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; 
    } 
  }

    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()
