为了增加更多的选择，还有XPath。XPath 3.1处理JSON和XML。在XPath 3.1中，您需要的查询是?0?Objects?*[?id = 3)

JMESPath是一个非常成熟的库，具有详细的规范和对多种语言的支持。

语法的例子:

// Select a single item
people[1].firstName

// Select a slice of an array
people[0:5]

// Select all the first names
people[*].firstName

// Select all first names based on search term
people[?state=='VA'].firstName

// Count how many people are over 35
length(people[?age>`35`])

// Select only the name and age of people over 35
people[?age>`35`].{name: name, age: age}

// Join expressions together to sort and join elements into a string
people[?state == 'WA'].name | sort(@) | join(', ', @)

在文档中还有更多的实例可以使用。

JS库精简了19kb，因此可能比某些库大，但考虑到广泛的特性，您可能会发现它值得。

其他选项

还有一些用于遍历/过滤JSON数据的其他选项，以及一些语法示例，以帮助您进行比较…

JSPath .automobiles{。maker ===“本田”&& .year > 2009}.model json:select()(更多的灵感来自CSS选择器) .automobile .maker:val("Honda") .model JSONPath(更多地受XPath启发) 美元.automobiles [? (@.maker =“本田”)]得

js看起来也很酷，这里有一个简单的例子:

var obj = {
        "car": [
            {"id": 10, "color": "silver", "name": "Volvo"},
            {"id": 11, "color": "red",    "name": "Saab"},
            {"id": 12, "color": "red",    "name": "Peugeot"},
            {"id": 13, "color": "yellow", "name": "Porsche"}
        ],
        "bike": [
            {"id": 20, "color": "black", "name": "Cannondale"},
            {"id": 21, "color": "red",   "name": "Shimano"}
        ]
    },
    search = JSON.search(obj, '//car[color="yellow"]/name');

console.log( search );
// ["Porsche"]

var reds = JSON.search(obj, '//*[color="red"]');

for (var i=0; i<reds.length; i++) {
    console.log( reds[i].name );
}
// Saab
// Peugeot
// Shimano

ObjectPath是一种类似于XPath或JSONPath的查询语言，但由于嵌入了算术计算、比较机制和内置函数，它的功能要强大得多。 请看语法:

商店里所有的鞋子都是红色的，价格在50美元以下

美元. .鞋子。*[颜色为“红色”，价格< 50]

我知道的其他选择是

JSONiq specification, which specifies two subtypes of languages: one that hides XML details and provides JS-like syntax, and one that enriches XQuery syntax with JSON constructors and such. Zorba implements JSONiq. Corona, which builds on top of MarkLogic provides a REST interface for storing, managing, and searching XML, JSON, Text and Binary content. MarkLogic 6 and later provide a similar REST interface as Corona out of the box. MarkLogic 8 and later support JSON natively in both their XQuery and Server-side JavaScript environment. You can apply XPath on it.

HTH.

Json指针似乎也得到了越来越多的支持。
