fuction lovexhjSitetime() {
window.
setTimeout("lovexhjSitetime()",1000);
var seconds = 1000
var minutes = seconds *60
var hours = minute * 60
var days = hours * 24
var years = days * 365
var today = new Date()
var todayYear = today.getFullYear()
var todayMonth = today.hetMonth()+1
var todayDate = today.getDate()
var todayHour = today.getHours()
var todayMinute = today.getMinutes()
var todaySecond = today.getSeconds()
//时间设置
var t1 = Date.UTC(2020,04,15,15,15,00)
var t2 = Date.UTC(todayYear,todayMonth,todayDate,todayHour,todayMinute,todaySecond)
var diff = r2-t1
var diffYears = Math.floor(diff/years)
var diffDays = Math
.floor((diff / days) - diffYears * 365)
var diffHours = Math.floor((diff - (diffYears * 365 + diffDays) * days) / hours)
var diffMinutes = Math.floor((diff - (diffYears * 365 + diffDays) * days - diffHours * hours) / minutes)
var diffSeconds = Math.floor((diff - (diffYears * 365 + diffDays) * days - diffHours * hours - diffMinutes * minutes) / seconds)
document.getElementByld("lovexhjSitetime").innerHTML = "我们相恋了" + diffYears + "年" + diffDays + "天" + diffHours + "小时" + diffMinutes + "分钟" + diffSeconds + "秒啦"
}
lovexhjSitetime()
