前言

关于【生命游戏】之前小编写发过一篇Java版的,这里就不再对其介绍了,不了解的读者可以点下方链接前往了解:
https://blog.csdn.net/weixin_44155115/article/details/103884572

这一次小编做了一个web版的,并分享在我的码云上,感觉用js做确实是比Java的swing做起来方便很多,这也算是小编初学前端第一个练习吧。

效果图

先看看效果图吧!

在这里插入图片描述

源码

这里小编把源码附上,送给和我一样初学前端的朋友,也希望路过的大佬不吝赐教,哈哈。

				<h2>游戏简介</h2>
				<p>生命游戏(game of life)为1970年由英国数学家J. H. Conway所提出
					某细胞的邻居包括上、下、左、右、左上、左下、右上与右下相邻之细胞 游戏规则如下:</p>
				<p><b>孤单死亡:</b>如果细胞的邻居小于等于1个,则该细胞在下一次状态将死亡;</p>
				<p><b>拥挤死亡:</b>如果细胞的邻居在4个及以上,则该细胞在下一次状态将死亡;</p>
				<p><b>稳定:</b>如果细胞的邻居为2个或3个,则下一次状态为稳定存活;</p>
				<p><b>复活:</b>如果某位置原无细胞存活,而该位置的邻居为2个或3个,则该位置将复活一个细胞。</p>
