======================================================= ===============
When the mouse enters the blue square, an 'OK' prompt is displayed, which is normal.
When the mouse enters the green square, an "OK" prompt appears, how can I not prompt
When the mouse enters the blue square from the green square, the "OK" prompt appears again. This prompt also wants to be removed.
Purpose: Only when the mouse enters the blue square, a prompt appears. Do not show a prompt on how to move inside the blue square. . . |
