javascript - 如何使用变量作为字段键获取 Meteor 集合字段值

Question

我将给出一个代码示例来描述我的问题:

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 bracket notation 访问对象属性:

Collection.findOne(id)[someVariable];
