highlight.js的简单使用方法

官网：https://highlightjs.org/

下载地址：https://highlightjs.org/download/

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"><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 = 0self.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"><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 = 0self.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>
