背景
随着圣诞节的刚刚过去,我萌生了一个新奇的想法——制作一个弹窗来向大家传达圣诞的祝福。为了实现这个创意,我开始在网上寻找能够完成这一功能的插件。在这个过程中,我偶然发现了尼布大人分享的一篇文章(https://nibbles.cn/wp-plugin-announce.html)。
尼布大人开发的弹窗插件以其简洁的设计风格和恰到好处的功能给我留下了深刻印象。尽管它已经非常出色,但我在使用过程中发现它在某些方面还有提升的空间。因此,我决定在原有插件的基础上进行二次开发,以增强其功能并满足我的特定需求。
插件介绍
如果你对尼布大人的弹窗插件感兴趣,想要了解它的基本功能和实现方式,不妨直接去看看他的原文。这里就是链接。现在,让我们来聊聊我在原有基础上添加的新功能,希望能让这个插件更加实用和有趣。
- 弹窗背景色和透明度自定义
- 可自定义弹窗再次显示的间隔时间
- 可自定义弹窗内容的CSS样式
- 弹窗正文采用经典编辑器(理论上来说可以插入任意HTML内容)

已知问题
测试中发现插件与Lolimeow主题有冲突,具体为插件依赖于jquery.js,但主题阻止了这个脚本的加载,因此为使用该主题的用户现提供以下两项解决方案:
1.编辑主题文件,打开Lolimeow主题文件夹中 module/core/optimize.php
,找到如下代码并注释掉其中的指定行:
//Lolimeow在这里禁止加载了WP自带的jquery.js
function custom_deregister_jquery() {
if (!is_admin()) {
wp_deregister_script('jquery');
}
}
//把下面这一行注释掉
//add_action('wp_enqueue_scripts', 'custom_deregister_jquery', 100);
2.编辑插件文件,打开插件文件夹中 announce.php
,找到如下代码并修改,使插件能使用主题自带的 jquery.min.js
:
//这是插件原本加载js所用到的部分代码:
wp_enqueue_script('announce-script', plugin_dir_url(__FILE__) . 'js/announce.js', array('jquery'), null, true);
//修改为如下内容,使插件能按预期工作:
wp_enqueue_script('announce-script', plugin_dir_url(__FILE__) . 'js/announce.js', array('custom-jquery'), null, true);
