最终，Durandal的路由器插件正在设置document.title。

Ultimately Durandal's router plugin is setting the document.title.

https://github.com/dFiddle/dFiddle-1.2/blob/gh-pages/App/durandal/plugins/router.js#L254

onNavigationComplete: function (routeInfo, params, module) {
    if (app.title) {
        document.title = routeInfo.caption + " | " + app.title;
    } else {
        document.title = routeInfo.caption;
    }
},...

通常Durandal能够构造一个在路线对象上缺少标题属性，因此路线的设置方式可能有所不同。

Typically Durandal is able to construct a missing caption propterty on the route object, so maybe there's something different in the way the routes are set up.

https://github.com/dFiddle/dFiddle-1.2/blob/gh-pages/App/样本/shell.js#L6

router.map([

   { url: 'hello', moduleId: 'samples/hello/index', name: 'Hello World', visible: true },
   { url: 'hello/:name', moduleId: 'samples/hello/index', name: 'Examples' },...
]);
