Codeigniter - Facebook - JQuery Mobile problem
I have encountered a similar problem with JQM and the url #hash. I was able to use the anchor tag's rel attribute:
<a href="http://website.com" rel="external">Link Me</a>You may also want to try data-ajax="false"
AND/OR with the JQM changePage() method:
$.mobile.changePage(url, { changeHash:false});
Where url is the path as a String (relative or absolute).
As for the underscore, this is a big problem for CodeIgniter since any method starting with an _ is a private method.
Admittedly, I have never used the FaceBook PHP API. So, your problem may be out of my scope of knowledge.
Ah yes, the infamous hash symbol at the end of the URL bug. Let me guess, your testing this on an Android emulator using the built in webkit browser. It will work on an actual device, also try this on another emulator version.
I suspect that there is very little known about this, but Iv'e seen this little issue in several questions on SO and Iv'e encountered it in my own tests. There is definitely something wrong here.
