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()
