Height: window height Dir: Specifies the image scroll direction. By default, the image scroll to the left. Speed: the scrolling speed. The smaller the value, the faster it is. EventBingLeft: ID of the scroll button to the left EventBingRight: ID of the scroll button to the right Other Instructions: Currently, this plug-in only supports seamless scrolling between the left and right due to time reasons. This is also the first time that the author tries to encapsulate the plug-in,
If the plug-in cannot be normally referenced, please notify the author via QQ or email, or you can fix it yourself This plug-in code can be copied and released at will, but cannot be used for commercial purposes. Please keep this plug-in information when reprinting. Thank you.
