使用JQuery搜索JSON对象 [英] Searching JSON objects with JQuery

问题描述

我有以下JSON对象.使用JQuery，我需要找到以下值:

I have the following JSON object. Using JQuery I need to find the values of the following:

summary.nameValues.ID和detail.TypedNameValues.size

summary.nameValues.ID and detail.TypedNameValues.size

请问有人展示如何使用JQuery做到这一点吗?

Could somebody please show how this can be achieved using JQuery?

{
    "path": "\\Users\\john.smith\\test",
    "summary": {
        "NameValues": [
            {
                "Name": "Id",
                "Values": [
                    "232639"
                ]
            },
            {
                "Name": "City",
                "Values": [
                    "London"
                ]
            }
        ]
    },
    "detail": {
        "String": "some data",
        "Result": 0,
        "TypedNameValues": [
            {
                "Name": "name1",
                "Type": "string",
                "Value": "data here!!"
            },
            {
                "Name": "size",
                "Type": "long",
                "Value": "434353"
            }
        ]
    }
 }
]

推荐答案

jQuery不适用于普通对象文字.您可以类似的方式使用以下函数来搜索所有"id"(或任何其他属性)，而不管其在对象中的深度如何:

jQuery doesn't work on plain object literals. You can use the below function in a similar way to search all 'id's (or any other property), regardless of its depth in the object:

function getObjects(obj, key, val) {
    var objects = [];
    for (var i in obj) {
        if (!obj.hasOwnProperty(i)) continue;
        if (typeof obj[i] == 'object') {
            objects = objects.concat(getObjects(obj[i], key, val));
        } else if (i == key && obj[key] == val) {
            objects.push(obj);
        }
    }
    return objects;
}

使用方式如下:

getObjects(TestObj, 'id', 'A'); // Returns an array of matching objects
