I wrote a code which can connect to a contract and reads its total supply. here is my code(I removed abi because it was too big and didnt copy it here):
const Web3 = require('web3')
const rpcURL = "https://bsc-dataseed1.binance.org:443"
const web3 = new Web3(rpcURL)
const abi = []
const c_address = "0xA964a6dab034A4b5985603f7e86a596c7e0eA96e"
const contract = new web3.eth.Contract(abi, c_address)
contract.methods.totalSupply().call((err, result) => { console.log( web3.utils.fromWei(result, 'ether')) })
I watched some tutorials to write this and the last line confuses me. how can I change the last part to make it display the total supply using document.write? I actually need to use this on a html page. can anyone help me? my javascript knowledge is very limited. thanks
Best Answer
you can place your javascript logic inside the fat arrow function.
For example:
If you are using pure html and js then I would suggest using
document.getElementById()
instead ofdocument.write()
because the latter replaces the entire html page. Take a look on how to do that here You can also find tutorials on how to write on specific document elements here
