Question

我搜索了高低的解决方案，但找不到一个。我正在使用Google Docs Viewer来查看PDF文件。这是一个很棒的工具，但我似乎无法在Internet Explorer（7或8）中使用它。我的所有图像都显示为“缺失”图标。如果我在外部查看文件，它似乎加载正常，它将开始工作（我假设因为图像正在缓存）。该文档显示在iframe中，适用于所有其他浏览器。有没有人遇到过让它在IE中运行的解决方案？如果没有，是否有可以显示PPT和PDF文件的替代方案？

Answer 1

我遇到同样的问题，但不认为让用户将网址添加到IE中的可信站点是不可接受的。

幸运的是，我遇到了following post：

如果禁用第三方Cookie，嵌入式版Google文档查看器（gview）将无法正确加载其图像。对于大多数IE用户来说，此问题是一个问题，因为默认情况下它将被禁用。下面我提供一个解决这个问题的工作，至少在谷歌添加p3p之前。有关该问题的原始讨论可以在google docs帮助论坛中找到。

我试过这个，它适用于IE8，IE7和IE6。

我知道这是一个老问题，但由于问题仍然存在，我在这个问题上偶然发现了一个空白网站的答案，这里是{{3}提到的脚本的实际代码，以防万一其他人需要它。（可能会发现，这次是@codeinthehole answer）

# This proxy code is a bypass for an existing flaw in Google Docs Viewer that breaks the functionality
# for some IE users. If you do not wish to use this code, select Google Standard Viewer rather than
# Enhanced Viewer in GDE Settings. Note that viewer toolbar customization options depend on this
# proxy workaround remaining enabled.
# 
# The problem this code addresses is discussed at length on Google's Help Forum:
# http://www.google.com/support/forum/p/Google+Docs/thread?tid=22d92671afd5b9b7&hl=en

# This code is based on the work of Peter Chen. For more information, see:

# and to reflect changes in the viewer since the code was first released.

我发现此问题的唯一解决方案是将https://docs.google.com添加到您信任的互联网网站。

IE浏览器中的Google Docs查看器
