I am looking to simply copy and paste content into a textarea without needing to make any edits within the field.
<form action="save.php" method="post">
<h3>Text:</h3>
<textarea name="text" rows="4" cols="50"></textarea>
<br><br>
<input type="submit" name="submit" value="submit">
</form>To restrict key presses to only ctrl+c, ctrl+v, or ctrl+x, follow these steps:
Allowed keys:
ctrl+c, ctrl+v, ctrl+x, as well as the Copy and Paste buttons on RightClick.
Restricted keys:
Everything
$('textarea').on('keydown', function(e) {
var ctrl = e.ctrlKey ? e.ctrlKey : ((e.keyCode === 17) ? true : false);
if (e.keyCode === 86 && ctrl || e.keyCode === 67 && ctrl || e.keyCode === 88 && ctrl) {
return true;
} else {
return false;
}
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<textarea name="text" rows="4" cols="50">Some Text</textarea>Prevent editing in a textarea by disabling the keydown event and enabling the mousedown event. This way, users can only copy and paste without being able to make edits.
$(".area").bind("mousedown", function(e) {
console.log('hello')
});
$(".area").bind("keydown", function(e) {
console.log('world');
event.preventDefault();
});.touch {
pointer-events: none;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<h3>Text:</h3>
<textarea name="text" rows="4" cols="50" class="area"></textarea>
<br><br>
<input type="submit" name="submit" value="submit">To ensure that the keydown event is blocked on a textarea for all keyboard keypresses except for ctrl+c, ctrl+v, command+c, and command+v keys.
For Mac users, utilize event.metaKey to detect the command key.
Try copying text from the textarea using ctrl+c or pasting text inside it using ctrl+v

</form>Building upon Abhishek Singh's demonstration; in ES6 utilizing arrow functions and jQuery, it can be expressed concisely like this:
$textarea = jQuery("<textarea>")
.on("keypress", (e) => e.ctrlKey && e.key == "v")
(Similar scenario but using "c" to restrict anything other than copy)
