流星集合中的数字字段名称 [英] Numeric field names in meteor collection

问题描述

我需要实现这样的集合结构:

I need to achieve such collection structure:

{
    "_id" : "36JaTS8N9uJDHabaq",
    "pages" : {
        1 : {
            "field1" : "value1",
            "field2" : "value2"
        },
        ...
    }
}

一切都很好，当我执行以下操作时:

Everything is fine, when I'm doing the following:

Collection.insert({
    "pages": {
        1: {
            "field1" : "value1",
            "field2" : "value2"
        }
    }
})

但是当我尝试使用包含数字的变量而不是数字本身时，例如:

But when I'm trying to use the variable containing the number instead of number itself, like:

var number = 1;
Collection.insert({
    "pages": {
        number: {
            "field1" : "value1",
            "field2" : "value2"
        }
    }
})

我没有收到我想要的结果(数字应该是变量名):

I receive not the result I want (there is a variable name where number should be):

{
    "_id" : "SjMotZHrtXviuoyqv",
    "pages" : {
        "number" : {
            "field1" : "value1",
            "field2" : "value2"
        }
    }
}

完成我正在努力实现的目标的正确方法是什么?

What is the right way to do what I'm trying to achieve?

提前致谢！

推荐答案

在 JavaScript 中，您不能将变量用作对象字面量的键.见 这个答案.

You can't use variables as keys in object literals in javascript. See this answer.

var number = 1;
var pages = {};
pages[number] = {f1: 'v1', f2: 'v2'};
Collection.insert({pages: pages});
