import wixLocation from 'wix-location';
import wixUsers from 'wix-users';
import wixData from 'wix-data'

$w.onReady(function () {

//check the current user's email using getEmail()
let user = wixUsers.currentUser;

user.getEmail()
  .then( (email) => {
 let userEmail = email;      // "user@something.com"
  } );

//autofill the email into the dataset
$w("#input3").value = userEmail;

//query the mylist dataset
wixData.query("mylist")
  .eq("email")
  .find()
  .then( (results) => {
 
 //if the dataset does NOT have the email, then make the inputs fields blank since this is their first time submitting
 if(userEmail NOT "email"){
        $w('#input1').value = undefined
        $w('#input2').value = undefined
        $w('#input3').value = undefined
        $w('#input4').value = undefined

        $w('#input6').value = undefined
    }
  } )
  .catch( (err) => {
 let errorMsg = err;
