我使用一个小脚本来显示自给定日期时间值(从 PHP 查询传递)以来的时间量。
脚本如下:
<script language="JavaScript">
TargetDate = "<?php echo $dti3; ?>";
FinishMessage = "done"
BackColor = "white";
ForeColor = "black";
CountActive = true;
LeadingZero = true;
DisplayFormat = "%%D%% Days %%H%%:%%M%%:%%S%% ";
</script>
<script type="text/javascript" language="JavaScript" src="time.js"></script>
和 time.js 是
function calcage(secs, num1, num2) {
s = ((Math.floor(secs/num1))%num2).toString();
if (LeadingZero && s.length < 2)
s = "0" + s;
return s;
}
function CountBack(secs) {
if (secs < 0) {
document.getElementById("cntdwn").innerHTML = FinishMessage;
return;
}
DisplayStr = DisplayFormat.replace(/%%D%%/g, calcage(secs,86400,100000));
DisplayStr = DisplayStr.replace(/%%H%%/g, calcage(secs,3600,24));
DisplayStr = DisplayStr.replace(/%%M%%/g, calcage(secs,60,60));
DisplayStr = DisplayStr.replace(/%%S%%/g, calcage(secs,1,60));
document.getElementById("cntdwn").innerHTML = DisplayStr;
if (CountActive)
setTimeout("CountBack(" + (secs+CountStepper) + ")", SetTimeOutPeriod);
}
function putspan(backcolor, forecolor) {
document.write("<span id='cntdwn'></span>");
}
if (typeof(BackColor)=="undefined")
BackColor = "white";
if (typeof(ForeColor)=="undefined")
ForeColor= "#2A8827";
if (typeof(TargetDate)=="undefined")
TargetDate = "12/31/2020 05:00:00";
if (typeof(DisplayFormat)=="undefined")
DisplayFormat = "%%D%% days, %%H%% hours, %%M%% minutes, %%S%% seconds.";
if (typeof(CountActive)=="undefined")
CountActive = true;
if (typeof(FinishMessage)=="undefined")
FinishMessage = "no data";
if (typeof(CountStepper)!="number")
CountStepper = +1;
if (typeof(LeadingZero)=="undefined")
LeadingZero = true;
CountStepper = Math.ceil(CountStepper);
if (CountStepper == 0)
CountActive = false;
var SetTimeOutPeriod = (Math.abs(CountStepper)-1)*1000 + 1000;
putspan(BackColor, ForeColor);
var dthen = new Date(TargetDate);
var dnow = new Date();
if(CountStepper>0)
ddiff = new Date(dnow-dthen);
else
ddiff = new Date(dthen-dnow);
gsecs = Math.floor(ddiff.valueOf()/1000);
CountBack(gsecs);
如果少于 24 小时,我想将自 $dti3 以来的时间显示为 %%H%%:%%M%%:%%S%%,否则仅显示带有一些文本的天数。IE:
自日期以来的 23 小时显示为:“23:00:00”,但 25 小时显示为:“超过一天”,49 小时显示为“超过两天”等...
我想这将需要一个 if else 语句,但我不是一个 JS 编码器(但 - 我正在努力!)所以我不确定实现这一目标的最佳方法。
任何帮助将非常感激,
非常感谢。
