Inject keyboard event to textarea
On HTML page I want to keep TEXTAREA controls read-only until the user starts typing characters. All other keyboard events should not change the read-only status. In my script, on the first typed character event the handler makes the control not read-only, but that character does not go to the control itself.
I tried to do the following:
I tried to do the following:
$(".textarea").keyup( function(ev) {
var k = ev.keyCode;
var inp = ev.target;
if( inp.readOnly && k >= 42 && k <= 90 ) { // an alphanumeric
inp.readOnly = false;
inp.select(); // without this IE do not accept typed in characters at all
// i tried this:
var sev = $.Event("keypress", {keyCode: k, which: k});
// and that:
var sev = $.Event("keypress", ev);
$(inp).trigger(sev);
}
} );

In any case, changing to keydown should do what you need, you won't have to inject anything.

I am implementing a spreadsheet-like data editing page. I searched for some existing implementations on the internet and those I found do not satisfy our needs. The user is supposed to be able to freely navigate through the grid of textarea elements with the arrow keys.

Thank you very much! The keydown handler works perfectly and I don't even need to inject the keypress event.
What is it you are trying to do?
Can you give us a context.

Just a bit confused as to why you have them as readonly, hence "unable to type into it", until they start typing into it?
