This is an extension of an earlier questions I asked, here:
Django - Parse XML, output as HTML fragments for iFrame?
Basically, we're looking at integrating various HTML fragments into a page. We have an small web app generating little fragments for different results/gadgets, at various URLs. This is not necessairly on the same domain as the main page.
I was wondering what's the best way of including these into the main page? We also need the ability to skin the HTML fragments using CSS from the main page.
My initial thought was iFrames, however, I'm thinking the performance of this might not be great, and there's restrictions on CSS/JS manipulation of the included fragments.
Are SSI a better idea? Or should we use php includes? or JS? Any other suggestions? The two main considerations are performance of the main page, and the ability to style/manipulate the included fragments.
Cheers, Victor
This sounds similar to what Facebook Platform applications do. One kind simply uses IFRAMEs, the other takes output from a backend and transforms it -- <fb:whatever> elements are expanded, JavaScript executed, and things like buttons are skinned. You could look at them for an example.
Using IFRAMEs would probably make things complicated. By default you cannot modify styles inside them from the outer frames, but you could probably use something like Google Closure's net.IframeIo to work around that.
I would try loading widgets using cross-domain scripting. Then you can add the widget's content to the page, however you wish, such as inserting it into the DOM.
