使用静默Backbone.js的变更网址为previous [英] Silently change url to previous using Backbone.js

问题描述

使用Backbone.js的，是有可能使路由器导航到它是从哪里来的页面？我想利用它来进行，我改变我的URL的弹出窗口时的情况，我希望去改回来，当我隐藏弹出。我不想简单地回去，因为我要保持precisely相同的位置，在我离开之前，我发现弹出的背景页

Using Backbone.js, is it possible to make the router navigate to the page where it came from? I'd like to use that for the case where I change my URL when a popup appears, and I want go change it back, when I hide the popup. I don't want to simply go back, because I want to keep the background page in precisely the same position as I left it before I showed the popup

推荐答案

我通过扩展Backbone.Router类和存储我的所有路由解决了这个问题，而导航：

I solved this problem by extending Backbone.Router class and storing all my routes while navigate:

class MyRouter extends Backbone.Router
    constructor: (options) ->
        @on "all", @storeRoute
        @history = []
        super options

    storeRoute: ->
        @history.push Backbone.history.fragment

    previous: ->
        if @history.length > 1
            @navigate @history[@history.length-2], true 

然后，当你不得不解雇你的模式，只需调用 MyRouter。previous（）方法，它会将您重定向回最后一个哈希

Then, when you have to dismiss your modal, simply call the MyRouter.previous() method that it will redirect you back to the last "hash".
