Anyone that can help me in how to interact with our smartcontract using web3.js.

I tried below code but this not work: This the code that I am using:

if (typeof web3 !== 'undefined')
  web3 = new Web3(web3.currentProvider);} 
else {
                web3 = new Web3(new Web3.providers.HttpProvider("htpp://localhost:8545"));

            web3.eth.defaultAccount = web3.eth.accounts[0];

            var careercertificateContract = web3.eth.contract(CODE ABI);

        var careercertificate = careercertificateContract.at('0xe1EeCd0a848Bf59509F32f0c97B61d34727C84AB');


            Certificate.createCertificate($("#id").val(), $("#fecha").val(), $("#NombreAlumno").val(), $("#RutA").val(), $("#NombreInstitucion").val(), $("#RutI").val(), $("#titulo").val(), $("#FechaTitulacion").val(), $("#NumeroRegistro").val(), $("#CodigoVer").val(), $("#TotalHash").val(),);


Use careercertificate.createCertificate(params) instead of Certificate.createCertificate(params) because careercertificate is the instance that is properly pointing to the contract. And if using web3js@0.20 then defiantly use callback functions for the response e.g

 careercertificate.createCertificate(params, (err, res) => { //es6 
    if(!err) //some logic

OR If using web3js1.0.0 then using async/await or then e.g

careercertificate.createCertificate(params).then(res => {
   //some logic

Hope it helps!
