对象的key值变量替换

// 原数据

var data = {

id: '1',

name: '张三'

}

// 要改变的数据

var keyMap = {

'id': '序列',

'name': '姓名'

}

 

function transformKey(data, keyMap) {

let newObj = Object.keys(data).reduce((newData, key) => {

let newKey = keyMap[key] || key;

newData[newKey] = data[key];

return newData;

}, {});

return newObj;

}

transformKey(data, keyMap);
