下载到本地后，新建个页面测试

1、在head中加入css和js的引用

<head>   <title>highlight</title>   <meta http-equiv="content-type" content="text/html;charset=utf-8">   <link rel="stylesheet" href="styles/default.css" rel="external nofollow" rel="external nofollow" >   <script src="highlight.pack.js"></script>   <script>hljs.initHighlightingOnLoad();</script> </head>

2、添加对应要显示的内容

<pre> <code class="python">   # 读取文件内容   def fread(self):     # 如果指针位置大于文件大小，说明是更换了文件     self.filename = self.getLogPath()     if not os.path.isfile(self.filename):       while not self.checkfile() :         time.sleep(5)         self.filename = self.getLogPath()       self.fclose()       self.fopen()       self.pos = 0     self.hd.seek(self.pos,0)     fline = self.hd.readline()     self.pos = self.hd.tell()     return fline.replace("/n","")   # 将文件指针定位到文件尾部   def feof(self):     self.fopen()     # 定位到文件末尾     self.hd.seek(0,2)     #设置指针位置     self.pos = self.hd.tell() </code> </pre>

这里需要把要显示的内容放入到 <pre><code>这里放内容...</code></pre> 这种格式中

默认的话会智能识别，若是识别不出来是什么语言，就需要在<code>标签中加入class

例如 <pre><code class="java" >xxx</code></pre> 即可

下载的时候可以选择你需要的语言，然后再打包，下载后会发现有个style文件夹，里面放了各种不同的显示颜色，为了看看都是些什么样子

我这里弄了个可以选择样式的页面

代码如下

<html> <head>   <title>highlight</title>   <meta http-equiv="content-type" content="text/html;charset=utf-8">   <link rel="stylesheet" href="styles/default.css" rel="external nofollow" rel="external nofollow" >   <script src="highlight.pack.js"></script>   <script>hljs.initHighlightingOnLoad();</script> </head> <body> <div id="changeStyleSelect"></div> PHP <hr> <pre><code class="php"> class Test {   private $name;   private $age;   public function __construct($array) {     $this->name = $array['name'];     $this->age = $array['age'];   }   public function getName() {     return $this->name;   }   public function setName($name) {     $this->name = $name;   }   public function getAge() {     return $this->age;   }   public function show() {     printf('my name is %s,age is %d',$this->name,$this->age);   } } </code></pre> javascript <hr> <pre> <code class="javascript">   test = {     name : function () {       return 'hello';     },     age : function () {       return 13;     }   } </code> </pre> python <hr> <pre> <code class="python">   # 读取文件内容   def fread(self):     # 如果指针位置大于文件大小，说明是更换了文件     self.filename = self.getLogPath()     if not os.path.isfile(self.filename):       while not self.checkfile() :         time.sleep(5)         self.filename = self.getLogPath()       self.fclose()       self.fopen()       self.pos = 0     self.hd.seek(self.pos,0)     fline = self.hd.readline()     self.pos = self.hd.tell()     return fline.replace("/n","")   # 将文件指针定位到文件尾部   def feof(self):     self.fopen()     # 定位到文件末尾     self.hd.seek(0,2)     #设置指针位置     self.pos = self.hd.tell() </code> </pre> java <hr> <pre> <code class="java">   package l2f.gameserver.model;   import java.util.ArrayList;   public abstract class L2Character extends L2Object {    public static final Short ABNORMAL_EFFECT_BLEEDING = 0x0_0_0_1; // not sure    public void moveTo(int x, int y, int z) {     _ai = null;     _log.warning("Should not be called");     if (1 > 5) {      return;     }    }    /** Task of AI notification */    @SuppressWarnings( { "nls", "unqualified-field-access", "boxing" })    public class NotifyAITask implements Runnable {     private final CtrlEvent _evt;     List mList = new ArrayList()     public void run() {      try {       getAI().notifyEvent(_evt, _evt.class, null);      } catch (Throwable t) {       t.printStackTrace();      }     }    }   } </code> </pre>   <script>   styleArr = ["agate.css","androidstudio.css","arduino-light.css","arta.css","ascetic.css","atelier-cave-dark.css","atelier-cave-light.css","atelier-dune-dark.css","atelier-dune-light.css","atelier-estuary-dark.css","atelier-estuary-light.css","atelier-forest-dark.css","atelier-forest-light.css","atelier-heath-dark.css","atelier-heath-light.css","atelier-lakeside-dark.css","atelier-lakeside-light.css","atelier-plateau-dark.css","atelier-plateau-light.css","atelier-savanna-dark.css","atelier-savanna-light.css","atelier-seaside-dark.css","atelier-seaside-light.css","atelier-sulphurpool-dark.css","atelier-sulphurpool-light.css","brown-paper.css","codepen-embed.css","color-brewer.css","dark.css","darkula.css","default.css","docco.css","dracula.css","far.css","foundation.css","github.css","github-gist.css","googlecode.css","grayscale.css","gruvbox-dark.css","gruvbox-light.css","hopscotch.css","hybrid.css","idea.css","ir-black.css","kimbie.dark.css","kimbie.light.css","magula.css","mono-blue.css","monokai.css","monokai-sublime.css","obsidian.css","paraiso-dark.css","paraiso-light.css","pojoaque.css","purebasic.css","qtcreator_dark.css","qtcreator_light.css","railscasts.css","rainbow.css","school-book.css","solarized-dark.css","solarized-light.css","sunburst.css","tomorrow.css","tomorrow-night.css","tomorrow-night-blue.css","tomorrow-night-bright.css","tomorrow-night-eighties.css","vs.css","xcode.css","xt256.css","zenburn.css"];   selectHtml = [];   selectHtml.push('<select id="changeStyle">');   for(i in styleArr) {     OptionValue = styleArr[i];     selectHtml.push('<option value="' + OptionValue +'" >'+ OptionValue +'</option>');   }   selectHtml.push('</select>');   selectHtmlString = selectHtml.join("");   document.getElementById('changeStyleSelect').innerHTML = selectHtmlString;   obj = document.getElementById('changeStyle');   obj.addEventListener("change",function(event){     var value = this.options[this.options.selectedIndex].value;       l = document.createElement('link');     l.setAttribute('href','styles/'+value);     l.setAttribute('rel','stylesheet');     document.head.appendChild(l);   });   </script> </body> </html>
