<script language="javascript" type="text/javascript">  function postDigg(ftype,aid)   {    var taget_obj = document.getElementById('diggNum'+aid);           var saveid = GetCookie('diggid');   //我所有赞过的文章id    //alert(saveid);    if(saveid != null)       {        var saveids = saveid.split(',');           var hasid = false;           saveid = '';           j = 1;           for(i=saveids.length-1;i>=0;i--)           {            if(saveids[i]==aid && hasid) continue; //我顶过              else {                   if(saveids[i]==aid && !hasid) hasid = true;                   saveid += (saveid=='' ? saveids[i] : ','+saveids[i]);                   j++;                   if(j==20 && hasid) break;                   if(j==19 && !hasid) break;               }           }           if(hasid) {        //alert("您已经顶过该帖，请不要重复顶帖 ！");        //如果点击后,被赞过.则不需要更新统计,直接改变颜色        $('#digg'+aid).addClass("icon-heart-on");        return;         }           else saveid += ','+aid;           SetCookie('diggid',saveid,1);              }       else       {   //如果cookie中无记录,则记录        SetCookie('diggid',aid,1);             }       myajax = new DedeAjax(taget_obj,false,false,'','','');       var url = "{dede:global.cfg_phpurl/}/digg_ajax_list.php?action="+ftype+"&id="+aid;       myajax.SendGet2(url);         DedeXHTTP = null;  }   </script>

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
