JavaScript中的字符串到对象，一个对象[关闭]

Question

我有一个字符串

string = "foo.call=45&doo.foo=20&foo.in=5";

现在我需要一个对象 obj 这样

obj = {"foo": {"call": "45"}} {"foo": {"call": "45","in":"5"},"doo": {"foo":20}}

如何在 JavaScript 中做到这一点？ 对于一个字符串 = "foo.call=45"

function aaa(string){
    var aa = string.split('=')[0],
        bb = string.split('=')[1];
    function setValue(object, path, value) {
    var way = path.split('.'),
        last = way.pop();
    way.reduce((o, k) => o[k] = o[k] || {}, object)[last] = value;
    return object;
    }
    var object = JSON.stringify(setValue({}, aa, bb));
    console.log(object);    
}

Answer 1

你可以用等号分割字符串，并将左边的部分作为对象中值的路径。

function setValue(object, path, value) {
    var way = path.split('.'),
        last = way.pop();

    way.reduce((o, k) => o[k] = o[k] || {}, object)[last] = value;
    return object;
}

function getObject(string, object = {}) {
    string
        .split('&')
        .forEach(s => setValue(object, ...s.split('=')));

    return object;
}

console.log(getObject('foo.test.rest.call=45'));
console.log(getObject('foo.call=45&doo.foo=20&foo.in=5'));
