A simple sample for retrieving the contractABI using Web3.js and Jquery to interact with a contract

    var Web3 = require('web3');
    var web3 = new Web3(new Web3.providers.HttpProvider());
    var version = web3.version.api;
            
    $.getJSON('http://api.etherscan.io/api?module=contract&action=getabi&address=0xfb6916095ca1df60bb79ce92ce3ea74c37c5d359', function (data) {
        var contractABI = "";
        contractABI = JSON.parse(data.result);
        if (contractABI != ''){
            var MyContract = web3.eth.contract(contractABI);
            var myContractInstance = MyContract.at("0xfb6916095ca1df60bb79ce92ce3ea74c37c5d359");
            var result = myContractInstance.memberId("0xfe8ad7dd2f564a877cc23feea6c0a9cc2e783715");
            console.log("result1 : " + result);            
            var result = myContractInstance.members(1);
            console.log("result2 : " + result);
        } else {
            console.log("Error" );
        }            
    });
