How to get values from multiple form field values using Array.from and forEach

Question

Lets say I have a form:

<form>
  <input type="text" class="blanked">
  <input type="text" class="blanked">
  <input type="text" class="blanked">
  <input type="submit" value="Press Me">
</form>

Now lets say I use getElementsByClassName to create an array of these elements:

let filledBlanks = Array.from(document.getElementsByClassName( 'blanked' ));

Now I want to iterate through the values the user has entered into each input:

filledBlanks.forEach( filledBlank => {
  let inputText = filledBlank.???;
}

This is where I get tripped up. What do I use to get the filled value (not .value)? Or is there a better way to accomplish this?

"What do I use to get the filled value (not .value)" Why? — adiga

Thanks everyone for the feedback. .value wasn't working for me initially, which is why I said not .value above...but after hearing that it should work I went back and realized my JS was running when the page initially loaded and not with the onclock event thus why value had been returning empty values for me previously. — Dave Mackey

the .value property works just fine. I don't see why you would need something else. If you want to only iterate over the values, you could map your input first, but i don't see the point.

Please note here that i'm only using Jquery to listen to the submit event. The rest is pure vanilla Javascript.

$('form').on('submit', (event) => {
  event.preventDefault();
  
  let filledBlanks = Array.from(document.getElementsByClassName( 'blanked' ));
  filledBlanks.map((input) => {
    return input.value;
  }).forEach((value) => {
    console.log(value);
  });
  
});

<form>
  <input type="text" class="blanked">
  <input type="text" class="blanked">
  <input type="text" class="blanked">
  <input type="submit" value="Press Me" id="submit">
</form>

Thanks Nicolas. As I mention in the comments above, the issue was elsewhere in my code. I had the JS outside of a function and it was running on page load rather than after the submit button had been click, so it was always returning empty...thus why I thought value didn't work.
