If your device supports vibration, then <strong>skip</strong> this test. An implementation supporting this API but running on a device that cannot vibrate must silently ignore the call (we test that it doesn't throw). </p> <div id='log'></div> <script src='/resources/testharness.js'></script> <script src='/resources/testharnessreport.js'></script> <script src='/common/vendor-prefix.js' data-prefixed-objects='[{"ancestors":["navigator"], "name":"vibrate"}]'></script> <script> if (undefined !== navigator.vibrate) { test(function () { assert_true(navigator.vibrate(1000), "vibrate() returns true when vibration is not supported"); }, "Calling vibrate returns true"); } </script> </body> </html>
