This article mainly introduces the jQuery/Vue mouse movement in and out effect, which has certain reference value. Now I share it with you. Friends in need can refer to it

Implementation ideas

1. Position the direction of the element according to the position of the mouse
2. Dynamically set the mask layer style according to the direction
3. Set animation to move the mask layer

jQuery version

jQuery plug-in can be extended through the $.fn.extend method.

Vue version

General Vue component implementation determines the position of the mouse within an element. Use slots to display the contents of the mask layer.
