从JSON对象动态删除属性

Question

我必须从JSON对象中删除属性。 就像我需要编写一个框架，在其中传递需要从中删除字段的位置数组。 我的JSON请求如下所示

{
"name": "Rohit",
"other": [{
    "tfn": "2879872934"
}, {
    "tfn": "3545345345"
}],
"other1": {
    "tfn": "3545345345"
},
"other2": {
    "other3": [{
        "tf2n": "2879872934"
    }, {
        "tfn": "3545345345"
    }, {
        "tfn": "2342342234"
    }]
},
"card": "sdlkjl",
"tfn": "2879872934",
"f": true}

如上所述，这就是我捕获需要删除的位置的方式

let paths = ['other.tfn','tfn','other1.tfn','other2.other3.tfn'];

它从几乎所有位置删除tfn字段并返回

{
"name": "Rohit",
"other": [
    {},
    {}
],
"other1": {},
"other2": {
    "other3": [
        {
            "tf2n": "2879872934"
        },
        {},
        {}
    ]
},
"card": "sdlkjl",
"f": true}

我很好奇是否有人可以建议一种更好的方式来编写下面的代码

paths.forEach(function (path) {
           let keys = path.split('.');
           deepObjectRemove(jsonObject, keys);
        });

方法

var deepObjectRemove = function(obj, path_to_key){
if(path_to_key.length === 1){
    delete obj[path_to_key[0]];
    return true;
}else{
    if(obj[path_to_key[0]] && Array.isArray(obj[path_to_key[0]])) {
        obj[path_to_key[0]].forEach(function (value) {
            deepObjectRemove(value, path_to_key.slice(1));
        });
        //return deepObjectRemove(obj[path_to_key[0]], path_to_key.slice(1));
    }else if(obj[path_to_key[0]]){
        deepObjectRemove(obj[path_to_key[0]], path_to_key.slice(1));
    }else{
        return false;
    }
}};

Answer 1

 function deepObjectRemove(object, path) { const parts = path.split("."); let current; while (current = parts.shift()) { if (!object) { return; } const item = object[current]; if (item !== undefined) { if (!parts.length) { delete object[current]; } if (item instanceof Array) { return item.forEach((item) => deepObjectRemove(item, parts.join("."))); } } object = item; } } const object = { a: { b: { c: "1", d: 0 } }, b: [ { a: { b: "0", c: "1" } }, { a: { b: "0", c: "1" } } ] }; console.log("before", object); [ "abc", "bac" ].forEach((path) => deepObjectRemove(object, path)); console.log("after", object);
