Phonegap entry-8 compass

I haven't updated my blog for a long time. I don't want to write, don't want to get it, and I'm lazy.

Today we will introduce the compass.

Compass

Obtain the current orientation of the device. The compass is a sensor that detects the direction or orientation of the device. The measurement unit is degree, and the value ranges from 0 degrees to 359.99 degrees.

There are several methods for this object:

Navigator. Compass. getcurrentheading (compasssuccess, compasserror, compassoptions );

Obtains the current orientation of the compass.

Compass. watchheading

 

 
VaR watchid = navigator. Compass. watchheading (compasssuccess, compasserror, [compassoptions]);
 

Obtain the angle of the orientation of the compass at a fixed interval.

 

Compass. clearwatch

 

Navigator. Compass. clearwatch (watchid );
 

Stop the compass monitoring that the watch ID parameter points.

 

This is similar to the accelerometer accelerator described earlier, so it will not be explained in detail.
