Typecho实现评论显示操作系统和评论来源 首先打开 functions.php 文件，粘贴下面的代码：// 获取浏览器信息 function getBrowser($agent) { if (preg_match('/MSIE\s([^\s|;]+)/i', $agent, $regs)) { $outputer = 'Internet Explore'; } else if (preg_match('/FireFox\/([^\s]+)/i', $agent, $regs)) { $str1 = explode('Firefox/', $regs[0]); $FireFox_vern = explode('.', $str1[1]); $outputer = 'FireFox'; } else if (preg_match('/Maxthon([\d]*)\/([^\s]+)/i', $agent, $regs)) { $str1 = explode('Maxthon/', $agent); $Maxthon_vern = explode('.', $str1[1]); $outputer = 'MicroSoft Edge'; } else if (preg_match('#360([a-zA-Z0-9.]+)#i', $agent, $regs)) { $outputer = '360 Fast Browser'; } else if (preg_match('/Edge([\d]*)\/([^\s]+)/i', $agent, $regs)) { $str1 = explode('Edge/', $regs[0]); $Edge_vern = explode('.', $str1[1]); $outputer = 'MicroSoft Edge'; } else if (preg_match('/UC/i', $agent)) { $str1 = explode('rowser/', $agent); $UCBrowser_vern = explode('.', $str1[1]); $outputer = 'UC Browser'; } else if (preg_match('/QQ/i', $agent, $regs)||preg_match('/QQ Browser\/([^\s]+)/i', $agent, $regs)) { $str1 = explode('rowser/', $agent); $QQ_vern = explode('.', $str1[1]); $outputer = 'QQ Browser'; } else if (preg_match('/UBrowser/i', $agent, $regs)) { $str1 = explode('rowser/', $agent); $UCBrowser_vern = explode('.', $str1[1]); $outputer = 'UC Browser'; } else if (preg_match('/Opera[\s|\/]([^\s]+)/i', $agent, $regs)) { $outputer = 'Opera'; } else if (preg_match('/Chrome([\d]*)\/([^\s]+)/i', $agent, $regs)) { $str1 = explode('Chrome/', $agent); $chrome_vern = explode('.', $str1[1]); $outputer = 'Google Chrome'; } else if (preg_match('/safari\/([^\s]+)/i', $agent, $regs)) { $str1 = explode('Version/', $agent); $safari_vern = explode('.', $str1[1]); $outputer = 'Safari'; } else{ $outputer = 'Google Chrome'; } echo $outputer; } // 获取操作系统信息 function getOs($agent) { $os = false; if (preg_match('/win/i', $agent)) { if (preg_match('/nt 6.0/i', $agent)) { $os = 'Windows Vista&nbsp;·&nbsp;'; } else if (preg_match('/nt 6.1/i', $agent)) { $os = 'Windows 7&nbsp;·&nbsp;'; } else if (preg_match('/nt 6.2/i', $agent)) { $os = 'Windows 8&nbsp;·&nbsp;'; } else if(preg_match('/nt 6.3/i', $agent)) { $os = 'Windows 8.1&nbsp;·&nbsp;'; } else if(preg_match('/nt 5.1/i', $agent)) { $os = 'Windows XP&nbsp;·&nbsp;'; } else if (preg_match('/nt 10.0/i', $agent)) { $os = 'Windows 10&nbsp;·&nbsp;'; } else{ $os = 'Windows X64&nbsp;·&nbsp;'; } } else if (preg_match('/android/i', $agent)) { if (preg_match('/android 9/i', $agent)) { $os = 'Android Pie&nbsp;·&nbsp;'; } else if (preg_match('/android 8/i', $agent)) { $os = 'Android Oreo&nbsp;·&nbsp;'; } else { $os = 'Android&nbsp;·&nbsp;'; } } else if (preg_match('/ubuntu/i', $agent)) { $os = 'Ubuntu&nbsp;·&nbsp;'; } else if (preg_match('/linux/i', $agent)) { $os = 'Linux&nbsp;·&nbsp;'; } else if (preg_match('/iPhone/i', $agent)) { $os = 'iPhone&nbsp;·&nbsp;'; } else if (preg_match('/mac/i', $agent)) { $os = 'MacOS&nbsp;·&nbsp;'; }else if (preg_match('/fusion/i', $agent)) { $os = 'Android&nbsp;·&nbsp;'; } else { $os = 'Linux&nbsp;·&nbsp;'; } echo $os; }comments.php 中找到合适位置（比如评论作者的后面）添加以下代码：<?php getOs($comments->agent); ?><?php getBrowser($comments->agent); ?>

