查看帝国cms建站程序新闻系统的内容页模版代码，找到顶一下的HTML代码块，如下所示：
<table border="0" align="center" cellpadding="0" cellspacing="0" class="digg">
<tr>
<td class="diggnum" id="diggnum"><strong><script type="text/javascript" src="[!--news.url--]e/public/ViewClick/?classid=[!--classid--]&id=[!--id--]&down=5"></script></strong></td>
</tr>
<tr>
<td class="diggit"><a href="JavaScript:makeRequest('[!--news.url--]e/public/digg/?classid=[!--classid--]&id=[!--id--]&dotop=1&doajax=1&ajaxarea=diggnum','EchoReturnedText','GET','');" rel="external nofollow" >来顶一下</a></td>
</tr>
</table>
由以上代码可知，当前的总顶数是通过动态脚本载入的方式实时输出，而a标签上的makeRequest()函数就是用来实现顶一下功能的方法。makeRequest()函数的第一个参数是请求地址并附带参数数据，第二个参数是成功请求后执行的回调函数名，第三个参数指定以GET方式发送请求。了解实现的原理之后就很容易在网站其他页面上实现顶一下(点赞)功能，以下给出实现方法的相关代码。
例如我们需要在产品列表模板页面上实现顶一下功能，那么首先就需要修改产品列表模板的代码，以下是我修改后的列表模板代码：
页面模板内容
<!DOCTYPE html>
<html lang="zh">
<head>
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<meta charset="utf-8">
<title><?php echo ReturnClassAddField(0,"seotitle");?></title>
<meta name="keywords" content="[!--pagekey--]">
<meta name="description" content="[!--pagedes--]">
<link rel="stylesheet" href="[!--news.url--]index/css/style.css" rel="external nofollow" >
</head>
<body>
<div class="head_about">[!--temp.header--]</div>
<div class="bannProOuter"><div class="bannPro"><ul><li><a class="current" href="<?=sys_ReturnBqClassname($class_r[1],9)?>" rel="external nofollow" ><?=$class_r[1][classname]?></a></li></ul></div></div>
<div class="proOuter"><div class="proInner clearfix">
<div class="proSort">
<ul>
[e:loop={"select classid,classname,classpath from phome_enewsclass where classid in (7,8,9,10,11) order by classid asc",0,24,0}]
<?php
if($bqno==5){
echo '<li class="lastChild">';
}else{
echo "<li>";
}
$titleclass="";
if($bqr[classid]==$GLOBALS[navclassid]){
$titleclass="current";
}
?>
<a href="<?=$bqsr[classurl]?>" rel="external nofollow" class="<?=$titleclass?>"><?=$bqr[classname]?></a></li>
[/e:loop]
</ul>
</div>
<div class="selectNumberScreen"><div class="screenBox"><?=user_ShowFieldandChange()?></div></div>
<div class="proList clearfix"><ul>[!--empirenews.listtemp--]<!--list.var1-->[!--empirenews.listtemp--]</ul></div>
<div class="page2 txtC">[!--show.listpage--]</div>
</div></div>
[!--temp.footer--]
<script type="text/javascript">
$(".proList .photo").hover(function(){$(this).find(".txt").stop().animate({height:"300px"},300);},function(){$(this).find(".txt").stop().animate({height:"0px"},300);});
</script>
</body>
</html>
列表内容模板(list.var)
$nomar="";
if($no%4==0){$nomar=" class=\"nomar\"";}else{$nomar="";}
if($r[titlepic]){$tpic=sys_ResizeImg($r[titlepic],300,300,1,"");}else{$tpic="/e/data/images/notimg.gif";}
$listtemp='<li'.$nomar.'><div class="photo"><img src="'.$tpic.'"><a href="[!--titleurl--]" rel="external nofollow" rel="external nofollow" rel="external nofollow" ><div class="txt"><h4>查看<br>详情</h4></div></a></div>
<b><a href="[!--titleurl--]" rel="external nofollow" rel="external nofollow" rel="external nofollow" >[!--title--]([!--model--])</a></b>
<a href="[!--titleurl--]" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="icon-thumbs-up" data-classid="[!--classid--]" data-id="[!--id--]"><em>[!--diggtop--]</em>人赞过</a></li>';
最后在底部模板里或JS文件中加入以下js代码，大功告成
[html] view plain copy print?
<script type="text/javascript">
$(".icon-thumbs-up").click(function(event){
event.preventDefault();
var mythis = $(this);
var classid = mythis.data("classid");
var id = mythis.data("id");
$.ajax({
type:"GET",
url:"[!--news.url--]e/public/digg/",
data:{"classid":classid,"id":id,"dotop":1,"doajax":1,"ajaxarea":"diggnum"},
dataType:"text",
success:function(data){
var reinfo = data.split("|");
if (reinfo.length != 1) {
if (reinfo[0] != "") {
mythis.find("em").html(reinfo[0]);
}
if (reinfo[2] != "") {
//var left = parseInt(mythis.offset().left)+20, top = parseInt(mythis.offset().top);
var left = 20, top = mythis.find("em").get(0).offsetHeight;
$(".zan").remove();
if (reinfo[2] == "谢谢您的支持") {
mythis.append('<div class="zan">+1 谢谢您的支持</div>');
//$("body").append('<div class="zan">+1 谢谢您的支持</div>');
}else{
mythis.append('<div class="zan">已赞</div>');
//$("body").append('<div class="zan">已赞</div>');
}
//"text-shadow":"0 1px 0 rgba(0,0,0,0.5)","font-family":"simsun"
$(".zan").css({"position":"absolute","z-index":"10","left":left+"px","top":-top+"px","color":"inherit"}).animate({top:-top-30},"slow",function(){$(this).fadeIn("fast").remove();});
}
}else{}
}
});
});
</script>
