// 1) If enter is pressed:
// i) Prevent default operations - form submission.
// ii) close_timepicki().
// iii) return.
//
// 2) For any other key presses:
// i) realize that we cannot check what the user has typed
// just yet, because this function is a handler
// that runs before any text is rendered in the input
// box.
// ii) So, register a function validate() that will execute right
// after the keypress character is rendered. All validation
// is done inside validate().
//-----------------------------------------------------------------------------------
// NOTE:.change() event does not work here, as it is called when input looses focus|
