本篇文章给大家分享的是有关如何在JavaScript中使用Highlight.js,小编觉得挺实用的,因此分享给大家学习,希望大家阅读完这篇文章后可以有所收获,话不多说,跟着小编一起来看看吧。
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>
