1. 60s 倒计时
var clicking;//防止重复点击 function taketime(obj) { var timeInterval; //定时任务 if (clicking) { return; } var number = 60; timeInterval= window.setInterval(function () { if (number <= 0) { obj.html("发送验证码"); window.clearInterval(timeInterval); clicking = false; } else { clicking = true; obj.html(number -= 1).append(" s后重发");//.......每秒内容更改 } }, 1000); }
2. 天数、时、分、秒
//html
<body onload="leftTimer()"> //js
function leftTimer(year,month,day,hour,minute,second){ var leftTime = (new Date(year,month-1,day,hour,minute,second)) - (new Date()); //计算剩余的毫秒数 var days = parseInt(leftTime / 1000 / 60 / 60 / 24 , 10); //计算剩余的天数 var hours = parseInt(leftTime / 1000 / 60 / 60 % 24 , 10); //计算剩余的小时 var minutes = parseInt(leftTime / 1000 / 60 % 60, 10);//计算剩余的分钟 var seconds = parseInt(leftTime / 1000 % 60, 10);//计算剩余的秒数 days = checkTime(days); hours = checkTime(hours); minutes = checkTime(minutes); seconds = checkTime(seconds); setInterval("leftTimer(2016,11,11,11,11,11)",1000); document.getElementById("timer").innerHTML = days+"天" + hours+"小时" + minutes+"分"+seconds+"秒"; } function checkTime(i){ //将0-9的数字前面加上0，例1变为01 if(i<10) { i = "0" + i; } return i; }
