尝试此操作，它将返回项目安娜和Julie

var data = [
            { id: 1, name: 'Anna', delivery: { city: "Amsterdam" }, invoice: { city: "Amsterdam" } },
            { id: 2, name: 'Anton', delivery: { city: "Amsterdam" }, invoice: { city: "Berlin" } },
            { id: 3, name: 'John', delivery: { city: "Berlin" }, invoice: { city: "Paris" } },
            { id: 4, name: 'Julie', delivery: { city: "Paris" }, invoice: { city: "Paris" } }
        ];

        var myStore = new Memory({ data: data, idProperty: 'id' });
        var myResultsSet = myStore.filter(function (object) {
            return object.delivery.city === object.invoice.city;
        });

        myResultsSet.forEach(function (item) {
            console.log("item ", item.name);
        });

基本上，您可以创建一个自己的函数传递给filter（），然后用它来编写自己的比较逻辑。

筛选（查询）
这会筛选集合，并传回新的子集集合。查询可以是对象或筛选对象，其属性会定义相符对象的条件约束。有些存放区（例如服务器或RQL存放区）可能会接受字串型查询。具有内存中功能的存放区（例如dstore/Memory）也可能会接受筛选函式，但使用筛选产生器可确保最大的跨存放区相容性。

EDIT：要比较多个属性的示例。您的函数只需要返回true或false（如果对象与比较条件匹配，则返回true）

var data = [
            { id: 1, name: 'Anna', delivery: { city: "Amsterdam", price: 5 }, invoice: { city: "Amsterdam", price: 20 } },
            { id: 2, name: 'Anton', delivery: { city: "Amsterdam", price: 8 }, invoice: { city: "Berlin", price: 7 } },
            { id: 3, name: 'John', delivery: { city: "Berlin", price: 10 }, invoice: { city: "Paris", price: 20 } },
            { id: 4, name: 'Julie', delivery: { city: "Paris", price: 2 }, invoice: { city: "Paris", price: 3  } }
        ];

        //example for custom filtering with nested properties
        var myStore = new Memory({ data: data, idProperty: 'id' });
        var myResultsSet = myStore.filter(function (object) {
            if(object.delivery.city === object.invoice.city){
                if (object.delivery.price < 5 && object.invoice.price < 5)
                    return true;
            }else
                return false;
        });

        myResultsSet.forEach(function (item) {
            console.log("item ", item.name);
        });
