I would like to call a function which returns a boolean. How would I go about calling this function and storing the true or false in a variable? I have tried this var result = contract.checkCertHash(certid,hashedData,address); and initialised the contract using : var parsed= JSON.parse(fs.readFileSync(jsonFile)); const abi = parsed.abi; const contract = new web3.eth.Contract(abi, '0xce395e1f6532e128f35469bb304ca46660a9f376');

I tried searching over here but I have tried what I found but none worked. Thanks in advance!

  • What does your contract look like? I'm guessing your function is not view or pure so you can't get the return value directly. Nov 4, 2018 at 18:49

I found a way that works(Answering my own question): contract.methods.checkCertHash(certid,hashedData,address).call().then(function(result){}
