Question

有没有办法将json对象的“路径”保存到变量？也就是说，如果我有这样的事情：

var obj = {"Mattress": {
                    "productDelivered": "Arranged by Retailer",
                    "productAge": {
                                "year": "0",
                                "month": "6"
                                }
                    }
       };

如何循环并将每个关键节点名称保存到变量？例如。（我需要这种格式）：床垫[productDelivered]，床垫[productAge] [年]，床垫[productAge] [月]

我已经部分地在这个小提琴中http://jsfiddle.net/4cEwf/，但正如你在日志中看到的那样，年份和月份不会分开，而是附加到数组中。我知道这是因为我已经进行了循环，但我仍然坚持如何进步以获得我需要的数据格式。我在小提琴中设置的流程正在模仿我需要的东西。

我有没有考虑过这样做？

Answer 1

尝试

var obj = {
    "Mattress": {
        "productDelivered": "Arranged by Retailer",
        "productAge": {
            "year": "0",
            "month": "6"
        }
    }
};

var array = [];

function process(obj, array, current){
    var ikey, value;
    for(key in obj){
        if(obj.hasOwnProperty(key)){
            value = obj[key];
            ikey = current ? current + '[' + key + ']' : key;
            if(typeof value == 'object'){
                process(value, array, ikey)
            } else {
                array.push(ikey)
            }
        }
    }
}
process(obj, array, '');
console.log(array)

var obj = {"Mattress": {
                    "productDelivered": "Arranged by Retailer",
                    "productAge": {
                                "year": "0",
                                "month": "6"
                                }
                    }
       };
var Mattress = new Array();
for(var i in obj.Mattress){
    if(typeof(obj.Mattress[i])==='object'){
        for(var j in obj.Mattress[i]){
            if(Mattress[i]!=undefined){
                Mattress[i][j] = obj.Mattress[i][j];
            }
            else{
                Mattress[i] = new Array();
                Mattress[i][j] = obj.Mattress[i][j];
            }
        }
    }
    else{
        Mattress[i] = obj.Mattress[i];
    }
}     
for(var i in Mattress){
    if(typeof(Mattress[i])==='object'){
        for(var j in Mattress[i]){
            alert(j+":"+Mattress[i][j]);
        }
    }
    else{
        alert(i+":"+Mattress[i]);
    }
}

通过递归将嵌套的json对象路径保存到变量
