Question

我的数据包含一个具有嵌套对象的对象，每个键都是id，我想解析集合response.payload但是当我这样做时，集合将返回为包含嵌套对象的1个对象。任何人都可以建议我如何使每个嵌套对象成为一个模型？

JS

    var data = {
    "payload": {
        "020": {
            "sessions": ["SES1", "SES2", "SES3", "SES4"],
            "account": [],
            "tag": []
        },
        "650": {
            "sessions": ["SES11", "SES12", "SES13"],
            "account": ["ACCT1", "ACC2", "ACC3"],
            "tag": []
        },
        "880": {
            "sessions": ["SES900", "SES901"],
            "account": ["abc", "DEF"],
            "tag": ["TAG5", "TAG53"]
        }
    }
};

var SearchCollection = Backbone.Collection.extend({
    parse: function(response) {
        console.log(response.payload);
        return response.payload;
    }
});

var searchCollection = new SearchCollection(data, {parse: true});
console.log(searchCollection.toJSON());

我是否需要在解析中循环响应并使用密钥ID创建模型，或者创建模型并在那里进行一些解析？

我会“在解析中循环响应并使用密钥ID创建模型”。这是一种方法。

var SearchCollection = Backbone.Collection.extend({
    parse: function(response) {
      var models = [];
      _.each(response.payload,(value, key)=>{
        value.id = key;
        models.push(new Backbone.Model(value))
      })
        return models;
    }
});
