Code Disappears...

Code Disappears...

I have a really weird issue. I'm developing a couple of pages to appear within a 'Bizapp' app (via the web view tab). I've added a simple slider to the top of this page... 


As you can see, when viewed in a browser (and via Safari iOS) it appears fine. But when view within the web view tab in our app, the slider disappears. I've also been testing the app via ScreenFly... 


Which has been doing a pretty good job of emulating the behaviour of the web view (as you can see, the slider does not appear here either). Whilst in this tool I've used it to inspect elements within the page (using Chrome's Inspect elements)... and I've noticed that for some reason, the code for the slider (java AND html) are not there. This is not the first time that I've seen this happen. It seems that any new javascript added to the head just gets stripped out. Making it extremely difficult to use any additional plugins on this page. Has anyone got any ideas why this is happening? Thanks in advance, 

Dan
