要下班了没时间了，这两个函数能帮到你第一个把时间转换为整数，这样你就能去计算了，第二个把数字转换成时间，你可以用来显示了
function getIntFromTime(time) {
time = time.split(':')
return parseInt(time[0], 10) * 60 * 60 + parseInt(time[1], 10) * 60 + parseInt(time[2], 10)
}
function getTimeFromInt(value) {
var h = Math.floor(value / 60 / 60)
var m = value % (60*60)
var s = value % (60)
if (h.toString().length <2) h = '0' + h.toString()
if (m.toString().length <2) m = '0' + m.toString()
if(s.toString().length <2) s = '0' + s.toString()
return h + ':' + m + ':' + s
}
div上绑定一个hover事件，并开始计时。以jquery为例。
var tid = 0$( "#div" ).hover( function() {
tid = setTimeout( function() {
//当触发hover就开始自动在1秒后执行相应代码
}, 1000 )
}, function() {
clearTimeout( tid )//当在1秒内退出了hover事件就取消计时代码
} )
