Backbone.js的：获取当前路径 [英] Backbone.js: get current route

问题描述

使用骨干，是否有可能对我来说，得到当前路由的名称？我知道如何绑定到路由变化事件，但我希望能够确定在其他时间目前的路线，在变化的。

Using Backbone, is it possible for me to get the name of the current route? I know how to bind to route change events, but I'd like to be able to determine the current route at other times, in between changes.

推荐答案

如果您在您的应用程序实例化一个路由器，下面一行返回当前片段：

If you have instantiated a Router in your application, the following line returns the current fragment:

Backbone.history.getFragment();

从 Backbone.js的文档：

[...]
历史作为全球路由器（每帧）来处理hashchange事件或pushState的，匹配合适的路由，并触发回调。你不应该曾经有创建这些自己的一个 - 的你应该使用将为创建的参考Backbone.history您自动的如果您使用路由器与路线。
[...]

" [...] History serves as a global router (per frame) to handle hashchange events or pushState, match the appropriate route, and trigger callbacks. You shouldn't ever have to create one of these yourself — you should use the reference to Backbone.history that will be created for you automatically if you make use of Routers with routes. [...]"

如果您需要绑定到该片段函数的名称，就可以让这样的事情你的路由器的域内：

If you need the name of the function bound to that fragment, you can make something like this inside the scope of your Router:

alert( this.routes[Backbone.history.getFragment()] );

或者这样从路由器之外的：

Or like this from outside your router:

alert( myRouter.routes[Backbone.history.getFragment()] );
