Get previous router/url in backbone application
提问by Roy M J
I have a backbone application and i would require to know the router from which the current route is accessed. Is it possible?
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。是否可以？
For eg :-
例如：-
I reach #/currentfrom #/test1and also in another instance, from #/test1.
我#/current从#/test1，在另一个例子中，从#/test1。
So can i know through some way to detect the previous router hit?
那么我可以通过某种方式知道检测以前的路由器命中吗？
Ive used :
我用过：
Backbone.history.fragment
and this only gives me the current route accessed and not from which route.
这只会给我当前访问的路线，而不是从哪条路线。

You can store your history in some array and do some manipulation with last/previous items.
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。
var history = [];
this.listenTo(this, 'route', function (name, args) {
history.push({
name : name,
args : args,
fragment : Backbone.history.fragment
});
console.log(history);
});
