如何根据对象内的某些匹配项插入特定值

Question

I have two objects with the following structure:

var one = { 
    '26-34-1'  : 100,
    '26-34-84' : 101
};

var two = [ 
    { 
        from : { id: '34', sid: '26' },
        to   : { id: '1',  sid: '26' } 
    },
    { 
        from : { id: '34', sid: '26' },
        to   : { id: '84', sid: '26' } 
    }
];

The keys in one (eg. 26-34-1) identify an object in two in the format:
from.sid - from.id - to.id

What I need to do is insert the value from one into two if the key in one matches. Resulting in:

var two = [ 
    { 
        from  : { id: '34', sid: '26' },
        to    : { id: '1',  sid: '26' },
        oneid : { id: 100 }
    },
    { 
        from  : { id: '34', sid: '26' },
        to    : { id: '84', sid: '26' },
        oneid : { id: 101 } 
    }
];

I can't seem to figure it out, I think it's done with "mapping" but wasn't able to map from.sid , from.id and to.id . Can someone please shed some light on this?

Answer 1

Edit : As I understand from another answer it's not what TS was asking about, my in case he doesn't have two yet next code will do what's needed.

for (var key in one) {
  var values = key.split('-');
  var object = {
    from: {
      id: values[1],
      sid: values[0]
    },
    to: {
      id: values[2],
      sid: values[0]
    },
    oneid: {
      id: one[key]
    }
  };

  two.push(object);
}

Answer 2

two.forEach(function(o){
    var key = [o.from.sid, o.from.id, o.to.id].join('-');
    if(key in one) o.oneid = { id: one[key] };
});

• Javascript in operator
• Array.prototype.forEach
• Polyfill (for old browsers)
