JS的秒杀倒计时
代碼?
<!DOCTYPE html> <html> <head><meta charset="UTF-8"><title></title> </head> <body onload="miaosha();"><p class="tit_right" style=""><span id="d" style="">00</span>天<span id="h" style="">00</span>時<span id="m" style="">00</span>分<span id="s" style="">00</span>秒</p></body> </html><script src="https://code.jquery.com/jquery-3.1.1.min.js"></script> <script>var timer = null;// 秒殺函數function miaosha(year, month, day, hour, minute, second) {// 剩余時間：設定的-當前的var leftTime = (new Date(year, month - 1, day, hour, minute, second)) - (new Date());// parseInt()返回一個整數。得出剩余的時分秒var days = parseInt(leftTime / 1000 / 60 / 60 / 24, 10);var hours = parseInt(leftTime / 1000 / 60 / 60 % 24, 10);var minutes = parseInt(leftTime / 1000 / 60 % 60, 10);var seconds = parseInt(leftTime / 1000 % 60, 10);// 結束的時候if (seconds < 0) {alert("快點！");clearTimeout(timer);}else {// 格式的轉化days = fix(days, 2);hours = fix(hours, 2);minutes = fix(minutes, 2);seconds = fix(seconds, 2);// 遞歸調用 注意：比當前時間大！timer = setTimeout("miaosha(2019,04,25,10,56,00)", 1000); 設置開始的時間// 設置時分秒document.getElementById("h").innerHTML = hours;document.getElementById("m").innerHTML = minutes;document.getElementById("s").innerHTML = seconds;document.getElementById("d").innerHTML = days;}}//fix函數：數字加0function fix(num, length) {console.log(num);// 數字轉化為字符串 進行拼接return num.toString().length<length?'0'+num:num;} </script>顯示?
