Enable text area by clicking a button and not printing it at the same time

wish helps you Use Event.preventDefault() to prevent the letter from appearing in the text area. However, you'll have to neutralize the event listener afterwards, if you want the user to be able to type the letter i.
code :
const focus = document.getElementById('focus');

document.addEventListener('keydown', function eventListener(event) {
  if (event.keyCode !== 73) {
    return;
  }
  
  focus.disabled = false;
  focus.focus();

  event.preventDefault(); // prevent the default behavior

  document.removeEventListener('keydown', eventListener); // remove the event listener
});
<textarea id="focus" disabled></textarea>

wish of those help Well, you should somehow store if the button is clicked and if yes on what date/time. Or only just keep the date and time and if it's empty (only the first time) it hasn't been pressed yet, and else just check if it was more or less than a day ago.
You could store this value in a text file of a database.
code :
<?
if ($dateLastPressed < $aDayAgo)
{
   echo '<input type="submit" class="myButton" id="option" value="submit" disabled = "disabled"/>';
}
else
{
   echo '<input type="submit" class="myButton" id="option" value="submit"/>';
}

fixed the issue. Will look into that further FYI, ajax is not for validation. Its for asynchronous fetching of data from the server.
code :
if (document.getElementById('welcome').checked) {
    var textarea = document.getElementById('comment');

    if (textarea.value = '') {
        // validation failed
        return false;
    } else {
        return true;
    }
}

may help you . The state of JavaFX controls is represented by observable properties. So the RadioButton has a selectedProperty and the TextArea has a editableProperty. You can set and retrieve the values of these with the usual set/get (or set/is) methods: txtareaMessage.setEditable(rbYes.isSelected()), you can also observe them for changes:
code :
rbYes.selectedProperty().addListener(...);
txtareaMessage.editableProperty().bind(rbYes.selectedProperty());

seems to work fine You need to get the value of textarea when the button is clicked so assign the message variable inside the event listener. Because we want to get the value of textarea each time button is clicked.
code :
var button = document.getElementById('btn');
button.addEventListener('click', function() {
    var message = $('textarea#message_box').val();
    console.log(message)
});

To fix this issue One possibility is to add a property to your 'item' object and name it 'edit'. By default you could set this property to 'false'.
code :
editAnswer(item) {
  item.edit=true;
}
<td>
   <textarea *ngIf=item.edit"></textarea>
   <span *ngIf="!item.edit">--</span>
</td>
