The onkeypress attribute can be set on input elements of type "text", or "select" when editable is true, to run a specific action when a key is pressed in the field. This is commonly used in combination withe onchange to limit the contents of the field to a specific value - digits only, for example.
The input field is limited to digits only. This is done using two JavaScript methods that are built in to Acrobat
<input type="text" name="amount" onKeyPress="javascript:AFNumber_Keystroke(2,1,1,0,'',true)"/>
