HTML5 App Screen Sleep/Timeout on iPad

Question

We\'re currently developing an HTML 5 app for the iPad and looking for a method to prevent the screen from going to standby/sleep. I understand this is possible with a nativ

Answer 1

Nope, you can't do this with a plain website/web app.

One option could be to create a native app containing simply a UIWebView. The native app would contain code to load your web app into the webview and disable the idle timer. (It's the idle timer that puts the iPad to sleep.)

Answer 2

Adjusted settings to not let the iPad lock the screen. Fired up a page that uses websockets. In an simple interval I used the socket to send and recieve a message every 60s. Worked for a couple of hours, then I closed it.

I also tried to switch tabs. Worked.

Answer 3

Standby/sleep modes are rooted to the OS, so it's pretty much impossible to achieve with HTML5. Why would you do this anyway? Maybe you could think of a timeout function in case the device was in standby/sleep and came back. This answer looks useful but I haven't yet test it.
