js倒计时显示
脚本说明:把如下代码加入<body>区域中<SCRIPT LANGUAGE="JavaScript"><!-- Begin// Take user here after session timed outtimedouturl = "http://www.k688.com";function Minutes(data) {for (var i = 0; i < data.length; i++)if (data.substring(i, i + 1) == ":")break;return (data.substring(0, i));}function Seconds(data) {for (var i = 0; i < data.length; i++)if (data.substring(i, i + 1) == ":")break;return (data.substring(i + 1, data.length));}function Display(min, sec) {var disp;if (min <= 9) disp = " 0";else disp = " ";disp += min + ":";if (sec <= 9) disp += "0" + sec;else disp += sec; return (disp);}function Down() { sec--; if (sec == -1) { sec = 59; min--; }document.timerform.clock.value = Display(min, sec);window.status = "Session will time out in: " + Display(min, sec);if (min == 0 && sec == 0) {alert("Your session has timed out.");window.location.href = timedouturl;}else down = setTimeout("Down()", 1000);}function timeIt() {min = 1 * Minutes(document.timerform.clock.value);sec = 0 + Seconds(document.timerform.clock.value);Down();}// End --></script><center><form name="timerform"><input type="text" name="clock" size="7" value="2:00"></form></center>第二步：把<body>区域中的内容改为<body bgcolor="#fef4d9" OnLoad="timeIt()"><a href="http://www.alixixi.com/Dev/HTML/jsrun/">欢迎访问阿里西西网页特效集</a>
