问题 I am writing a website with PHP. Since it will need to be accessed by anyone on the network to access the internet I have to create a mobile version. How do I best check if it's a mobile device?

问题 I am creating a web app using jQuery Mobile and PhoneGap.

问题 I have a fluid CSS layout which is rendering badly on an iphone when I change the orientation. (It looks fine when it is refreshed). I am using the code below to refresh the page on orientation change, which works fine - it just feels a little wrong doing so. Is there any way of achieving this without having to reload the entire page?
