将变量添加到对象文字

Question

I'm trying to add a variable to an object I'm creating, but when I log the object id appears simply as id , instead of my ref.key() value.

var id = ref.key();

var newItem = {
  'provider1': {
    'services': {
      id: true
    }
  }
};

console.log(newItem);

Any idea what I'm doing wrong? Any help is appreciated. Thanks in advance!

Answer 1

You should use bracket notation:

var id = ref.key();

var newItem = {
  'provider1': {
    'services': {}
  }
};
newItem.provider1.services[id] = true;

console.log(newItem);

Answer 2

var id = ref.key();

and

'services': {
      id: true
    }

Have absolutely nothing to do with each other. One is a variable while the other is an object key name that you are setting to true .

'services': {
      id: id // <-- this id has your ref.key() value
    }

Would make more sense.
