How to get Meteor collection field value using variable as field key

Question

I'll give a code example to describe my problem:

var id = Collection.insert({
    name: 'Charles Darwin',
    likes: 1
});

var someVariable = 'name';

Collection.findOne(id).name // This returns 'Charles Darwin', but how do I use someVariable to get the same result?
Collection.findOne(id).someVariable // This will certainly not work, but what is the right way to do it?

Answer 1

尝试使用方括号表示法访问object属性：

Collection.findOne(id)[someVariable];
