二.效果展示

使用步骤如下：

①设置两位选手的姓名：

②然后就可以根据两位选手的比赛情况，进行分数设置。

比分制度采用14710制。

即：犯规=减1分、普胜=4分、小金=7分、大金=10分、黄金九=4分。

点击两位选手的不同按钮，进行加分、减分。

三.该计分器的优点

        优点如下：

        ①采用水上、水下制，即：两个选手的分数之和永远为0。这样一眼就能看出来谁水上、水下多少分。

        举例：上图中，选手【秦利文】分数为6，代表水上6分；选手【617】分数为-6，代表水下6分。

        ②两位选手的每种球形（如：普胜、大金、小金等）数量都可以记录下来，方便比赛结束后复盘自己的发挥情况，从而后期针对性弥补自己的缺点。

③该计分器界面美观，比赛结束后可以截图分享朋友圈。

④可以在手机浏览器运行该html文件，横屏运行的界面也十分美观。如下：
