var count=0 //删除定时器计时从0秒开始
function getdate() {
var date = new Date(); //获取当时时间
var hour = date.getHours(); //获取当时小时
if(hour<10){ //小于10小时是前面＋0
hour="0"+hour;
}
var min = date.getMinutes();
if(min<10){
min="0"+min;
}
var sec = date.getSeconds();
if(sec<10){
sec="0"+sec;
}
count++;
if(count==20){ //设置20s后定时器暂停
clearInterval(ding)
}
var str = hour + ":" + min + ":" + sec; //字符串拼接
document.getElementById("dd").innerHTML = str; //将时间写到桌面上;
}
var ding=setInterval(getdate,1000); //定时器1s显示一次;
欢迎各位大神指点和评论;
