本来要做个倒计时的，结果网上的一搜一大堆，也不知道是谁抄谁的，反正都一样的错误。   一行一行找，找到一个 document.getElementByIdx_x(“leftTime”+key) 【x_x】是啥！？！？  感觉像是考验开发者 的…我擦~  这代码写的，惊天地泣鬼神啊，尽然这样开玩笑     附：修改正确可以运行的操作方法（图片自己换）   1.打开include/lib_goods.php文件 在  获得促销商品 function get_promote_goods($cats = ”) { 的下面找到 $goods[$idx][‘url’]          = build_uri(‘goods’, array(‘gid’ => $row[‘goods_id’]), $row[‘goods_name’]); 在他的下面添加         $time = gmtime();         if ($time >= $row[‘promote_start_date’] && $time <= $row[‘promote_end_date’])         {              $goods[$idx][‘gmt_end_time’]  = local_date(‘M d, Y H:i:s’,$row[‘promote_end_date’]);         }         else         {             $goods[$idx][‘gmt_end_time’] = 0;         } 2.打开模板文件recommend_promotion.lbi 添加 <meta http-equiv=”Content-Type” content=”text/html; charset=utf-8″> <!– {if $promotion_goods} –> <script > var Tday = new Array(); var daysms = 24 * 60 * 60 * 1000 var hoursms = 60 * 60 * 1000 var Secondms = 60 * 1000 var microsecond = 1000 var DifferHour = -1 var DifferMinute = -1 var DifferSecond = -1 function clock(key) {   var time = new Date()   var hour = time.getHours()   var minute = time.getMinutes()   var second = time.getSeconds()   var timevalue = “”+((hour > 12) ? hour-12:hour)   timevalue +=((minute < 10) ? “:0″:”:”)+minute   timevalue +=((second < 10) ? “:0″:”:”)+second   timevalue +=((hour >12 ) ? ” PM”:” AM”)   var convertHour = DifferHour   var convertMinute = DifferMinute   var convertSecond = DifferSecond   var Diffms = Tday[key].getTime() – time.getTime()   DifferHour = Math.floor(Diffms / daysms)   Diffms -= DifferHour * daysms   DifferMinute = Math.floor(Diffms / hoursms)   Diffms -= DifferMinute * hoursms   DifferSecond = Math.floor(Diffms / Secondms)   Diffms -= DifferSecond * Secondms   var dSecs = Math.floor(Diffms / microsecond)     if(convertHour != DifferHour) a=”<font color=red>”+DifferHour+”</font>天”;   if(convertMinute != DifferMinute) b=”<font color=red>”+DifferMinute+”</font>时”;   if(convertSecond != DifferSecond) c=”<font color=red>”+DifferSecond+”</font>分”     d=”<font color=red>”+dSecs+”</font>秒”     if (DifferHour>0) {a=a}     else {a=”}   document.getElementById(“leftTime”+key).innerHTML =”<img src=’images/clar.gif’ />&nbsp;&nbsp;剩余：”+ a + b + c + d; //显示倒计时信息 } </script> <div id=”sales” class=”f_l clearfix”>       <div class=”clearfix goodBox”>         <!–{foreach from=$promotion_goods key=key item=goods name=”promotion_foreach”}–>         {if $smarty.foreach.promotion_foreach.index <= 4}           <div class=”goodList”> <font class=”f40″ id=”leftTime{$key}”>{$lang.please_waiting}</font>           <a href=”{$goods.url}”><img src=”{$goods.thumb}” border=”0″ alt=”{$goods.name|escape:html}”/></a><br /> <font style=”color:#CCCCCC; font-size:12px;”>{$goods.shop_price}</font> <font class=”f10″>{$goods.promote_price}</font> <a href=”{$goods.url}” target=”_blank”><img src=”images/qg.gif”></a>           </div>         {/if} <script> Tday[{$key}] = new Date(“{$goods.gmt_end_time}”);   window.setInterval(function()     {clock({$key});}, 1000);     </script>         <!–{/foreach}–>       </div>      </div> <!– {/if} –>
