When you are using a form tag, u need to be careful to the buttons, cause by default in a form they are type="submit", and this cause the page to refresh every time they are clicked.

To fix the problem just specify the button type like so:
```
<button type="button" id="requestbtn">Request Access</button>
```
Hope it helps 🙂

The button missing the type attribute won’t know to submit the form when button is clicked.

<button type="submit" id="requestbtn">Request Access</button>

To account for button pressed or user pressing enter on the email field, suggestion to add event listener to form.
To prevent form submission on error, use event.preventDefault()

const requestAccessForm = document.getElementById("requestAccessForm");
let requestBtn = document.getElementById("requestbtn");
let oops = document.querySelector(".oops")


requestAccessForm.addEventListener("submit", (event) => {
  let emailInput = document.getElementById("email");
  
  if (emailInput.value === "") {
    oops.classList.remove("hidden");
    
    console.log("invalid email");
    // Will prevent form from submitting
    event.preventDefault();
    
  } else {
    // else statement just for testing
    console.log("form will submit");
  }
});

const requestAccessForm = document.getElementById("requestAccessForm");
let requestBtn = document.getElementById("requestbtn");
let oops = document.querySelector(".oops")


requestAccessForm.addEventListener("submit", (event) => {
  let emailInput = document.getElementById("email");
  
  if (emailInput.value === "") {
    oops.classList.remove("hidden");
    
    console.log("invalid email");
    // Will prevent form from submitting
    event.preventDefault();
    
  } else {
    // else statement just for testing
    console.log("form will submit");
  }
});

As Edoardo Balducci mentions, buttons are type="submit" by default. This means, clicking the button will try to submit its associated form.

Since the input field is not required, it is optional. Because it is the form’s only form control, the form is always valid and will always submit when requested (here: clicking the button).

To prevent submission, try (one of) the following:
- Make the input field required.
- Conditionally prevent the click from submitting the form (by calling event.preventDefault()).
- Change the button to type="button", and conditionally submit the form manually (e.g. by calling form.requestSubmit())
As Arty.Simon mentions, it would be better to listen to a submit event on the form. This better conveys intent and also handles form submission requests originating from elsewhere than the button.
