- The MSGesture object is undefined.
In Internet Explorer 10 on Windows 8, you can use the aria-haspopup DOM property to simulate mouse hover functionality in touch-based scenarios. You can read more about this behavior in Using aria-haspopup to simulate hover on touch-enabled devices.
This use for aria-haspopup is not supported in Windows 7. Adding "aria-haspopup="true"" to an element doesn't simulate mouse hover in Internet Explorer 10 on Windows 7. However, the aria-haspopup property is still supported for reporting accessibility information to assistive technologies.
