Question

我正在尝试重置一个集合，但是当我这样做时，我收到以下错误，

未捕获的TypeError：无法读取属性＆＃39;原型＆＃39;未定义的

触发此重置的代码如下，

// Main object for the entire app

window.APP = {

config: {
    api: {
        base:'http://app.local/api/v1/',
    }
},

// Create this closure to contain the cached modules
module: function() {
    // Internal module cache.
    var modules = {};
    // Create a new module reference scaffold or load an
    // existing module.
    return function(name) {
        // If this module has already been created, return it.
        if(modules[name]) {
            return modules[name];
        }
        // Create a module and save it under this name
        modules[name] = { Views: {} };
        return modules[name];
    };
}(),

init: function() {

    // :: app start :: //
    var app = POPS;
    var Module = app.module( $( '#popsapp' ).data('route') );

    // Creates a Master object in the global namespace so data can be passed in from the DOM.
    // This would be replaced with a master Router if we weren't using actual pages
    app.Initialiser = function( initialCollection ) {
        this.start = function() {

            //don't cache ajax calls
            $.ajaxSetup({ cache: false });

            console.log(Module);

            if(Module.Collection !== undefined) {
                this.collection = new Module.Collection();
                this.view = new Module.Views.Master({ collection: this.collection });
            } else {
                this.view = new Module.Views.Master();  
            }

            if(this.collection !== undefined) {
                console.log(this.collection);
                console.log(initialCollection);
                console.log(this.collection.reset( initialCollection ));
                this.collection.reset( initialCollection );
            }

            //moved this here so script runs after the DOM has loaded.
            //but script.js still needs completely removing.
        };
    }; 
}

};

//进入应用程序的入口点 APP.init（）;

如果我在this.collection.reset( initialCollection)之前登录，则会在this.collection处触发错误。我可以看到一个空的集合。我试图创建我的集合的JSON如下，

json完全有效，我不确定问题是什么。有没有人有任何想法，它看起来像this.collection没有定义，这就是为什么我不能在它上面运行reset（），但我可以在登录时看到收藏品。

Answer 1

collection.reset()方法将Backbone模型数组作为输入。您的数组（initialCollection）只是一个通用的JavaScript数组。

this.collection.reset抛出错误 - 未捕获TypeError：无法读取未定义的属性'prototype'
