Three buttons waiting for a user to click one of them.
Figure 13.17
The user clicked the Night button.
The
onFocus
event handler is triggered when a form element has focus: The cursor is sit-
ting in the box, waiting for key input or in the case of a button, for the Enter key to be
pressed. The
onBlur
event is triggered when the form element loses focus, when the cur-
sor is moved away from the input device.
