我只想在人们不空闲的时候更新用户在线数据库上的时间戳(键盘鼠标活动了一段时间,我正在使用jquery插件)。我的问题是我无法清除函数的间隔,所以在下面的测试脚本中,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,这样它的计数速度会快一倍。我该如何停止计时器?这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。
在实际的脚本中,计数器将是$.get()-更新mysql表的php。出于这个原因,我使用间隔,或者它会影响每一次鼠标移动,对吗?并且这将加载服务器。
http://jsbin.com/uleza5测试只需6秒钟不移动鼠标,然后看到空闲文本,然后移动鼠标,它就会开始计数;6秒钟后,它将在不活动时再次变为空闲。
