Email field and on screen keyboard

Hi,

I created an email field:

$("<input type='text' id='Email' name='Email' tabindex='1' maxlength='200' style='background-color:white; border:1px solid black' required>").appendTo(sym.$("emailbox")) .css({'font-size' : '200%', 'color':'blue'});

A submit button and a PHP-file that sends a message to the user´s email.

All this works.

I can write to the field with a physical keyboard.

But how would you append text with an on screen keyboard to the email field?

Would it be possible (when you press "a") with something like:

$("name or ID of text box").append("a");

I can´t get it working, probably because I´m targeting the wrong symbol?

Thanks!
