Parsing Hash Args for Cognito Auth – Javascript

Hi everyone,

A quick post on a function for parsing hash args when using AWS Congito.

//jsfiddle.net/4eo7836j/embed/

Just in case the fiddle ever disappears:

const parseHashArgs = aURL => {

  aURL = aURL || window.location.href;

  var vars = {};
  var hashes = aURL.slice(aURL.indexOf('#') + 1).split('&');

  for (var i = 0; i  1) {
      vars[hash[0]] = hash[1];
    } else {
      vars[hash[0]] = null;
    }
  }

  return vars;
};

document.body.append(parseHashArgs("#id_token=testtokenval&token_type=bearer&expires_in=3600")["id_token"]);
