我的对象看起来像这样。如何重命名数组或对象中的每个键并使用 javascript 创建键值数组？

我的结果应该是这样的

compCode:0001

【问题讨论】：

请更加具体，并使用较小的数据集来显示您的问题。请参阅 How to Ask 和 minimal reproducible example。很难弄清楚你的问题是什么
您是在问如何展平对象吗？所以你的访问权限看起来像jsonObj["vndrAddr[1].vndrContact[0].contEmail"]
重命名什么键？我没有时间比较发生了什么变化。
你应该包含你到目前为止尝试过的代码。
如果你真的不知道他想做什么@shawon191，你怎么知道我的答案不会产生预期的输出？

【解决方案1】：

您可以通过使用括号保存数组索引的类型来采用迭代和递归方法。稍后将值分配给路径的新属性。

function setPath(object) {

    function iter(object, path, isArray) {
        Object.keys(object).forEach(function (key) {
            var temp = path + (isArray ? '[' + key + ']' : (path && '.') + key);
            if (object[key] && typeof object[key] === 'object') {
                return iter(object[key], temp, Array.isArray(object[key]));
            }
            result[temp] = object[key];
        });
    }

    var result = {};
    iter(object, '');
    return result;
}

var object = { a: { b: [{ c: { d: 'foo' } }, 'bar'] } };

console.log(setPath(object));
