wordpress添加打字评论时出现烟花特效

前言

无意中在一个网站上看见的特效,在网上找了一下教程。实验成功特此把整个步骤写出来,据说是js的原因所以其他系统也可以用。

效果

1.首先将下方代码保存在本地以activate-power-mode.js 命名或者下载我写好的 云盘下载   刮刮卡:t8a8

2.将完成的js文件上传到你的网站根目录地址:域名/wp-content/themes/主题名称/static/js

3.在wordpress后台点击外观-主题编辑器-主题页脚(footer.php)输入以下代码,代码的位置选在最下方</body>之前即可

<!--       打字特效 -->
<script src="<?php bloginfo('template_directory'); ?>/static/js/activate-power-mode.js "></script>
<script>
POWERMODE.colorful = true; // ture 为启用礼花特效
POWERMODE.shake = false; // false 为禁用震动特效
document.body.addEventListener('input', POWERMODE);
</script>

样式:

完成之后点击更新文件即可生效,如果没有生效检查一下自己的操作。

实在不行尝试重启服务器和清理浏览器缓存(我自己在修改CSS时经常遇到更改之后没有生效的,这两种方法是我一直做的)

有不懂的可以直接留言,小游的主题已经跟他说过了,晚点会上传。之后会讲他一篇关于主题魔改的文章重新梳理一下发出。

 

感谢大家支持!码字不宜,留个爪印可好~

  1. 我也分享过这个,然后我文章i评论里面有个博主把代码还精简改进了一下。

      我无意中看见的,自己上网查了一下就发出来了,也是因为这个看到了你博客~
