Question

在使用此mixin构建的网站上切换按钮时，它会创建错误，即：bool

我添加了View和store文件，帖子如下。当我按下按钮时发生错误：＆＃34;注册＆＃34; ＆安培; ＆＃34;登录＆＃34;

但是在页面重新加载之后，它工作正常。我的SoreMixin文件如下：

Uncaught TypeError: store.off is not a function

存储文件：

/** @jsx React.DOM *//**
     * mixin to let components listen to stores in a simple way
     * the component needs to implement `onStoreUpdate` to set the state
     * @param {Object} store
     * @param {String} [events="add remove reset change"]
     */
    module.exports = function(store, events) {
        if(!events) {
            events = "add remove reset change";
        }
        return {
            componentDidMount: function() {
                store.on(events, function() {
                    this.forceUpdate();
                }, this);
            },
            componentWillUnmount: function() {
                store.off(null, null, this);
            }
        };
    };

查看文件：

var Backbone = require('backbone');
var Dispatcher = require('project/shared/dispatcher');

var baseStore = {
    /**
     * backbone init method
     */
    initialize: function() {
        this.dispatchId = Dispatcher.register(this.handleDispatch.bind(this));
    },

    /**
     * handle the dispatcher actions
     * @param {Object} payload
     */
    handleDispatch: function(payload) { }
};

module.exports =
{
    BaseStore : baseStore,
    Model: Backbone.Model.extend(baseStore),
    Collection: Backbone.Collection.extend(baseStore)
};

你商店里没有.off（）函数，这就是原因。

使用eventEmiter https://facebook.github.io/flux/docs/todo-list.html#creating-stores

阅读此示例

您将使用.on和removeListener（而不是.off（））

Flux：Uncaught TypeError：store.off不是函数
