在浏览器或chrome扩展程序中确认交易之前如何获取web3合约地址？

Question

Let's say I want to buy an NFT and my Metamask popup opens asking me to confirm the transaction. There you can see the contract address... but how can I access this contract address (just retrieve the value, not change it :) ) programmatically using javascript in the browser or an extension?

Hey for getting the contract address on your console just include this code in the .sol file and also update the abi of the code .

    function get() view public returns(address ){
        return address(this);
    }

And in the frontend to intract with your smart contract and for getting the result in the console include this in your index.js file

              contract.methods.get().call().then(function (resp){
               console.log(resp);
              });
