在主干应用程序中获取以前的路由器/url [英] Get previous router/url in backbone application

问题描述

我有一个主干应用程序，我需要知道访问当前路由的路由器.可能吗?

I have a backbone application and i would require to know the router from which the current route is accessed. Is it possible?

例如:-

我从 #/test1 到达 #/current，在另一个例子中，也从 #/test1.

I reach #/current from #/test1 and also in another instance, from #/test1.

那么我可以通过某种方式知道检测以前的路由器命中吗?

So can i know through some way to detect the previous router hit?

我用过:

Backbone.history.fragment

这只会给我当前访问的路线，而不是从哪条路线.

and this only gives me the current route accessed and not from which route.

推荐答案

您可以将历史记录存储在某个数组中，并对上一个/上一个项目进行一些操作.

You can store your history in some array and do some manipulation with last/previous items.

var history = [];
this.listenTo(this, 'route', function (name, args) {
  history.push({
    name : name,
    args : args,
    fragment : Backbone.history.fragment
  });
  console.log(history);
});