Typecho自定义后台编辑器功能 上面的增加按钮很简单，append一个li标签就可以实现，主要是在于向文本框中插入内容，以及输入键盘按键也能实现插入对应的功能。使用方法首先在你的主题 functions.php 里增加一个插件函数，这个函数的用途是在编辑文章和编辑页面里面引入自定义JSTypecho_Plugin::factory('admin/write-post.php')->bottom = array('Editor', 'edit'); Typecho_Plugin::factory('admin/write-page.php')->bottom = array('Editor', 'edit'); class Editor { public static function edit() { echo "<script src='" . Helper::options()->themeUrl . '/typecho/editor/joe.extend.js' . "'></script>"; echo "<script src='" . Helper::options()->themeUrl . '/typecho/editor/joe.editor.js' . "'></script>"; } }下面的 joe.extend.js 没压缩也没加密，下面是 joe.extend.js 源码(function ($) { $.fn.extend({ /* 按键盘实现插入内容 */ shortcuts: function () { this.keydown(function (e) { var _this = $(this); e.stopPropagation(); if (e.altKey) { switch (e.keyCode) { case 67: _this.insertContent('[code]' + _this.selectionRange() + '[/code]'); break; } } }); }, /* 插入内容 */ insertContent: function (myValue, t) { var $t = $(this)[0]; if (document.selection) { this.focus(); var sel = document.selection.createRange(); sel.text = myValue; this.focus(); sel.moveStart('character', -l); var wee = sel.text.length; if (arguments.length == 2) { var l = $t.value.length; sel.moveEnd('character', wee + t); t <= 0 ? sel.moveStart('character', wee - 2 * t - myValue.length) : sel.moveStart('character', wee - t - myValue.length); sel.select(); } } else if ($t.selectionStart || $t.selectionStart == '0') { var startPos = $t.selectionStart; var endPos = $t.selectionEnd; var scrollTop = $t.scrollTop; $t.value = $t.value.substring(0, startPos) + myValue + $t.value.substring(endPos, $t.value.length); this.focus(); $t.selectionStart = startPos + myValue.length; $t.selectionEnd = startPos + myValue.length; $t.scrollTop = scrollTop; if (arguments.length == 2) { $t.setSelectionRange(startPos - t, $t.selectionEnd + t); this.focus(); } } else { this.value += myValue; this.focus(); } }, /* 选择 */ selectionRange: function (start, end) { var str = ''; var thisSrc = this[0]; if (start === undefined) { if (/input|textarea/i.test(thisSrc.tagName) && /firefox/i.test(navigator.userAgent)) str = thisSrc.value.substring(thisSrc.selectionStart, thisSrc.selectionEnd); else if (document.selection) str = document.selection.createRange().text; else str = document.getSelection().toString(); } else { if (!/input|textarea/.test(thisSrc.tagName.toLowerCase())) return false; end === undefined && (end = start); if (thisSrc.setSelectionRange) { thisSrc.setSelectionRange(start, end); this.focus(); } else { var range = thisSrc.createTextRange(); range.move('character', start); range.moveEnd('character', end - start); range.select(); } } if (start === undefined) return str; else return this; } }); })(jQuery);上面的shortcuts方法主要用于实现按下键盘插入内容接着看 joe.edit.js的内容/* 增加自定义功能 */ const items = [ { title: '回复可见', id: 'wmd-hide-button', svg: '<svg t="1612402690962" class="icon" viewBox="0 0 1024 1024" version="1.1" xmlns="http://www.w3.org/2000/svg" p-id="15751" width="20" height="20"><path d="M554.666667 438.101333V277.333333h-85.333334v160.768L330.112 357.717333l-42.666667 73.898667L426.666667 512l-139.221334 80.384 42.666667 73.898667L469.333333 585.898667V746.666667h85.333334v-160.768l139.221333 80.384 42.666667-73.898667L597.333333 512l139.221334-80.384-42.666667-73.898667L554.666667 438.101333z" p-id="15752" fill="#9b9b9b"></path></svg>', text: '\n[@hide]这里的内容回复后才能看见[/hide]\n' } ]; items.forEach(_ => { let item = $(`<li class="wmd-button" id="${_.id}" title="${_.title}">${_.svg}</li>`); item.on('click', function () { $('#text').insertContent(_.text); }); $('#wmd-button-row').append(item); });

推荐一个好用代码-高亮JS库 插件官网是 https://prismjs.com/使用很简单，首先去官网下载js文件和css文件然后引入下载的文件<link rel="stylesheet" href="prism.js"> <script src="prism.js"></script>需要注意的是高亮的代码形式需要是这样：<pre><code class="language-css">p { color: red }</code></pre>

Typecho Joe主题的文章内容如何增加目录 概述文章目录功能是通过AutocJs来实现的，具体可以看：https://github.com/yaohaixiao/AutocJS配置步骤首先进入网站后台，点击更换外观，点击全局设置然后在下方找到 自定义增加里内容（非必填），填入下面代码<style type="text/css"> .outline-outside-modal-opened { z-index: 10000 !important; left: 0; width: 300px !important; } </style> <link rel="stylesheet" href="https://fastly.jsdelivr.net/gh/yaohaixiao/autocjs/dist/css/autoc.min.css">3.最后在自定义末尾位置内容（非必填） 中填入下面代码<script src="https://fastly.jsdelivr.net/gh/yaohaixiao/autocjs/dist/autoc.min.js"></script> <script> // 文章导航 if ( $(".joe_detail__article").length > 0 ){ // 创建 Outline 实例 let navigation = new AutocJs({ // 文章正文 DOM 节点的 ID 选择器 article: '.joe_detail__article', // 要收集的标题选择器 selector: 'h1,h2,h3,h4,h5,h6', // 侧边栏导航的标题 title: '文章导读', // 文章导读导航的位置 // outside - 以侧边栏菜单形式显示（默认值） // inside - 在文章正文一开始的地方显示 position: 'outside', // 标题图标链接的 URL 地址 // （默认）没有设置定制，点击链接页面滚动到标题位置 // 设置了链接地址，则不会滚动定位 anchorURL: '', // 链接的显示位置 // front - 在标题最前面（默认值） // back - 在标题后面 anchorAt: 'back', // 是否生成文章导读导航 isGenerateOutline: true, // 是否在文章导读导航中显示段落章节编号 isGenerateOutlineChapterCode: false, // 是否在正文的文章标题中显示段落章节编号 isGenerateHeadingChapterCode: false, // 是否在正文的文章标题中创建锚点 isGenerateHeadingAnchor: false }); } </script>
