实现滚动标题效果 将下面代码加入xiuno的head文件内，就可以实现滚动效果了。代码：<script> //网站打开后延迟开启执行滚动效果 setTimeout(function(){ newtitle(); },2800); function newtitle() { //获取网站的标题 var text=document.title var timerID //标题超过长度后启用滚动 if(text.length>10){ //设置标题，从第二个字获取到末尾+标题的第一个字 document.title=text.substring(1,text.length)+text.substring(0,1); //获取标题长度 text=document.title.substring(0,text.length); //600毫秒后继续调用这个函数进行递归，实现滚动的效果 timerID = setTimeout("newtitle()", 600) } } </script> -

非插件为typecho 文章生成微海报分享 使用方法将文件上传至正使用的主题目录下解压；先在合适的位置插入<a href="javascript:;" class="btn-bigger-cover comiis_poster_a">海报分享</a> <!--样式可以自己改-->再在页脚（ 标签外）插入 <?php if ($this->is('post')) : ?> <!--检查页面是否为内容页--> <?php $this->need('poster.php'); ?> <?php endif; ?>最后一点，poster.php 第 59 行的背景图按需设置，不同主题有不同做法 <div class="comiis_poster_img"><div class="img_time"><?php $this->date('d'); ?><span><?php $this->date('Y'); ?>/<?php $this->date('m'); ?></span></div><img src="此处为你图片的地址" class="vm" id="comiis_poster_image"></div><div class="comiis_poster_tita"><?php $this->title(); ?></div>其他的：默认引入 Mirages.min.js，如果主题自带，可以在 poster.php 注释掉本功能由客户端调用 html canvas 直接生成海报，服务端的压力极小（只需生成一张二维码）。 还是挺不错的，比如说你开发主题就可以直接加上这些（现在带海报分享功能的主题真的不多呢）。文件进Q群3332693或评论下载：{cat_hide}链接：https://pan.baidu.com/s/1Six4r9MLeQpibu_JGE97AQ 提取码：1edj {/cat_hide}

typecho免插件开启评论@小尾巴 在function里面加上这个//获取评论的锚点链接 function get_comment_at($coid) { $db = Typecho_Db::get(); $prow = $db->fetchRow($db->select('parent,status')->from('table.comments') ->where('coid = ?', $coid));//当前评论 $mail = ""; $parent = @$prow['parent']; if ($parent != "0") {//子评论 $arow = $db->fetchRow($db->select('author,status,mail')->from('table.comments') ->where('coid = ?', $parent));//查询该条评论的父评论的信息 @$author = @$arow['author'];//作者名称 $mail = @$arow['mail']; if(@$author && $arow['status'] == "approved"){//父评论作者存在且父评论已经审核通过 if (@$prow['status'] == "waiting"){ echo '<p class="commentReview">（评论正在审核中）</p>'; } echo '<a href="#comment-' . $parent . '">@' . $author . '</a>'; }else{//父评论作者不存在或者父评论没有审核通过 if (@$prow['status'] == "waiting"){ echo '<p class="commentReview">（评论正在审核中）</p>'; }else{ echo ''; } } } else {//母评论，无需输出锚点链接 if (@$prow['status'] == "waiting"){ echo '<p class="commentReview">（评论正在审核中）</p>'; }else{ echo ''; } } }调用方法：在评论输出内容的地方前面放上就行了<?php $parentMail = get_comment_at($comments->coid)?><?php echo $parentMail;?>

通过prism.js实现Typecho代码语法高亮 实现方法 进入prism.js官网的下载页面，Compression level一般选Minified version；Themes根据自己喜好选择；Languages选要用的就好了；全选的话js文件有320KB+，比较大；Plugins按需选择，全选的多个50KB左右。都选好了就可以下载js和css文件了。可以将下载好的js和css文件上传到Typecho的主题目录，即“usr/themes/主题名”目录下，然后登陆进入Typecho的后台，“控制台" --> “外观” --> "编辑当前外观",编辑header.php文件，在标签内插入如下代码：<link rel="stylesheet" href="<?php $this->options->themeUrl('prism.css');?>" /> <script src="<?php $this->options->themeUrl('prism.js');?>"></script>保存文件即可生效。在使用Markdown写文章时，只要在代码块标记`标记后面添加你的代码的语言名，如php、html、python等，就可以实现代码高亮展示。
