How can I disable all keyboard keys?

Question

I am searching for a possibility to disable all keyboard keys in a textarea. I found some examples on the web to disable some single ones but how can I disable the whole key

Assuming you have in textare the reference of your textarea, maybe something like:

textearea.onkeydown = textarea.onkeypress = function() { return false };

That it's probably an overkill, but... Considering to use the attribute readonly instead:

textarea.readOnly = true

In the first case you're still able to copy/paste using the mouse, in the second case you can only copy (using keys or mouse doesn't matter).
