Jquery 使用一组值解析JSON

我正在解析JSON

我得到了以下JSON（也描述了路径）

我得到了一个路径数组，如图所示

var patharray=[“冰淇淋”、“棍棒”、“冰霜”]

如何使用patharray中提到的上述路径动态搜索上述JSON

因此，上述PathArray的响应将是

 {
    "leaf": [
        {
            "id": "60",
            "has_topping": "1",
            "price": "75",
            "name": "Regular Stick, Frosty 70 Ml",
            "image": "/JSON_images/icecream_cup_vanilla.jpg",
            "Discount": 10,
            "has_crust": "0"
        }
    ]
}

我得到了一个通用的搜索函数（接受单个参数并重新返回值）

但问题是它无法识别路径，只返回第一个找到的路径

function isArray(what) {
    return Object.prototype.toString.call(what) === '[object Array]';
}

function isObject(what) {
    return Object.prototype.toString.call(what) === '[object Object]';
}

function addZeros(val) 
{
    val    = ""+val;
    return val.length === 1 ? "0"+val : val;
}

var results = [];
var cancel = false;



function recursiveSearch(name, json, startSaving, parentJson) {
    if (cancel) return;
    if (startSaving) {
        if (parentJson["leaf"]) {
            results.push("leaf");
            results.push(parentJson["leaf"]);
            cancel = true; //pushing leaf twice for somereason, work around with 'cancel'
            return;
        } else if (json["name"]) {
            results.push(json["name"]);
            return;
        } else if (json["leaf"]) {

            results.push(json["leaf"]);
            cancel = true; //pushing leaf twice for somereason, work around with 'cancel'
            return;
        }
    }
    if (isArray(json)) {
        for (var i = 0; i < json.length; i++) {
            recursiveSearch(name, json[i], startSaving, json);
        }
    } else {
        if (isObject(json)) {
            for (key in json) {
                if (key == "name") {
                    if (json[key] == name) {
                        startSaving = true;
                    }
                } else if (key == name) {
                    startSaving = true;
                }
                recursiveSearch(name, json[key], startSaving, json);
            }
        }
    }
}


function searchLeaf(name)
{


}

function search(name) {
    results = [];
    cancel = false;
    recursiveSearch(name, jsondata);

    return results;
}

函数isArray（什么）{
返回Object.prototype.toString.call（what）='[objectarray]'；
}
函数isObject（什么）{
返回Object.prototype.toString.call（what）=='[Object]'；
}
函数addZeros（val）
{
val=”“+val；
返回val.length==1？“0”+val:val；
}
var结果=[]；
var cancel=false；
函数递归搜索（名称、json、StartSave、parentJson）{
如果（取消）返回；
如果（开始保存）{
if（parentJson[“叶”]）{
结果：推（“叶”）；
结果：push（parentJson[“leaf”]）；
cancel=true；//出于某种原因推叶两次，使用“cancel”解决
返回；
}else if（json[“name”]）{
push（json[“name”]）；
返回；
}else if（json[“叶”]）{
push（json[“leaf”]）；
cancel=true；//出于某种原因推叶两次，使用“cancel”解决
返回；
}
}
if（isArray（json））{
for（var i=0；i

假设或我从问题中理解的内容-patharray中的元素位置取决于搜索路径

意思是-

“冰淇淋”->“棒状”->“冰霜”

var-patharray=[“冰淇淋”、“棍子”、“冰霜”]；
函数findElement（对象、路径数组、索引）{
var-res=''；
if（索引对于（var i=0；iIt看起来没有任何JSON，您拥有的是一个javascript对象！嗨，Harpreet，您能告诉我如何测试它吗？我的意思是什么是k.item在这种情况下？？您的完整对象是k，0是从pathArray开始搜索项的索引。在这种情况下，它将引用IceCream
