如何在骨干网中将数组转换为Collection [英] How to convert an array to Collection in backbone

问题描述

我有一个定义为的数组:

I have an array defined as:

this.noOfHouseHold = ["1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20"];

我正尝试将其转换为Backbone Collection，例如:

I'm trying to convert it to a Backbone Collection as:

var adultListCollection = new Backbone.Collection(this.noOfHouseHold);

它给出了我的列表，但对于2位数字，它显示如下内容:

It gives me the list but for 2 digit numbers, it shows something like this:

attributes: Object
0: "1"
1: "1"

我无法理解这里出了什么问题，或者是将数组转换为集合的错误方法.请提出建议.预先感谢！

I'm not able to understand as to what is wrong here or is it the wrong way I'm converting my array to collections. Please suggest. Thanks in advance!

推荐答案

Backbone集合需要一个模型/哈希表列表，这些列表可以转换为模型，但是您具有纯数组.

A Backbone collection expects a list of models/hashes of attributes that can be converted to a model but you have a plain array.

您将必须将数组转换为哈希列表.假设您的值是模型的id:

You will have to transform your array to a list of hashes. Assuming your values are the ids of your models :

var lst = _.map(this.noOfHouseHold, function(val) {
    return {id: val};
});
var adultListCollection = new Backbone.Collection(lst);
