Mozilla Firefox vibrates

This winter, we had a chance to notice such useful news in the mobile Firefox, as the control over the battery charge and the management of mobile communications and SMS . The day before yesterday , the Mozilla Hacks blog posting that the developers of Firefox 11 also provided the sites with an interface that controls the vibration of a mobile phone.

In the simplest case, it is sufficient to set the duration of the vibration, expressed in milliseconds, using javascript:

navigator.mozVibrate(1000); 

A slightly more complicated vibration is set by means of an array, the odd elements of which specify the duration of the vibration, and even-numbered ones - the duration of the subsequent pause. Here is an example of a brief double vibration:
')

 navigator.mozVibrate([200, 100, 200, 100]); 

To immediately stop the vibration of a mobile phone (without waiting for the end of the specified durations), it is enough to transfer a zero duration or an empty array to the same method:

 navigator.mozVibrate(0); navigator.mozVibrate([]); 

The draft of the relevant standard is published on the W3C website .
