javascript - 主干路由器导航到 .../#/ 而不触发路由器事件。如何？

Question

不知道如何强制 Backbone 正确导航到这样的路线:

page/#/channel/name

代替

page#channel/name

或

page#/channel/name

我的路由器使用一个主要模型并观察其状态，因此在这种情况下路由器应该能够更改 URL 而无需触发其事件。

我试过这样做:

router.navigate("#/channel/" + encodeURIComponent(appState.data.channelName), { trigger: false });

但在这种情况下，“trigger: false”不起作用，所以我收到了不希望的路由器事件调用。

Backbone.history root 设置为“/”，我目前没有使用 pushState。

参见下面的代码示例:

var Router = Backbone.Router.extend({
    routes: {
        "": "index",            
        "index": "index",
        "channel/:channelName": "changeChannel"
    },

    initialize: function (options) {
        var router = this;

        if (options.model) {
            router.model = options.model;
        } else {
            //TODO: throw error
            return;
        }

        //update url in cases of model channelSelection changes
        router.model.on("stateChangeAccepted", function (appState) {
            switch (appState.mode) {
                case "channel":
                    router.navigate("/channel/" 
                        + encodeURIComponent(appState.data.channelName), { trigger: false });
                    break;                    
            }
        });
    },

    index: function () {
        var router = this;

        router.model.trigger("stateChangeRequest", {
            mode: "channel",
            data: {
                channelIndex: 0
            }
        });

    },

    changeChannel: function (channelName) {
        var router = this;

        router.model.trigger("stateChangeRequest", {
            mode: "channel",
            data: {
                channelName: decodeURIComponent(channelName)
            }
        });

    }
});

您的 router.navigate 调用与您定义的路由不匹配:

routes: {
  "": "index",            
  "index": "index",
  "channel/:channelName": "changeChannel"
},

这意味着 channel 的 URL 应该是 http://host.com/#channel/someChannel。但是，您的 router.navigate 调用是 router.navigate('#/channel...) 或 router.navigate('/channel...)。应该是:

router.navigate("channel/" + encodeURIComponent(appState.data.channelName), { trigger: false });

但是，如果您想使用像 http://host.com/#/channel/someChannel 这样的路由，那么您的路由应该是:

routes: {
  "": "index",            
  "index": "index",
  "/channel/:channelName": "changeChannel"
},

你的导航调用应该是:

router.navigate("/channel/" + encodeURIComponent(appState.data.channelName), { trigger: false });
