修改效果
自动创建文章目录，支持显示H1-H3共3级标题，标题和目录可以联动：
修改方法
1、在文件 /usr/themes/Joe/public/aside.php 的合适位置增加如下代码，用于在侧边栏创建目录容器
<?php if ($this->is('post') || $this->is('page')) : ?>
<section class="joe_aside__item catalogue">
<div class="joe_aside__item-title">
<svg class="icon" viewBox="0 0 1024 1024" version="1.1" xmlns="http://www.w3.org/2000/svg" p-id="2084" width="18" height="18"><path d="M640 192H224c-17.7 0-32-14.3-32-32s14.3-32 32-32h416c17.7 0 32 14.3 32 32s-14.3 32-32 32zM960 544H224c-17.7 0-32-14.3-32-32s14.3-32 32-32h736c17.7 0 32 14.3 32 32s-14.3 32-32 32zM640 896H224c-17.7 0-32-14.3-32-32s14.3-32 32-32h416c17.7 0 32 14.3 32 32s-14.3 32-32 32zM96 192H64c-17.7 0-32-14.3-32-32s14.3-32 32-32h32c17.7 0 32 14.3 32 32s-14.3 32-32 32zM96 544H64c-17.7 0-32-14.3-32-32s14.3-32 32-32h32c17.7 0 32 14.3 32 32s-14.3 32-32 32zM96 896H64c-17.7 0-32-14.3-32-32s14.3-32 32-32h32c17.7 0 32 14.3 32 32s-14.3 32-32 32z" p-id="2085"></path></svg>
<span class="text">目录</span>
<span class="line"></span>
</div>
<div class="joe_aside__item-contain">
<ul class="catalogue-items">
</ul>
</div>
</section>
<?php endif; ?>2、在Joe主题的设置（ 控制台->外观->设置外观->全局设置->自定义js ）中添加JS代码
function get_catalogs(article_content) {

let titles = [];
article_content.childNodes.forEach((e, index) => {

let node = '<li class="catalogue-item"><a href="javascript:;" id="to-' + catalog[i].id + '" to="' + catalog[i].id + '" title="' + catalog[i].text + '">' + catalog[i].text + '</a>';

}
}
}
document.querySelector('.catalogue-items').innerHTML = catalogue;
$('.catalogue-item > a').on('mouseenter', function () {
$(this).parent().addClass('_active');
});
$('.catalogue-item > a').on('mouseleave', function () {
$(this).parent().removeClass('_active');

// 根据目录定位到标题
$('.catalogue-item > a').on('click', function () {
document.removeEventListener("scroll", autoActive);

break;
}
}
};
document.addEventListener("scroll", autoActive);
}
} else {
// 不是文章，隐藏目录
$('.catalogue').hide();
}3、在Joe主题的设置（控制台->外观->设置外观->全局设置->自定义css）中添加CSS代码
