javascript - 获取JSON对象的子项名称

我需要获取json的xpath（即，基本上），我需要获取json的密钥及其xpath。

var json='"glossary": {
    "title": "example glossary",
    "GlossDiv": {
        "title": "S",
        "GlossList": {
            "GlossEntry": {
                "ID": "SGML",
                "SortAs": "SGML",
                "GlossTerm": "Standard Generalized Markup Language",
                "Acronym": "SGML",
                "Abbrev": "ISO 8879:1986",
                "GlossDef": {
                    "para": "A meta-markup language, used to create markup languages such as DocBook.",
                    "GlossSeeAlso": ["GML",
                    "XML"]
                },
                "GlossSee": "markup"
            }
        }
    }
}

Object.keys(json)

上面的代码返回父结构的键，如下所示。

[ 'glossary' ]

我需要所有键以及路径，我被困在这里，任何解决方案都将非常有帮助

最佳答案

也许这就是您想要的：

var json={"glossary": {
    "title": "example glossary",
    "GlossDiv": {
        "title": "S",
        "GlossList": {
            "GlossEntry": {
                "ID": "SGML",
                "SortAs": "SGML",
                "GlossTerm": "Standard Generalized Markup Language",
                "Acronym": "SGML",
                "Abbrev": "ISO 8879:1986",
                "GlossDef": {
                    "para": "A meta-markup language, used to create markup languages such as DocBook.",
                    "GlossSeeAlso": ["GML",
                    "XML"]
                },
                "GlossSee": "markup"
            }
        }
    }
}};

function getKeys(keys, obj, path) {
    for(key in obj) {
        var currpath = path+'/'+key;
        keys.push([key, currpath]);
        if(typeof(obj[key]) == 'object' && !(obj[key] instanceof Array))
            getKeys(keys, obj[key], currpath);
    }
}

var keys = [];
getKeys(keys, json, '');
for(var i=0; i<keys.length; i++)
    console.log(keys[i][0] + '=' + keys[i][1]);

结果是：

词汇表= /词汇表

标题= /词汇表/标题

GlossDiv = /词汇表/ GlossDiv

标题= /词汇表/ GlossDiv /标题

GlossList = /词汇表/ GlossDiv / GlossList

GlossEntry = /词汇表/ GlossDiv / GlossList / GlossEntry

ID = /词汇表/ GlossDiv / GlossList / GlossEntry / ID

SortAs = /词汇表/ GlossDiv / GlossList / GlossEntry / SortAs
