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 of each implementation.

Syntax

var successBool = window.navigator.vibrate(pattern);
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.

Examples

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.

1. Beginning in Chrome 55, this is not supported in cross-origin iframes.

2. Beginning in Chrome 60, this method requires a user gesture. Otherwise it returns false.

3. Until Firefox 26 included, when the vibration pattern was too long or any of its elements too large, Firefox threw an exception instead of returning false (bug 884935).

4. From Firefox 32 onwards, when the vibration pattern is too long or any of its elements too large, it returns true but truncates the pattern (bug 1014581).

5. Beginning in Opera 47, this method requires a user gesture. Otherwise it returns false.

6. Beginning in version 55, this is not supported in cross-origin iframes.

7. Beginning in version 60, this method requires a user gesture. Otherwise it returns false.
