我只想在人们不空闲时更新 useronline 数据库上的时间戳(键盘鼠标活动一段时间 - 我为此使用 jquery 插件)对我来说问题是我无法清除函数的间隔所以在我下面的测试脚本中,当它开始计数时它永远不会停止,即使再次激活它也会启动另一个计数器,这样它的计数速度就会提高一倍。我应该如何停止那个计时器?它就像计数器在空闲时从未启动过一样 - 所以它找不到它来停止它。

在真正的脚本中,计数器将是 $.get()-ing 更新 mysql 表的 php。出于这个原因,我正在使用间隔,或者它会在每次鼠标移动时都正确?那将加载服务器。

http://jsbin.com/uleza5进行测试,6秒内不要移动鼠标,然后看到空闲文本,然后移动鼠标,它会开始计数;6 秒后,它会在不活动时再次空闲。
