window.onhashchange = function(){
    window.location.reload();
};

这页面要是不刷新，我才郁闷呢…

附上我之前写的一个简单的路由控制器

// 路由控制器
var RouterController = (function(){
    var hash = location.hash,
        routes,
        link = {};

    function Router(routes){
        this.routers = routes || {};
    }

    Router.prototype.register = function(name, callback){
        var self = this,
            flag = false,
            hash;

        for(var key in self.routers){
            if(self.routers[key] == name) {
                hash = key;
                flag = true;
                break;
            }
        }

        if(flag){
            link[hash] = callback;
        }
    };

    function RunHash(){
        var hash = location.hash,
            startStr, endStr;

        (hash.length > 1) ? (startStr = 1) : (startStr = 0);
        (hash.indexOf("?") > 0) ? (endStr = hash.indexOf("?")) : (endStr = hash.length);


        hash = hash.substring(startStr, endStr);

        for(var key in link){
            if(hash == key != 0){
                link[key].apply(null);
            }
        }
    }

    window.addEventListener('hashchange', RunHash);

    Router.prototype.start = function(){
        RunHash();
    };

    return Router;

})();

    // 实例化并注册页面中的路由数
  var router = new RouterController({
        "" : "home",
        "blog" : "blog"
    });

   // 注册回调函数

   router.register("blog", function(){
     console.log("this is blog");
    });


   router.register("home", function(){
       console.log("this is home");
   });
