JS库之Highlight.js的用法详解       highlight.js是一款轻量级的Web代码语法高亮库。下面通过实例代码给大家分享JS库之Highlight.js的用法详解,感兴趣的朋友跟随凡科小编一起学习吧

官网:

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 
 # 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 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 
 pre code 
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 $this- 
 public function show() { 
 printf('my name is %s,age is %d',$this- name,$this- age); 
 /code /pre 
javascript 
 pre 
 code 
 test = { 
 name : function () { 
 return 'hello'; 
 age : function () { 
 return 13; 
 /code 
 /pre 
python 
 pre 
 code 
 # 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 
 pre 
 code 
 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

 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
