逻辑如下:
1、先判断两个时间的时间差,当然如果得到的时间是13位时间戳的话你需要转化一下
2、判断时间够一天显示天数,够一小时显示小时数
相关代码:
//获取时间,时间戳转换,不是则不转var mydate1 = new Date(parseInt(time1.replace("/Date(", "").replace(")/", "")))
var mydate2 = new Date(parseInt(time2.replace("/Date(", "").replace(")/", "")))
//获取剩余秒数
var timerc =dateDiff(mydate, '2015/05/19 10:00:00') / 1000
function dateDiff(date1, date2) {
var dt1 = new Date(Date.parse(date1))
var dt2 = new Date(Date.parse(date2))
try {
return Math.round((dt2.getTime() - dt1.getTime()))
}
catch (e) {
return e.message
}
}
//循环调用倒计时
function add() { //加时函数
--timerc //时间变量自减1
var day = parseInt(timerc / 86400)
var hour = parseInt((timerc % 86400) / 3600)
var min = parseInt((timerc % 3600) / 60)
var sec = Number(parseInt(timerc % 60 / 10)).toString() + Number(parseInt((timerc % 10))).toString()
if (day > 0) { //如果不到5分钟
$("#day").html(day + '天') //写入天数
$("#hour").html(hour + '时') //写入小时数
$("#min").html(min + '分') //写入分钟数
$("#sec").html(sec + '秒') //写入秒数(两位)
}
else if (hour > 0) {
$("#hour").html(hour + '时') //写入小时数
$("#min").html(min + '分') //写入分钟数
$("#sec").html(sec + '秒') //写入秒数(两位)
}
else if (min > 0) {
$("#min").html(min + '分') //写入分钟数
$("#sec").html(sec + '秒') //写入秒数(两位)
}
else if (sec != '00') {
$("#sec").html(sec + '秒') //写入秒数(两位)
}
else {
tiao(activity) return true//时间到0调用函数
}
setTimeout("add()", 1000) //设置1000毫秒以后执行一次本函数
}
望采纳!
function test(){var txt1 = document.getElementById("txt1"),
txt2 = document.getElementById("txt2"),
txt3 = document.getElementById("txt3"),
opt = document.getElementById("sel")
txt3.value = eval(txt1.value + opt.value + txt2.value)//eval函数可计算某个字符串,并执行其中的的js代码
} <input type="text" id="txt1" />
<select id="sel">
<option value="+">+</option>
