css超出部分隐藏,js倒计时

css实现超出部分显示省略号 display: -webkit-box; -webkit-box-orient: vertical; -webkit-line-clamp: 3;//行数 overflow: hidden;

var time = document.getElementById('time'); setInterval(function(){ //获取当前时间 var d1 = new Date(); var d2=new Date(2018,3,23,19,0,0,0);//设置的截止时期，月份要减1 var dis = d2 - d1; var s = Math.round(dis/1000 % 60); var m = Math.floor(dis/1000/60%60); var h = Math.floor(dis/1000/60/60%24); var d = Math.floor(dis/1000/60/60/24); var str = d + "天" + h + "小时" + m + "分钟" + s +"秒"; time.innerHTML = str; },1000);
