动态加载外部网页

Question

I see this site and many others answering similar questions, but often in ways I fail to understand or just do not make sense. And often in contradictory ways (maybe the spec keeps changing?). And I see posts about how to set up cross domain JavaScript communication, but I do not need to communicate with this external content (and I am still not sure if you must have access to the code-base of both child and parent or not, for these hacks to work).

I need to show another person's webpage, on another domain, in a box on my page. SO basically this is like clicking a link, but instead of specifying that the browser should open this in a new tab or a new window, I want the browser to open it in a in-line frame type deal on the current page. So even I know enough about security to know that there are no security/communications issues with this feature.

But assuming that the browser developers have removed this completely reasonable feature, how do I go about doing this? I have heard talk about some Json data type thing being allowed, but still have not figured out exactly what that means. Can I contact any random external page and get some json summery of the page, or how does this work? (I saw an example with Wikipedia, but I was not sure exactly what was being returned, and if any random URL would work just as well).

I can use PHP for this, but that is just stupid. I would basically just be setting up a proxy to access content I am randomly banned from because of the programming language I am trying to access it from.

You are looking for iFrames . Note, however, that there are many security restrictions due to potential cross-site scripting vulnerabilities through improper implementation.

You can change the source of that internal frame by simply editing the source attribute of that iframe
