Detect whether browser has keyboard/arrow keys in web page

Question

I have a full-screen game in HTML+JavaScript, which uses the arrow keys as primary controls. This cannot be used on keyboardless Android devices (I haven\'t tested on iOS),

Answer 1

You could use javascript to find out the height of the windows view port and then us an if statement saying:

if ($(window).height() <= "960")) {
    //Your code to display keyboard controls
    //P.S. 960 is height of iPhone 4+ screen
}

Edit: Left out ) at end of $(window).height() <= "960"
