You need to be more clear and show us where you are stuck. But you probably want to use the keypress event. http://www.w3schools.com/jsref/event_onkeypress.asp

If you mean mouse cursor, nothing can prevent moving it.
If you mean text input caret, you don't want to prevent its motion, because it's used to fill in the text input control.
So, the question, as formulated, makes no sense.

If you mean to capture shifting of the keyboard focus, you can do it by handling some of the focus-related events: blur, change, focus, focusin, focusout:

Sorry, I cannot understand what you say.

You can use the focus event to capture when the focus is going from the control being validated to some other control. In your handler, you can perform validation and show some indication if the control data/state is invalid.

Franky, I would not go that far. Most general way is to validate all controls on some page or, say, panel, when you are about to use the entered data, say, when you click something like a "Submit" button. But, if you want, you can validate separate controls.
