我正在学习在javascript中编写摇动功能。但我不知道如何检测和计算用户所做的震动次数，有人可以帮我一把吗？

    shake.startWatch(onShake);

    function onShake()
    {
      alert('Shook');
    }

    // Stop watching for shaking event
    shake.stopWatch();

Answer 1

这是一种可以计算震动的方法。

shake.startWatch(onShake);
var count = 0;
function onShake()
{
  alert('Shook');
  count++ //increases count by 1 each time the function is called.
}

// Stop watching for shaking event
shake.stopWatch();
