javascript - 使用 lodash 的特定对象属性值

Question

我有一个对象:

{
    "x" : "a",
    "y" : "b",    
    "z" : "c",    
}

我有一个数组:['x', 'y']。我如何从上面的对象中得到结果:

{
    "x" : "a",
    "y" : "b"
}

Answer 1

您可以使用 _.pick

var data = {
    "x" : "a",
    "y" : "b",    
    "z" : "c",    
};

console.log(_.pick(data, ['x', 'y']));
console.log(_.pick(data, 'x', 'y'));
