所以我试图运行一个显示客户端安全摄像头源的网页。但是它不能正确渲染，只显示背景。我有一种感觉，它与iframe标记的限制有关，因为在线使用其他iframe测试小工具我得到相同的结果。其他客户端使用不同接口的摄像头源，我的解决方案对他们来说工作正常。有iframe的替代品吗？Iframe无法正确呈现
编辑：页面直接访问时实际呈现完美，而不是通过iframe。
edit2：此处的流行要求是安全Feed网站的来源。我没有发布我的iframe代码，因为无论我用于iframe，它都不会显示。

iframe标记不会改变浏览器渲染包含页面的能力。如果它不在iframe中呈现，它将不会呈现。 – Vetsin 2010-12-22 18:17:42
那就是我的想法。但它能够很好地直接访问它。而且根本无法在iframe中呈现。这是在多个浏览器和多台机器上检查的。 – Matt 2010-12-22 18:21:43
也许我错了，该代码是使用框架和JavaScript引用它们。也许JavaScript和iframe中的框架之间存在渲染问题？ – Vetsin 2010-12-22 19:41:26
