Javascript 不使用'；我不在野生动物园工作

我有这个脚本，它工作得很好，但是safari和firefox出现了一些问题。 问题是南

应该是：

此部分应存储当前时间

var timediff=(this.targetdate-this.currentTime)/1000 //Differenza tra la data desiderata e quella corrente, in secondi
if (timediff<0){ 
this.timesup=true
this.container.innerHTML=this.formatresults()
return
}
var oneMinute=60 //minuti in secondi
var oneHour=60*60 //ore in secondi
var oneDay=60*60*24 //giorni in secondi
var dayfield=Math.floor(timediff/oneDay)
var hourfield=Math.floor((timediff-dayfield*oneDay)/oneHour)
var minutefield=Math.floor((timediff-dayfield*oneDay-hourfield*oneHour)/oneMinute)
var secondfield=Math.floor((timediff-dayfield*oneDay-hourfield*oneHour-minutefield*oneMinute))
if (this.baseunit=="hours"){ 
hourfield=dayfield*24+hourfield
dayfield="n/a"
}
else if (this.baseunit=="minutes"){ 
minutefield=dayfield*24*60+hourfield*60+minutefield
dayfield=hourfield="n/a"
}
else if (this.baseunit=="seconds"){ 
var secondfield=timediff
dayfield=hourfield=minutefield="n/a"
}
this.container.innerHTML=this.formatresults(dayfield, hourfield, minutefield, secondfield)
setTimeout(function(){thisobj.showresults()}, 1000) //Aggiorna ogni secondo
}

解决方案？

它似乎只适用于chrome。

targetdate的值是多少？如果targetdate的格式无效，则date对象将无效，从有效日期中减去它将导致NaN。targetdate是SQL数据库中倒计时结束的日期。格式为unixtime，如下所示：1451520000我需要转换它？targetdate的值是多少？

targetdate

？如果targetdate格式无效，date对象将无效，从有效日期中减去它将导致NaN。targetdate是SQL数据库中倒计时结束的日期。格式是unixtime，它是这样的：1451520000我需要转换它吗？
