1,首先建一个截止日期的字段,截止日期输入表单替换html代码为:<input name="字段" id=jztime onkeyup="字段.value=字段.value.replace(/\,/g,',').replace(/\ /g,',');" type="text" size="" value="<?=stripSlashes($r[字段])?>">
主要是配合下面的js代码,方便后台输入,空格和中文都可自动换为“,”,这种方法也可用到关键词字段
2,列表页加上倒计时JS代码:
<SCRIPT type="text/javascript">
<!--
var target=[]
var time_id=[]
function show_date_time_0(){
setTimeout("show_date_time_0()", 1000);
for (var i=0,j=target.length;i<j;i++){
today=new Date();
timeold=target[i]-today.getTime();
sectimeold=timeold/1000;
secondsold=Math.floor(sectimeold);
msPerDay=24*60*60*1000;
e_daysold=timeold/msPerDay;
daysold=Math.floor(e_daysold);
e_hrsold=(e_daysold-daysold)*24;
hrsold=Math.floor(e_hrsold);
e_minsold=(e_hrsold-hrsold)*60;
minsold=Math.floor((e_hrsold-hrsold)*60);
seconds=Math.floor((e_minsold-minsold)*60);
if (daysold<0) {
document.getElementById(time_id[i])[xss_clean]="到期提示文字或者图片";
}
else {
if (daysold<10) {daysold="0"+daysold}
if (daysold<100) {daysold="0"+daysold}
if (hrsold<10) {hrsold="0"+hrsold}
if (minsold<10) {minsold="0"+minsold}
if (seconds<10) {seconds="0"+seconds}
if (daysold<3) {
document.getElementById(time_id[i])[xss_clean]="<font color=red>"+daysold+"天"+hrsold+"小时"+minsold+"分"+seconds+"秒</font>";
}
else {
document.getElementById(time_id[i])[xss_clean]=daysold+"天"+hrsold+"小时"+minsold+"分"+seconds+"秒";
}
}
}
}
setTimeout("show_date_time_0()", 100);
//-->
</SCRIPT>
3,出现剩余天数的地方显示:<div id="TimeCounter_0" style="border:1px solid black;margin:5px;padding:2px;width:140px"></div>
<SCRIPT>
//设定目标时间(数组元素)
//target[target.length]=new Date(年,月-1,日,时,分,秒).getTime()
target[target.length]=new Date(2010,04,01,00,00,00).getTime();
//设定倒计时显示地址(数组元素)
time_id[time_id.length]="TimeCounter_0"
</SCRIPT>
例子:<li class="ynl2">[!--class.name--]</li>
<li class="ynl3"><a title="[!--oldtitle--] "
href="[!--titleurl--]"
target="_blank" class="yl_06c">
[!--title--]
</a></li>
<li class="ynl4">
<div id="TimeCounter_[!--id--]"></div>
<SCRIPT>
target[target.length]=new Date([!--jztime--]).getTime();
time_id[time_id.length]="TimeCounter_[!--id--]"
</SCRIPT>
</li>
也可用到内容页上,这里显示的是年,月-1,日,时,分,秒,只想显示月和日期的把JS代码里相应值去掉即可:innerHTML=daysold+"天"+hrsold+"小时"+minsold+"分"+seconds+"秒
