HomeWeb Front-endHTML Tutorial如何在HTML不同的页面中,共用头部与尾部? - 向婷风

一、asp语言和PHP语言

首先制作一个头部文件head.asp,或者一个底部文件foot.asp。如主页是index.asp,调用头部代码是在index.asp文件代码的开始位置(第一个标记后面,

标记前面)增加如下代码:
<span style="color: #0000ff;"><span style="color: #ff00ff;">–  #include file=”head.asp”    –</span><span style="color: #0000ff;">></span> </span>

调用共用底部文件代码是在index.asp文件代码的结束位置(最后一个标记前面)增加如下代码:

<span style="color: #0000ff;"><span style="color: #ff00ff;">–     #include file=”foot.asp”    –</span><span style="color: #0000ff;">></span></span>

 

如果是PHP文件,文件名改为 footer.php即可。

二、html语言
制作一个共用头部文件head.htm或一个共用底部文件foot.htm。如主页文件是index.htm,调用头部和底部文件的方法是:在主页文件代码的开始位置和结束位置分别增加下面的代码:

<span style="color: #0000ff;"><span style="color: #800000;">iframe </span><span style="color: #ff0000;">MARGINWIDTH</span><span style="color: #0000ff;">=0 </span><span style="color: #ff0000;">MARGINHEIGHT</span><span style="color: #0000ff;">=0 </span><span style="color: #ff0000;">HSPACE</span><span style="color: #0000ff;">=0 </span><span style="color: #ff0000;">VSPACE</span><span style="color: #0000ff;">=0 </span><span style="color: #ff0000;">FRAMEBORDER</span><span style="color: #0000ff;">=0 </span><span style="color: #ff0000;">SCROLLING</span><span style="color: #0000ff;">=no </span><span style="color: #ff0000;">src</span><span style="color: #0000ff;">=”head.htm” </span><span style="color: #ff0000;">height</span><span style="color: #0000ff;">=“auto” </span><span style="color: #ff0000;">width</span><span style="color: #0000ff;">="100%"</span><span style="color: #0000ff;">></span><span style="color: #800000;">iframe</span><span style="color: #0000ff;">></span></span>

 

<span style="color: #0000ff;"><span style="color: #800000;">iframe </span><span style="color: #ff0000;">MARGINWIDTH</span><span style="color: #0000ff;">=0 </span><span style="color: #ff0000;">MARGINHEIGHT</span><span style="color: #0000ff;">=0 </span><span style="color: #ff0000;">HSPACE</span><span style="color: #0000ff;">=0 </span><span style="color: #ff0000;">VSPACE</span><span style="color: #0000ff;">=0 </span><span style="color: #ff0000;">FRAMEBORDER</span><span style="color: #0000ff;">=0 </span><span style="color: #ff0000;">SCROLLING</span><span style="color: #0000ff;">=no </span><span style="color: #ff0000;">src</span><span style="color: #0000ff;">=”foot.htm” </span><span style="color: #ff0000;">height</span><span style="color: #0000ff;">="auto" </span><span style="color: #ff0000;">width</span><span style="color: #0000ff;">="100%"</span><span style="color: #0000ff;">></span><span style="color: #800000;">iframe</span><span style="color: #0000ff;">></span></span>

css样式代码如下:

<span style="color: #000000;">*{margin:0;padding:0;}
body{background:white;position:relative;height:100%;color: #777;font-size: 13px;}
img{border:none;display:block;}
li{list-style:none;text-decoration: none;}
.miaov_head{height:36px;width:100%;margin:0 auto;background: black;margin-bottom: 0px;}
.miaov_head  img{width: 30px ;height: 30px;margin-top: 0;margin-left: 130px;}
.miaov_head  ul{float: left;width:900px;height: 36px;margin-top: 0px;color: white;position: absolute;top: 0px;margin-left: 200px;}
.miaov_head  ul li{float: left;padding-left: 80px;margin-left: 0px;color: white;list-style: none; }
.miaov_head  ul li a{color: white;font-size: 14px;text-decoration: none;}
.miaov_head input{position: absolute;top: 5px;margin-left: 1000px;width: 200px;height: 22px;}
.miaov_head a{line-height:36px;color:#777;}
.miaov_head a:hover{color:#555;}</span>

三、script语言--推荐这种
     制作一个共用头部文件head.js和一个共用底部文件foot.js。如主页文件是index.htm,调用头部和底部文件的方法是:在主页文件代码的开始位置和结束位置分别增加下面的代码:

   比如:head.js文件------根据上面的head.html,利用转换工具:http://tool.chinaz.com/Tools/Html_Js.aspx

   html转换为JS:

 以后无论在哪个页面,想调用该头部文件,直接插入head.js文件即可:下面是随便建的一个页面,//MAC.html

四:shtml文件

   1:使用ssi技术页面生成shtml文件,只用在头部文件位置加入,然后修改的时候只要修改header.htm文件就可以了。使用shtml的好处是对搜索引擎比较友好,需要处理的文件在服务器端完成的, 不会加重访问者的浏览器负担。

五:本地合并

  即将HTML硬拆成头、尾、内容三个部分的文件,在预览或者发布之前用脚本手工合并。很久以前用过,没有后台的时候使用效果不错。

六:ajax动态拉取填充

七:web服务器(比如IIS)中设定包含

   比如我们说的SSI,文档后缀名是.shtml的就可以使用include包含。

   SSI(Server Side Include),通常称为"服务器端嵌入"或者叫"服务器端包含",是一种类似于ASP的基于服务器的网页制作技术。默认扩展名是 .stm、.shtm 和 .shtml。SSI就是在HTML文件中,可以通过注释行调用的命令或指针,SSI具有 强大的功能,只要使用一条简单的SSI命令就可以实现整个网站的内容更新,时间和日期的动态显示,以及执行shell和CGI脚本程序等复杂的功能。

八:后台模板引擎处理(字符串拼接)

九:用图片、flash等外部资源做---不推荐,比较麻烦

十:angular js里的的使用

 差不多在静态的html页面中,引入头部和尾部的文件的方法就这么多,列举了一些,其它的感兴趣的可自行钻研。
