title: How to interact with my smart contract on web browser
body: <p>I deployed my contract on ropsten.<br />
  And I tried to interact with it on browser but error message said that it is not a function.<br />
  I already tried at NodeJS and there was no error. So the contract address or ABI file isn't wrong.</p>
  <p>This is my code. Is there an error here?</p>
  <pre><code>const address = 'Contract addresss';
  const myContract = new web3.eth.Contract(ABI, address);
  let result = await myContract.methods.createDoc('asdf').call();
  console.log(result);
  </code></pre>
