I have used web3.eth.abi.decodeParameters and returned values have been pushed into my array (finalGettersParams.push(...)) something like this.

   [ Result { __length__: 0 },
  Result {
    '0': '0x0000000000000000000000000000000000000000',
    __length__: 1 },
  Result {
    '0': '0x0000000000000000000000000000000000000000',
    '1': '0x0000000000000000000000000000000000000000',
    __length__: 2 } 
    ]

Now i want to access individual elements of "Result"from my array. I can access finalGettersParams[2].__length__ and its print 2. However, i am not sure how to access the '0' and '1' .... like this finalGettersParams[2].'0' These 0, 1 are dynamic.. means they can be increased 0, 1, 2, 3 or decreased (depending on my arguments list, you can see in above array)

This is a general Javascript question (not specifically related to Ethereum).

Instead of this:

inalGettersParams[2].'0'

Use this:

inalGettersParams[2]['0']

  • @AmirAli: You're welcome, no need to apologize for anything here (I just wanted to emphasize that the problem was not Ethereum-related). Dec 18, 2019 at 7:01
  • Thanks again...... one more question, I am not sure should I make another question or in this comment will be OK ? Because it's a extension of this question ... is it possible to give all parameters ('0', '1', ...) of above mentioned finalGettersParams array to my myContractInstance.methods[myFunc](...finalGettersParams[j]).call({from: account1})... f

  • @AmirAli: What's your function's prototype? Dec 18, 2019 at 7:24
  • i think, now it does't matter... because now i have function name/methodID and their parameters (in above forms) ... can i use this information to call getters without knowing its prototype.. ?
