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"><h3>查看<br>详情</h3></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>
