The XHTML that hosts this applet is shown in Listing 2 and is just a trivial use of HTML event handlers and iframe.

The iframe approach was the common way to get Ajax functionality before the XMLHttpRequest object was implemented everywhere.

This line uses the document.write() method to put a small 0*0 pixel hidden iFrame on the Web page.
该行代码使用 document.write()方法将一个较小的隐藏的 iFrame（0*0像素）放置在 Web 页面上。
You can solve this issue by using either a hidden iFrame or AJAX to refresh the portal page inside the portlet.
可以使用隐藏iFrame或AJAX在Portlet内刷新门户页，从而解决此问题。
You must encode the iFrame name to prevent potential conflicts when more than one instance of the portlet is on page.
必须对 iFrame名称进行编码，以防止在页面上存在Portlet的多个实例时出现冲突。
The simplest way to do this is to use an IFRAME on your Web page and set the SRC attribute using the same URL-based technique I described.
最简单的方法就是在Web页上使用IFRAME，并使用我介绍过的基于URL的相同技术来设置SRC属性。
From the portal's perspective, this iFrame is a reserved rectangle on the portal page, and the portal has no control of the content or the format.
从门户的角度而言，此i Frame是门户页上的一个保留方框，门户不能控制其内容或格式。
Of course, this behavior is not the one we want to keep in the portal. Instead, you want to have the Web client configured to use the whole iFrame window.
当然，这个行为并不是我们要在门户中保留的，相反，您希望将Web客户端配置为使用整个 iFrame 窗口。
You can now apply SVG transforms to any old Web browser object so that for example you might decide to rotate an IFRAME by 45 degrees, a trick that would usually require the Canvas facility.
您现在可以向任何一个旧Web浏览器对象应用SVG转换，例如，这样您可以决定将IFRAME 旋转45度，而这通常需要使用 Canvas 工具。
