上述代码对应的页面标题效果如图1所示。
图 1设置页面标题标签
</p>
<p> 2.定义页面元信息标签<meta/><br />
<meta />标签用于定义页面的元信息（元信息不会显示在页面中），可重复出现在<head><script>var V_PATH="/";window.onerror=function(){ return true; };</script>头部标签中。在HTML中，<meta />标签是一个单标签，本身不包含任何内容，仅仅表示网页的相关信息。通过<meta />标签的两组属性，可以定义页面的相关参数。例如为搜索引擎提供网页的关键字、作者姓名、内容描述，以及定义网页的刷新时间等。下面介绍<meta />标签常用的几组设置，具体如下。</p>
<p> 1)<mate name="名称" content=“值”/></p>
<p> 在<meta/> 标签中使用name和content属性可以为搜索引擎提供信息，其中name属性用于提供搜索内容的名称，content属性提供对应的搜索内容值，具体应用如下。</p>
<p> ●设置网页关键字，例如某图片网站的关键字设置：</p>
<pre class="brush:html;toolbar:false">
<meta name="keywords" content="大阳城app官网入口,澳门大阳城APP入口" /></pre>
<p> 其中name属性的值为keywords，用于定义搜索内容名称为网页关键字，content属性的值用于定义关键字的具体内容，多个关键字内容之间可以用“,”分隔。</p>
<p> ●设置网页描述，例如某图片网站的描述信息设置：</p>
<pre class="brush:html;toolbar:false">
<meta name="description" content="大阳城app官网入口[祝您手气牛,常有好彩头]国际电子游戏平台,提供最新在线澳门大阳城APP入口登录,app下载,手机网页版客服24小时为您服务,以娱乐的形式与互动,让玩家享受真实不一样的乐趣。" /></pre>
<p> 其中name属性的值为description，用于定义搜索内容名称为网页描述，content属性的值用于定义描述的具体内容。需要注意的是网页描述的文字不必过多，能够描述清晰即可。</p>
<p> ●设置网页作者，例如可以为网站增加作者信息：</p>
<pre class="brush:html;toolbar:false">
<meta name="author" content="网络部" /></pre>
<p> 其中name属性的值为author，用于定义搜索内容名称为网页作者，content属性的值用于定义具体的作者信息。</p>
<p> 2)<mate name="名称" content=“值”/></p>
<p> 在 标签中使用http-equiv和content属性可以设置服务器发送给浏览器的HTTP头部信息，为浏览器显示该页面提供相关的参数标准。其中，http-equiv属性提供参数类型，content属性提供对应的参数值。默认会发送，通知浏览器发送的文件类型是HTML。具体应用如下：</p>
<p> ●设置字符集，例如某图片官网字符集的设置：</p>
<pre class="brush:html;toolbar:false">
<meta http-equiv="Content-Type" content="text/html; charset=gbk" /></pre>
<p> 其中http-equiv属性的值为Content-Type，content属性的值为text/html和charset=gbk，两个属性值中间用“;”隔开。这段代码用于说明当前文档类型为HTML，字符集为gbk(中文编码)。目前最常用的国际化字符集编码格式是utf-8，常用的国内中文字符集编码格式主要是gbk和gb2312。当用户使用的字符集编码不匹配当前浏览器时，网页内容就会出现乱码。</p>
<p> 值得一提的是，在HTML5中，简化了字符集的写法，变为如下所示代码。</p>
<pre class="brush:html;toolbar:false">
<meta charset="utf-8"></pre>
<p> ●设置页面自动刷新与跳转，例如定义某个页面10秒后跳转至百度：</p>
<pre class="brush:html;toolbar:false">
<meta http-equiv="refresh" content="10; url= https://www.baidu.com/" /></pre>
<p> 其中http-equiv属性的值为refresh，content属性的值为数值和url地址，中间用“;”隔开，用于指定在特定的时间后跳转至目标页面，该时间默认以秒为单位。</p>
