how can i make a textfield that only accepts letters backspace and spacebar only
<p>i need to have a textfield that does not show anything if the user typed special characters or numbers. i have this Name textfield and i need to narrow it to letters input only. the user can also backspace and shift (by using keypress or keytyped or keyrelease whichever be better) </p>
