php商品对比功能代码分享_PHP
下面是自己亲自动手编写的代码,和大家一起学习研究。
商品对比调用的JS文件(包含了商品对比框浮动JS):
/*浮动窗口*/ (function(){ var n=10; var obj=document.getElementById("goods-compare"); if(!obj){ return false; } var x=0; window.onscroll=function(){ obj.style.top=(document.body.scrollTop||document.documentElement.scrollTop)+n+'px'; }; window.onresize=function(){ obj.style.top=(document.body.scrollTop||document.documentElement.scrollTop)+n+'px'; }; })(); //添加显示对比框 function addcompare(chk){ $('#goods-compare').fadeIn().show(); var count=$(".compare-box li").length; if (count>2)//这里可以修改对比的数据哦 { alert('产品比较最多选3种哦'); return; } $.ajax({ type: 'post', url: 'ajax.php', data: { 'action':'1', 'gid':chk.gid,//商品ID 'gname':chk.gname,//商品名称 'gtype':chk.gtype//商品类别,类别不同时不能比较 }, cache: false, async: false, success: function(result) { if(result!='') { alert(result); }else{ var url='http://www.lusen.com/product-'+chk.gid+'.html';//设置商品的链接地址 $(".compare-box").append("<li class='division clearfix' id='"+chk.gid+"'><div class='span-3'><a href='"+url+"' target='_blank' title='"+chk.gname+"'>'"+chk.gname+"'</a></div><span onclick=\"removecompare('"+chk.gid+"');\">删除</span></li>") $("#comids").val($(".compare-box li").map(function(){//将对比的所有商品ID,赋值给#comids return $(this).attr('id'); }).get().join(",")); } } }); } //删除对比产品 function removecompare(id) { $.ajax({ type: 'post', url: 'ajax.php', data: { 'action':'2', 'gid':id }, cache: false, success: function(result) { $("#"+id).remove(); $("#comids").val($(".compare-box li").map(function(){ return $(this).attr('id'); }).get().join(",")); } }); } //清空对比产品 function clearcompare() { $.ajax({ type: 'post', url: 'ajax.php', data: { 'action':'3' }, cache: false, success: function(result) { $(".compare-box").html(''); $("#comids").val(''); } }); } //显示对比框 function showcompare() { $.ajax({ type: 'post', url: 'ajax.php', data: { 'action':'4' }, success: function(result) { if(result){ $(".compare-box").append(result); $("#comids").val($(".compare-box li").map(function(){ return $(this).attr('id'); }).get().join(",")); $('#goods-compare').fadeIn().show(); } } }); } //点击关闭对比框 $('.close-gc').click(function(){ $('#goods-compare').fadeOut().hide(); });
商品对比调用Ajax文件
<?php function mb_unserialize($serial_str) { $serial_str =stripslashes($serial_str); return unserialize($serial_str); } if($_POST['action']=='1') {//add if(isset($_COOKIE['gtype'])) { if($_COOKIE['gtype']!=$_POST['gtype']) { echo '对不起,您选择的是不同类别的产品无法加入对比,请选择同类产品或清空当前对比栏再选择。'; return; } }else { setcookie('gtype',$_POST['gtype']); } if(isset($_COOKIE['gid'])) { $arr_str = $_COOKIE['gid']; $arr=mb_unserialize($arr_str); if(count($arr)>2) {//商品比较数量 echo "商品比较最多选3种"; return; } foreach($arr as $val) { if($val[0]==$_POST['gid']) { echo "该商品已经加入对比框"; return; } } $info=array($_POST['gid'],$_POST['gname'],$_POST['gtype']); $arr[]=$info; $arr_str=serialize($arr); setcookie('gid',$arr_str); }else { $info=array($_POST['gid'],$_POST['gname'],$_POST['gtype']); $arr[]=$info; $arr_str=serialize($arr); setcookie('gid',$arr_str); } }else if($_POST['action']=='2') {//delone $id=$_POST['gid']; $arr_str = $_COOKIE['gid']; $arr=mb_unserialize($arr_str); foreach($arr as $key=>$val) { if($val[0]==$id) { unset ($arr[$key]); } } $arr_str=serialize($arr); setcookie('gid',$arr_str); }else if($_POST['action']=='3') {//delall setcookie('gid',''); setcookie('gtype',''); }else if($_POST['action']=='4') {//showlist if(isset($_COOKIE['gid'])) { $data=''; $arr_str = $_COOKIE['gid']; $arr=mb_unserialize($arr_str); foreach ($arr as $val){ $url="http://www.lusen.com/product-".$val[0].".html"; $data.="<li id='{$val[0]}' class='division clearfix'><div class='span-3'><a href='{$url}' target='_blank' title='{$val[1]}'>{$val[1]}</a></div><span onclick=\"removecompare('{$val[0]}');\">删除</span></li>"; } echo $data; } } ?>
以上就是商品对比功能实现代码,希望大家可以仔细研究,有好的想法大家一起探讨。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
