我想创建一个具有以下结构的 JSON 对象……我意识到 JSON 对象不应该有注释，但在这个例子中我只想解释所需的结构

selObj = {

    category: selectedCategory, // 1 category only

    catOptions:{
        optionValue:discountValue, // we can 1 or have many of paired keys in this sub object
        optionValue:discountValue,
        optionValue:discountValue
    },

    tariff:{
        tariffValue:discountValue, // we can 1 or have many of paired keys in this sub object
        tariffValue:discountValue
    },

    tarOptions:{
        tarOption:discountValue // we can 1 or have many of paired keys in this sub object

    }

};

现在我有一个函数可以填充我在脚本开头声明的空对象，如下所示……</p> 

$(document).ready(function() {
        var selObj = {}; 
        populateMyEmptyObject(selObj)

});

populateMyEmptyObject(emptyObject){

        emptyObject.category = "Category"

        // in my original function I have loops that produce strings with the following structure {"value1":"10","value2":"20","value3":"30","value4":"40"}, for this example I’ll call them loopReturn1,  loopReturn2, loopReturn3, loopReturn4

        // loops have happened and vars are produced... I've removed my loops as they're working just fine, I've omitted that code for simplicity

        emptyObject.catOptions = loopReturn1;
        emptyObject.tariff = loopReturn2;
        emptyObject.tarOptions = loopReturn3;
}

现在有了这个，我经常遇到空格问题等错误。有人告诉我应该使用JSON.stringify，但我仍然遇到问题。现在忘记循环，我应该如何获取生成的字符串并将它们附加到我的对象，有人可以告诉我获取字符串并将它们转换/解析为我的原始对象 selObj 的最佳实践。我还需要在我的函数中返回我的 emptyObject 以更新 selObj（如return emptyObject;）

我是否应该更改我原来的空对象，以便它更好地代表我想要的结构，如下所示：

var selObj = {

    "category": "selectedCategory",

    "catOptions":{
                },

    "tariff":{
              },

    "tarOptions":{
     }

};

任何建议都将不胜感激，我认为很明显我是一名自学成才的开发人员，而且我有一些坏习惯和知识漏洞！

例子

$(document).ready(function() {
    var o = getCategoryData(),
        sJSON = JSON.stringify(o);

    console.log(o, sJSON);
});

var getCategoryData = function(o) {

    // example functions start
    var getCategory = function() {
        return "Category";
    },
    getCatOptions = function() {
        return {value1: 10, value2: 20, value3: 30, value4: 40};
    },
    getTariff = function() {
        return {value1: 10, value2: 20, value3: 30, value4: 40};
    },
    getTarOptions = function() {
        return {value1: 10, value2: 20, value3: 30, value4: 40};
    };
    // example functions end

    if (!o) o = {};
    o.category = getCategory();
    o.catOptions = getCatOptions();
    o.tariff = getTariff();
    o.tarOptions = getTarOptions();
    return o;
}​
