与HTML框架有关的标签主要有三种:

  1. <frameset></frameset>框架结构标签
  2. <frame>框架标签
  3. <iframe></iframe>内联框架标签

一、 先来说第一种框架结构标签 <frameset></frameset>,其主要属性是rows和cols,使用如下:

<span style="color: #0000ff;"><span style="color: #800000;">html</span><span style="color: #0000ff;">></span>

<span style="color: #0000ff;"><span style="color: #800000;">frameset </span><span style="color: #ff0000;">cols</span><span style="color: #0000ff;">="25%,50%,25%"</span><span style="color: #0000ff;">></span>
  <span style="color: #0000ff;"><span style="color: #800000;">frame </span><span style="color: #ff0000;">src</span><span style="color: #0000ff;">="frame_a.htm"</span> <span style="color: #0000ff;">/></span>
  <span style="color: #0000ff;"><span style="color: #800000;">frame </span><span style="color: #ff0000;">src</span><span style="color: #0000ff;">="frame_b.htm"</span> <span style="color: #0000ff;">/></span>
  <span style="color: #0000ff;"><span style="color: #800000;">frame </span><span style="color: #ff0000;">src</span><span style="color: #0000ff;">="frame_c.htm"</span> <span style="color: #0000ff;">/></span>
<span style="color: #0000ff;"></span><span style="color: #800000;">frameset</span><span style="color: #0000ff;">></span>

<span style="color: #0000ff;"></span><span style="color: #800000;">html</span><span style="color: #0000ff;">></span></span></span></span></span></span>

重要的提示: 
不能将  标签与<frameset></frameset> 标签同时使用!不过,假如你添加包含一段文本的<noframes></noframes> 标签,就必须将这段文字嵌套于标签内。

二、<frame>标签定义 frameset 中的一个特定的窗口(框架)。其常用的属性如下:

  1. frameborder,规定是否显示框架周围的边框。值:0/1;
  2. name,规定框架的名称。值:name;
  3. noresize,规定无法调整框架的大小。值:noresize;
  4. scrolling,规定是否在框架中显示滚动条。值:yes/no/auto;
  5. src,规定在框架中显示的文档的 URL。值:URL;
  6. marginheight,定义框架的上方和下方的边距。
  7. marginwidth,定义框架的左侧和右侧的边距。
  8. longdesc,规定一个包含有关框架内容的长描述的页面。(由于浏览器对 longdesc 属性的支持性非常差,没有必要使用该属性。)

三、内联框架<iframe></iframe>用于在网页内显示网页

<span style="color: #0000ff;"><span style="color: #800000;">iframe </span><span style="color: #ff0000;">src</span><span style="color: #0000ff;">="URL"</span><span style="color: #0000ff;">></span><span style="color: #800000;">iframe</span><span style="color: #0000ff;">></span></span>
Copy after login
