Question

我在一个名为Test.aspx的页面上有一个iframe，它指向一个url src =“IframeTest.aspx”，它位于同一目录中，但我不断收到错误消息：

HTTP 404.您要查找的资源（或其中一个依赖项）可能已被删除，名称已更改或暂时不可用。请查看以下网址，确保拼写正确。

修改

iframe似乎在IE9中显示但在Mozilla中没有显示，我动态地静态添加两个iframe进行测试，发现两个iframe在IE9中工作但在Mozilla中根本没有。

我创建了一个测试网站，尝试重现您的错误，其中包括以下内容：

<强> Test.aspx文件

<iframe src="IframeTest.aspx" style="border:1px solid black"></iframe>

<强> IframeTest.aspx

<p>Hello World!</p>

如果没有您的确切代码且不知道您的文件路径，我将无法重现您的错误。

我建议不要在同一目录中的.HTML中创建这些页面，其中只有 iframe in test.html 和＆lt; p＆gt; Hello World＆lt; / p＆gt;在IframeTest.html中。这可以帮助您通过将代码剥离为零来了解问题所在。

iframe无法使用Mozilla中设置的src属性
