大家有没有发现,好像很多网站都有点击屏幕显示一个五颜六色的爱心/爆炸球的特效?

下面我来介绍一下实现的方法。其实很简单,只有两行代码:
<canvas class="fireworks" style="position:fixed;left:0;top:0;z-index:99999999;pointer-events:none;"></canvas> <script type="text/javascript" src="调用的javascript脚本路径"></script>
爱心特效
脚本路径:https://apis.nth.ink/cdn/effects/heart.js
这是使用了本站的CDN。您也可以复制代码,并复制到您自己的服务器上。
爆炸球特效
脚本路径:https://apis.nth.ink/cdn/effects/explball.js
和上面一样,您也可以复制代码到您的服务器上。
添加到哪里
如果您在使用wordpress,请把这段代码添加到您主题footer.php的
<?php wp_footer();?>
这行代码的前面。
如果您在自己编辑html,请把这段代码添加到页面的<body></body>之间即可。
