可限制每个人对一个内容的点赞数次,比如以下是规定3次.超过三次会限制的哟

注意,模板中必须引入cookie相关的js,即.通过cookie记住是否顶过.

因为这句,所以需要引入jq,当然也可以直接用原生js的  <script src="\{dede:global.cfg\_templets\_skin/\}/js/jquery.min.js"></script>

$('\#digg'+oldaid\_arr\[0\]).addClass("icon-heart-on");

以下为模板

![70][]

{dede:arclist row='6' orderby='id' titlelen='100'}
    
     <span  id="diggNum[field:id/]"> <a href="javascript:"class=" text-bbb text-16" onclick="javascript:postDigg('good',[field:id/])"><span id="digg[field:id/]" class="icon-heart2 ">     </span> </a>[field:goodpost/] 
    </span>  
    {/dede:arclist}

css

.icon-heart2{
        background: url(../images/bg-main.png) -22px 5px no-repeat;
    }
    .icon-heart2:hover{
        background: url(../images/bg-main.png) 2px 4px no-repeat;
    }
    .icon-heart-on{
        background: url(../images/bg-main.png) 2px 4px no-repeat;
    }

然后在,plus中新建立一个digg\_ajax\_list.php文件,内容为

<?php   
       
    require_once(dirname(__FILE__)."/../include/common.inc.php");   
      
    $action = isset($action) ? trim($action) : '';   
    $id = empty($id)? 0 : intval(preg_replace("/[^\d]/",'', $id));   
      
    if($id < 1)   
    {   
        exit();   
    }   
    $maintable = '#@__archives';   
    if($action == 'good')   
    {   
        $dsql->ExecuteNoneQuery("Update `$maintable` set scores = scores + {$cfg_caicai_add},goodpost=goodpost+1,lastpost=".time()." where id='$id'");   
    }   
    else if($action=='bad')   
    {   
        $dsql->ExecuteNoneQuery("Update `$maintable` set scores = scores - {$cfg_caicai_sub},badpost=badpost+1,lastpost=".time()." where id='$id'");   
    }   
    $digg = '';   
    $row = $dsql->GetOne("Select goodpost,badpost,scores From `$maintable` where id='$id' ");   
    if(!is_array($row))   
    {   
        exit();   
    }   
    if($row['goodpost']+$row['badpost'] == 0)   
    {   
        $row['goodper'] = $row['badper'] = 0;   
    }   
    else  
    {   
        $row['goodper'] = number_format($row['goodpost']/($row['goodpost']+$row['badpost']),3)*100;   
        $row['badper'] = 100-$row['goodper'];   
    }   
      
    if(empty($formurl)) $formurl = '';   
    if($formurl=='caicai')   
    {  
        if($action == 'good') $digg = $row['goodpost'];   
        if($action == 'bad') $digg  = $row['badpost'];   
    }   
    else  
    {   
        $row['goodper'] = trim(sprintf("%4.2f", $row['goodper']));   
        $row['badper'] = trim(sprintf("%4.2f", $row['badper']));       
        $digg = '<a class=" text-bbb text-16"href="javascript:" onclick="javascript:postDigg(\'good\','.$id.')"><span =id="digg'.$id.'"class="icon-heart-on">     </span> </a>'.$row['goodpost'];   //点击后,如果从没有被赞过,则自动把新的点击次数重写入目标位置.
    }   
    AjaxHead();   
    echo $digg;   
    exit();   
    ?>
