Web3js – How to Parse Web3 Returned JSON Objects of Events?

javascriptjson-rpcweb3jsweb3js-v1.x

I am using Web3 1.0 to listen to events from a contract like this:

tokenContract.events.AddressList({
        fromBlock: 6020474,
        toBlock: 'latest'
    },
    (error, events) => { 
        console.log(events.returnValues[0])
     }
);

I get back this:

      {

        transactionIndex: 12,
        id: 'log_0x18cb49c233bb0591f3b16eaa31c573a0171ce9d96390bd0639d741664d19f043',
        returnValues: {
          '0': '0xd204E0f9c07768D91eA2f27Dc01d48DC485e5046',
          '1': '0x6a57059920371e6819713c80a2c3E3E4fE21b7A6',
          '2': [BigNumber],
          src: '0xd204E0f9c07768D91eA2f27Dc01d48DC485e5046',
          guy: '0x6a57059920371e6819713c80a2c3E3E4fE21b7A6',
          wad: [BigNumber]
        },
        event: 'Approval',

      }
    ]
    [
      {

        transactionIndex: 13,
        id: 'log_0xff56909901d0d7f2981eb2b51383a5f284dc9ffa3626876cc5a62c84dedf821b',
        returnValues: {
          '0': '0xE59B0539f3eC6a8b70D60fEf5FcEDFB2C07516F4',
          '1': '0x6a57059920371e6819713c80a2c3E3E4fE21b7A6',
          '2': [BigNumber],
          src: '0xE59B0539f3eC6a8b70D60fEf5FcEDFB2C07516F4',
          guy: '0x6a57059920371e6819713c80a2c3E3E4fE21b7A6',
          wad: [BigNumber]
        },
        event: 'Approval',

        }
      }

I want to push each returned events.returnValues[0] property (which is the field name '0:') to an
array like this: 

var addresses = [] 
    addresses = events.returnValues[0]
    addresses = objArray.map(events => a.returnValues)

//(Or maybe by iterating with a for loop somehow)

Then I want to access the individual addresses with something like
console.log(addresses[2])

Is there a better way to do this with Web3.js alone? All of the answers parsing JSON have not worked for me. I don't know where to begin.

Edit: It appears that Web3 returns not a JSON object containing all events, but individual objects. For example, Object.keys(AddressList).length returns:

1
1
1
1
1

And console.log(events.returnValues['0']) returns:

0xd204E0f9c07768D91eA2f27Dc01d48DC485e5046
0xd204E0f9c07768D91eA2f27Dc01d48DC485e5046
0xd204E0f9c07768D91eA2f27Dc01d48DC485e5046
0xd204E0f9c07768D91eA2f27Dc01d48DC485e5046
0xE59B0539f3eC6a8b70D60fEf5FcEDFB2C07516F4

The best I've got so far was this:

[ '0xd204E0f9c07768D91eA2f27Dc01d48DC485e5046' ]
[ '0xd204E0f9c07768D91eA2f27Dc01d48DC485e5046' ]
[ '0xd204E0f9c07768D91eA2f27Dc01d48DC485e5046' ]
[ '0xd204E0f9c07768D91eA2f27Dc01d48DC485e5046' ]
[ '0xE59B0539f3eC6a8b70D60fEf5FcEDFB2C07516F4' ]

Which gets pushed only to the first entry of the array altogether. I want addresses[4] to return the address ending in 16F4, and addresses itself to return:

['0xd204E0f9c07768D91eA2f27Dc01d48DC485e5046', '0xd204E0f9c07768D91eA2f27Dc01d48DC485e5046', '0xd204E0f9c07768D91eA2f27Dc01d48DC485e5046', '0xd204E0f9c07768D91eA2f27Dc01d48DC485e5046', 0xE59B0539f3eC6a8b70D60fEf5FcEDFB2C07516F4]

Edit two. The following code results in a wonky and unexpected return:

let myArr = []
tokenContract.events.AddressList({
        fromBlock: 6020474,
        toBlock: 'latest'
    },
    (error, events) => { 
        myArr.push(events.returnValues['0'])
     }
);

[ '0xd204E0f9c07768D91eA2f27Dc01d48DC485e5046' ]
[
  '0xd204E0f9c07768D91eA2f27Dc01d48DC485e5046',

Best Answer

Try with this events.returnValues['0'].

Or did you try something like this:

let myArr = []
tokenContract.events.AddressList({
        fromBlock: 6020474,
        toBlock: 'latest'
    },
    (error, events) => { 
        myArr.push(events.returnValues['0'])
     }
);

Or did you try this tokenContract.events.getPastEvents(event[, options][, callback])
