Simulate enter on textarea with jquery event keydown not working

Question

I was trying to make facebook autoreply msg script, here is my code

$(window).load(function(){
var a=setInterval(function(){
var e = $('.titlebarText').html();
if(!e)
{
}
else
{
$('textarea.uiTextareaAutogrow.input').focus().val('Test!');
var c = jQuery.Event("keydown");
c.which = 13; 
$('textarea.uiTextareaAutogrow.input').trigger(c);
}
}
,5000);
});


$(window).load(function(){
var q=setInterval(function(){
$('.close').click()}
,6000);
});

Everything is working perfectly but simulating enter after focusing on textarea and inserting value..

Not sure what you're trying to do. Simulating user input is bad and unnecessary generally. What's your expected result? Do you want to insert a line break or submit it automatically? — Fabrício Matté, Jul 08 '12 at 04:33
Is the textarea in a form? If so you could submit that form: `$('textarea.uiTextareaAutogrow.input').closest('form').submit();` — nnnnnn, Jul 08 '12 at 04:36
@FabrícioMatté submit it automatically, just like writing on chat. But i tested now and it wont trigger anyting, not just enter.. Don't know how to fix that.. — Velja Janković, Jul 08 '12 at 04:36
+1 @nnnnnn, [`.submit()`](http://api.jquery.com/submit/) is the way to go. (I'm checking if there's any form to be submitted in the facebook api) — Fabrício Matté, Jul 08 '12 at 04:38
@nnnnnn nice one, but it's submiting form which is posting on wall, and it's working, but not on chat.. — Velja Janković, Jul 08 '12 at 04:39
Try with `textarea.uiTextareaAutogrow.MessagingComposerBody` for the chat (or just take out the `.input` class from the selector) — Fabrício Matté, Jul 08 '12 at 04:43
@FabrícioMatté without .input it's sending me to https://www.facebook.com/ajax/ufi/modify.php and first one is not working at all. looks like there is no form for chat, maybe — Velja Janković, Jul 08 '12 at 04:47
Yeah, I posted that after inspecting FB's markup. It's really messy to find anything useful, at this rate you'll most likely have to call the function which submits the chat message. — Fabrício Matté, Jul 08 '12 at 04:51

Your selector looks strange. textarea.uiTextareaAutogrow.input says "the textarea with class uiTextareaAutogrow and class input"--do you really have a textarea tag with the class input?

You could try this, provided your selector is correct:

var e = $.Event('keydown', { keyCode: 13 });
$('textarea.uiTextareaAutogrow.input').trigger(e);
