WP Rocket特定页面排除JS延迟插件失效求助

1. 修复核心语法错误 #

你的代码中把PHP逻辑运算符&&错误写成了HTML实体&&，这会直接导致页面匹配条件失效，插件无法正确识别目标页面规则。

修改以下两行代码：

( function_exists( 'is_page' ) && is_page( $excluded_slugs ) ) 
|| ( function_exists( 'is_single' ) && is_single( $excluded_slugs ) )

2. 优化页面匹配逻辑 #

如果你的首页使用自定义模板home-v4.php、tablets页面使用tablet.php，建议同时保留首页判断和模板判断，确保覆盖所有场景：

if ( 
    ( function_exists( 'is_page' ) && is_page( $excluded_slugs ) ) 
    || ( function_exists( 'is_single' ) && is_single( $excluded_slugs ) )
    || is_front_page()
    || is_page_template('home-v4.php')
    || is_page_template('tablet.php')
) {

3. 确保JS脚本匹配准确 #

WP Rocket的延迟JS排除对匹配字符串要求严格，建议使用更稳定的匹配方式：

• jQuery直接用脚本句柄jquery（比文件名更可靠，避免文件名版本变化导致匹配失效）
• Slick保留slick.min.js即可，若失效可尝试其注册句柄slick或slick-js

修改排除脚本部分：

$exclusions[] = 'jquery';
$exclusions[] = 'slick.min.js';
// 若slick仍延迟，替换为句柄：$exclusions[] = 'slick';

4. 强制清除缓存 #

修改代码后必须彻底清除WP Rocket页面缓存、浏览器缓存，若使用了服务器缓存（如Nginx、Cloudflare）也需同步清除，否则旧缓存会掩盖修改效果。

add_filter( 'rocket_delay_js_exclusions',  __NAMESPACE__ . '\exclude_from_delay' );

额外排查点 #

• 检查是否有其他缓存工具（如CDN、服务器缓存），需同步清除缓存。
• 确认slick.min.js的实际加载路径，若路径包含目录（如/js/slick.min.js），可尝试用完整路径片段匹配，WP Rocket支持部分字符串匹配。
