为什么URL转发后该网页显示不一样？

发布于 2024-11-04 04:49:45 字数 894 浏览 5 评论 0原文

我正在开发一个简单的 Google 地图网络应用程序。我已经为该应用程序购买了一个域名（http://www.jcunav.com），在我的测试过程中，该域名旨在简单地转发到我的另一个域名（http://www .codeemporium.com/experiments/map5.html）。在我的 Android Nexus S 上进行测试时，我注意到奇怪的行为 - 如果我访问 http://www.直接使用 codeemporium.com/experiments/map5.html，然后应用程序将按预期显示 - 地图是我想要的大小，单击“关于”链接会弹出一个我想要的大小的对话框。但是，如果我访问 http://www.jcunav.com （请记住，它只是转发到 http://www.codeemporium.com/experiments/map5.html)，地图显示在看起来像是更缩小的级别，按页面底部的“关于”链接会显示一个对话框，该对话框也看起来更缩小。我的问题是，考虑到所有 http://www.jcunav.com ，可能会导致这种情况发生所做的就是转发到 http://www.codeemporium.com/experiments/map5.html ...

你确定你没有进行帧转发吗？我在 firebug 中检查了您提供的每个链接的页面，在我看来您正在框架转发 URL。这会导致您的目标页面在呈现给最终用户时被“包装”在框架中。这很有可能就是它对你不起作用的原因。

以下是转发页面内容的有损版本：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN"
"http://www.w3.org/TR/html4/frameset.dtd">
<html>
<head>
<title>JCU Nav</title>
<META NAME="Keywords" CONTENT="">
<META NAME="Description" CONTENT="">
</head>
    <frameset frameborder="0" framespacing="0" border="0" rows="100%,*">
        <frame name="MYTOPFRAME" src="http://www.codeemporium.com/experiments/map5.html" noresize>
        -- snip --

    </frameset>

</html>

注意框架标记：

<frameset frameborder="0" framespacing="0" border="0" rows="100%,*">
        <frame name="MYTOPFRAME" src="http://www.codeemporium.com/experiments/map5.html" noresize>

这就是转发页面时发生的情况。

由于您的大小调整依赖于 HTML 标记的添加：

<html class="ui-mobile landscape min-width-320px min-width-480px min-width-768px min-width-1024px">

它们在框架转发版本中不起作用，因为它们嵌套在框架内而不是根页面上。

Are you certain you aren't frame-forwarding? I examined the page in firebug for each of the links you provided and it appears to me that you are frame-forwarding the URL. This results in your target page being 'wrapped' in a frame when presented to the end user. Odds are high that this is why it is not working for you.

Here is a somewhat lossy version of what is in the forwarded page:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN"
"http://www.w3.org/TR/html4/frameset.dtd">
<html>
<head>
<title>JCU Nav</title>
<META NAME="Keywords" CONTENT="">
<META NAME="Description" CONTENT="">
</head>
    <frameset frameborder="0" framespacing="0" border="0" rows="100%,*">
        <frame name="MYTOPFRAME" src="http://www.codeemporium.com/experiments/map5.html" noresize>
        -- snip --

    </frameset>

</html>

Notice the frame tag:

<frameset frameborder="0" framespacing="0" border="0" rows="100%,*">
        <frame name="MYTOPFRAME" src="http://www.codeemporium.com/experiments/map5.html" noresize>

This is what happens when you frame forward.

Since your sizing relies on additions to the HTML tag:

<html class="ui-mobile landscape min-width-320px min-width-480px min-width-768px min-width-1024px">

They do not work in the frame-forwarded version because they are nested inside the frame and not on the root page.

这是因为 http://www.jcunav.com 没有转发到 http://www.codeemporium.com/experiments/map5.html，它正在将其加载到框架中：

您需要实际上改变那个框架去做正确的事。

That's because http://www.jcunav.com is not forwarding to http://www.codeemporium.com/experiments/map5.html, it is loading it into a frame:

C:\Documents and Settings\blah>wget -S -O - http://www.jcunav.com/

           => `-'

You'll need to actually change that frame set to do the right thing.
