The Navigator.vibrate() method pulses the vibration hardware on the device, if such hardware exists. If the device doesn't support vibration, this method has no effect. If a vibration pattern is already in progress when this method is called, the previous pattern is halted and the new one begins instead.

If the method was unable to vibrate because of invalid parameters, it will return false, else it returns true. If the pattern leads to a too long vibration, it is truncated: the max length depends on the implementation.


var successBool = window.navigator.vibrate(pattern);
Provides a pattern of vibration and pause intervals. Each value indicates a number of milliseconds to vibrate or pause, in alternation. You may provide either a single value (to vibrate once for that many milliseconds) or an array of values to alternately vibrate, pause, then vibrate again. See Vibration API for details.

Passing a value of 0, an empty array, or an array containing all zeros will cancel any currently ongoing vibration pattern.


window.navigator.vibrate(200); // vibrate for 200ms
window.navigator.vibrate([100,30,100,30,100,30,200,30,200,30,200,30,100,30,100,30,100]); // Vibrate 'SOS' in Morse.
