你也可以在Facebook回调的redirect_uri参数上指定你自己的散列，这在某些情况下可能是有帮助的，例如/api/account/callback#home。当你被重定向回来，它至少是一个哈希，对应于一个已知的路由，如果你使用backbone.js或类似的(不确定jquery移动)。

将此添加到我的重定向页面解决了我的问题…

if (window.location.href.indexOf('#_=_') > 0) {
    window.location = window.location.href.replace(/#.*/, '');
}

对于那些正在寻找简单答案的人 加上这个，对我很管用

if (window.location.hash === "#_=_"){
    history.replaceState 
        ? history.replaceState(null, null, window.location.href.split("#")[0])
        : window.location.hash = "";
}

博士TL;

if (window.location.hash === "#_=_"){
    history.replaceState 
        ? history.replaceState(null, null, window.location.href.split("#")[0])
        : window.location.hash = "";
}

完整版本与一步一步的说明

// Test for the ugliness.
if (window.location.hash === "#_=_"){

    // Check if the browser supports history.replaceState.
    if (history.replaceState) {

        // Keep the exact URL up to the hash.
        var cleanHref = window.location.href.split("#")[0];

        // Replace the URL in the address bar without messing with the back button.
        history.replaceState(null, null, cleanHref);

    } else {

        // Well, you're on an old browser, we can get rid of the _=_ but not the #.
        window.location.hash = "";

    }

}

循序渐进:

We'll only get into the code block if the fragment is #_=_. Check if the browser supports the HTML5 window.replaceState method. Clean the URL by splitting on # and taking only the first part. Tell history to replace the current page state with the clean URL. This modifies the current history entry instead of creating a new one. What this means is the back and forward buttons will work just the way you want. ;-) If the browser does not support the awesome HTML 5 history methods then just clean up the URL as best you can by setting the hash to empty string. This is a poor fallback because it still leaves a trailing hash (example.com/#) and also it adds a history entry, so the back button will take you back to #_-_.

了解更多关于历史的知识。

了解window.location的更多信息。

如果您想从url中删除剩余的“#”

$(window).on('load', function(e){
  if (window.location.hash == '#_=_') {
    window.location.hash = ''; // for older browsers, leaves a # behind
    history.pushState('', document.title, window.location.pathname); // nice and clean
    e.preventDefault(); // no page reload
  }
})
