How do I compare user input to a variable?

BEARDYN DUBAY

I don't know how to make this work. Does anyone know how to fix this? I have tried multiple different solutions, but they don't work

function submit() {
  var user = "test";
  if (document.getElementById('#user').input = user) {
    //what I need help on
  }
}
function openForm() {
  document.getElementById("myForm").style.display = "block";
}

function closeForm() {
  document.getElementById("myForm").style.display = "none";
}

<button class="open-button" onclick="openForm()">Open Form</button>

<div class="form-popup" id="myForm">
  <form action="#" class="form-container">
    <h1>Login</h1>

    <label for="username"><b>username</b></label>
    <input type="text" placeholder="username" id="username" name="username" required>
    <button type="submit" onclick="submit()" class="btn">Login</button>
    // And here
    <button type="button" class="btn cancel" onclick="closeForm()">Close</button>
  </form>
</div>

First, where is user input element, that you mentioned in JavaScript, there is no input with id user, only one input with id username exist, use that and hashtag is not used for ids in document.getElementById replace

document.getElementById('#user')

document.getElementById('username') // use username and remove the hashtag (#)

Secondly, use value instead of input

document.getElementById('username').value

Returns the value (text) of the input element

Lastly, use == or === operators in statements not = in JavaScript.

Example

if (document.getElementById('username').value === user) { // Replaced = with ===
    //what I need help on
}

Full JavaScript Code

function submit() {
  var user = "test";
  if (document.getElementById('username').value === user) {
    //what I need help on
  }
}
function openForm() {
  document.getElementById("myForm").style.display = "block";
}

function closeForm() {
  document.getElementById("myForm").style.display = "none";
}
