(function(){
        i++;
        window.location.hash = "/noop/" + i;
        if (i==10){
          clearInterval(x);
          window.location.hash = previous_hash;
        }
      }, 10);
    }
</script>

如何阻止反向功能:

历史。pushState(null, null, location.href); 窗口。Onpopstate = function () { history.go (1); };

在Chrome 79中，被点赞最多的答案没有一个对我有效。看起来Chrome在75版之后改变了后退按钮的行为。在这里看到的:

https://support.google.com/chrome/thread/8721521?hl=en

然而，在谷歌的帖子中，Azrulmukmin Azmi在最后提供的答案确实起作用了。这是他的解。

<script>
    history.pushState(null, document.title, location.href);
    history.back();
    history.forward();
    window.onpopstate = function () {
        history.go(1);
    };
</script>

Chrome的问题是它不会触发onpopstate事件 除非你做出浏览器动作(即调用history.back)。这就是为什么 我已经将这些添加到脚本中。

我不完全明白他写了什么，但显然现在需要一个额外的history.back() / history.forward()来阻止Chrome 75+中的返回。

我遇到了这个问题，需要一个在各种浏览器上正确工作的解决方案，包括Mobile Safari(在发布时是iOS 9)。没有一个解决方案是完全正确的。我提供以下建议(在Internet Explorer 11、Firefox、Chrome和Safari上进行了测试):

history.pushState(null, document.title, location.href);
window.addEventListener('popstate', function (event)
{
  history.pushState(null, document.title, location.href);
});

注意事项:

history.forward() (my old solution) does not work on Mobile Safari --- it seems to do nothing (i.e., the user can still go back). history.pushState() does work on all of them. the third argument to history.pushState() is a url. Solutions which pass a string like 'no-back-button' or 'pagename' seem to work OK, until you then try a Refresh/Reload on the page, at which point a "Page not found" error is generated when the browser tries to locate a page with that as its URL. (The browser is also likely to include that string in the address bar when on the page, which is ugly.) location.href should be used for the URL. the second argument to history.pushState() is a title. Looking around the web most places say it is "not used", and all the solutions here pass null for that. However, in Mobile Safari at least, that puts the page's URL into the history dropdown the user can access. But when it adds an entry for a page visit normally, it puts in its title, which is preferable. So passing document.title for that results in the same behaviour.

这里的一些解决方案不会阻止回退事件的发生——它们让回退事件发生(浏览器内存中关于页面的数据丢失)，然后它们播放一个向前事件，试图隐藏回退事件刚刚发生的事实。如果页面处于暂时状态，则该方法将不成功。

我为React写了这个解决方案(当React路由器不被使用时)，它是基于vrfvr的答案。

它将真正阻止后退按钮做任何事情，除非用户确认弹出:

  const onHashChange = useCallback(() => {
    const confirm = window.confirm(
      'Warning - going back will cause you to loose unsaved data. Really go back?',
    );
    window.removeEventListener('hashchange', onHashChange);
    if (confirm) {
      setTimeout(() => {
        window.history.go(-1);
      }, 1);
    } else {
      window.location.hash = 'no-back';
      setTimeout(() => {
        window.addEventListener('hashchange', onHashChange);
      }, 1);
    }
  }, []);

  useEffect(() => {
    window.location.hash = 'no-back';
    setTimeout(() => {
      window.addEventListener('hashchange', onHashChange);
    }, 1);
    return () => {
      window.removeEventListener('hashchange', onHashChange);
    };
  }, []);
