你应该看看JSON-P -当我有这个问题时，这是一个完美的解决方案:

您基本上定义了一个javascript文件来加载所有数据，另一个javascript文件处理并显示数据。这样就摆脱了iframes丑陋的滚动条。

An iframe is still the best way to download cross-domain visual content. With AJAX you can certainly download the HTML from a web page and stick it in a div (as others have mentioned) however the bigger problem is security. With iframes you'll be able to load the cross domain content but won't be able to manipulate it since the content doesn't actually belong to you. On the other hand with AJAX you can certainly manipulate any content you are able to download but the other domain's server needs to be setup in such a way that will allow you to download it to begin with. A lot of times you won't have access to the other domain's configuration and even if you do, unless you do that kind of configuration all the time, it can be a headache. In which case the iframe can be the MUCH easier alternative.

正如其他人提到的，你也可以使用embed标签和object标签，但这并不一定比iframe更高级或更新。

HTML5更倾向于采用web api从跨域获取信息。通常web api只返回数据而不是HTML。

在自己网站的页面中加载另一个网站的页面的关键问题是安全性。这里定义了跨站点安全策略，如果另一个站点将其设置为严格的同源策略，则您将没有机会直接在iframe中加载它。因此，为了找到iframe的替代方案，它们必须能够绕过这个安全策略限制，即使在将来，如果WSC引入任何新组件，它也会有类似的安全限制。

目前，绕过这个问题的最好方法是在逻辑中模拟正常的页面访问，这意味着AJAX +服务器端访问可能是一个不错的选择。您可以在服务器端设置一些代理，获取页面内容并将其加载到iframe中。这是可行的，但不是完美的，因为如果在内容中有任何链接或图像，他们可能无法访问。

通常，如果您尝试在自己的iframe中加载一个页面，则需要检查该页面是否可以在iframe中加载。这篇文章给出了一些如何检查的指导方针。

这似乎也可以工作，尽管W3C指定它不是“用于外部(通常是非html)应用程序或交互式内容”。

基本上有4种方法将HTML嵌入到网页中:

<iframe> An iframe's content lives entirely in a separate context than your page. While that's mostly a great feature and it's the most compatible among browser versions, it creates additional challenges (shrink wrapping the size of the frame to its content is tough, insanely frustrating to script into/out of, nearly impossible to style). AJAX. As the solutions shown here prove, you can use the XMLHttpRequest object to retrieve data and inject it to your page. It is not ideal because it depends on scripting techniques, thus making the execution slower and more complex, among other drawbacks. Hacks. Few mentioned in this question and not very reliable. HTML5 Web Components. HTML Imports, part of the Web Components, allows to bundle HTML documents in other HTML documents. That includes HTML, CSS, JavaScript or anything else an .html file can contain. This makes it a great solution with many interesting use cases: split an app into bundled components that you can distribute as building blocks, better manage dependencies to avoid redundancy, code organization, etc. Here is a trivial example:

<！—其他来源的资源必须启用cors。--> <link rel="import" href="http://example.com/elements.html">

本地兼容性仍然是一个问题，但您可以使用polyfill使其在当前的常绿浏览器中工作。
