本文實(shí)例為大家分享了jquery倒計(jì)時(shí)功能的實(shí)現(xiàn)代碼，供大家參考，具體內(nèi)容如下
定義和用法：
setInterval() 方法可按照指定的周期（以毫秒計(jì)）來調(diào)用函數(shù)或計(jì)算表達(dá)式。
setInterval() 方法會(huì)不停地調(diào)用函數(shù)，直到 clearInterval() 被調(diào)用或窗口被關(guān)閉。由 setInterval() 返回的 ID 值可用作 clearInterval() 方法的參數(shù)。
下面舉例
<html> <head> <meta charset="utf-8"> <title>jquery簡單倒計(jì)時(shí)</title> </style> <script type="text/javascript" src="js/jquery.min.js"></script> <script type="text/javascript"> var intDiff = parseInt(60);//倒計(jì)時(shí)總秒數(shù)量 function timer(intDiff) { window.setInterval(function() { var day = 0, hour = 0, minute = 0, second = 0;//時(shí)間默認(rèn)值 if (intDiff > 0) { day = Math.floor(intDiff / (60 * 60 * 24)); hour = Math.floor(intDiff / (60 * 60)) - (day * 24); minute = Math.floor(intDiff / 60) - (day * 24 * 60) - (hour * 60); second = Math.floor(intDiff) - (day * 24 * 60 * 60) - (hour * 60 * 60) - (minute * 60); } if (minute <= 9) minute = '0' + minute; if (second <= 9) second = '0' + second; $('#day_show').html(day + "天"); $('#hour_show').html('<s id="h"></s>' + hour + '時(shí)'); $('#minute_show').html('<s></s>' + minute + '分'); $('#second_show').html('<s></s>' + second + '秒'); intDiff--; }, 1000); } $(function() { timer(intDiff); }); </script> </head> <body> <h1>網(wǎng)頁上的倒計(jì)時(shí)</h1> <div class="time-item"> <span id="day_show">0天</span> <strong id="hour_show">0時(shí)</strong> <strong id="minute_show">0分</strong> <strong id="second_show">0秒</strong> </div> <!--倒計(jì)時(shí)模塊--> </body></html>希望本文所述對(duì)大家學(xué)習(xí)jquery程序設(shè)計(jì)有所幫助。
