计算提交时间到当前时间的距离

[javascript]代码库

function computeTime(replyTime){
	var nowTime = Date.parse(new Date());//获取当前unix时间戳
	var tempTime = nowTime - replyTime;
	var stepflag = Math.round(tempTime/(1000*60));//相差N分钟
	var result;
	if(stepflag < 3)
       result = "刚刚";
    else if(stepflag >= 3 && stepflag < 60)
   	   result = stepflag + "分钟前";
   	else if(stepflag >= 60 && stepflag < 1440)
   	   result = Math.round(stepflag/60) + "小时前";
    else if(stepflag >= 1440 && stepflag < 43200)
       result = Math.round(stepflag/(60*24))+ "天前";
    else
	   result = Math.round(stepflag/(60*24*30))+ "月前";

	return result;
