我想实现的是下图这个功能

目前树结果已经用PHP生成完成（listhou.php)，怎么才能点这个树的A标签不跳转页面传参到另一个PHP页面(listhou2.php)并取回结果呢？
HTML部分代码

回复讨论(解决方案)

是放到

里吗？

$($(".listshow a").click(function() {  $("list2").load($(this).attr("href"));  return false;});

Copy after login

1、加上点击事件 $($(".listshow a").click(function() {
2、在1的处理方法里用ajax调用
3、在listhou2.php页面里接收值，并处理，（可以返回值，也可以没有）

例：

$.ajax({                       type:'get',                      async : false,                      url: "{:U('paygoodsAjax')}",                       data:"ord_id="+ord_id,                                                              success: function(msg){                                              flag= true;                                              //alert(msg)                                              if(msg==1004){                                                  flag= false;                                                  $("#jian").html("商品已下架！")                                                  $("#jian").css("display",'block');                                                  function times(){                                                     $("#jian").css("display",'none');                                                     clearInterval(timer);                                                   }                                                  timer=setInterval(times,2500);                                                                                                 }                                              else if(msg==1003){                                                       flag= false;                                                       $("#jian").html("商品库存不够了")                                                       $("#jian").css("display",'block');                                                       function times(){                                                          $("#jian").css("display",'none');                                                          clearInterval(timer);                                                        }                                                       timer=setInterval(times,2500);                                                                     }else if(msg==1002){                                                      flag= false;                                                       $("#jian").html("订单存在过期促销商品！")                                                       $("#jian").css("display",'block');                                                       function times(){                                                          $("#jian").css("display",'none');                                                          clearInterval(timer);                                                        }                                                       timer=setInterval(times,3000);                                               }                                                                          //location.reload();                      }                  });                               return flag;

后端处理

//ajax 商品支付前判断       public function paygoodsAjax(){           $ord_id=I("get.ord_id");           //echo $ord_id;           $ordershopids=M("ordershop")->where("order_id = '$ord_id'")->getFields("shop_id");           //var_dump($ordershopids);           //判断商品是否下架或者库存为0           if($ordershopids){               foreach($ordershopids as $id){                   $goodsinfo=M("goodsshop")->where("id = '$id'")->find();                   //var_dump(M("goodsshop")->getLastSql());                   if($goodsinfo){                       if($goodsinfo['is_up']!=1){                           echo "1004";exit();                       }                       if($goodsinfo['stock']<=0){                           echo "1003";exit();                       }                   }else{                       echo "1004";exit();                   }               }           }

把这个代码加到页面后直接就一片空白了啊，是这样加吗？

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>测试</title><link rel="stylesheet" type="text/css" href="style/index.css" /><script type="text/javascript" src="js/jquery-1.11.3.min.js"></script><script type="text/javascript"> $(function(){    $(".listshow ul").load("listhou.php");});</script></head><body><div class="listshow" ><ul></ul></div><div class="list2">   </div></body></html>

Copy after login

$(".listshow a").click(function() {
$("list2").load($(this).attr("href"));
return false;
});

列表在 listhou.php 产生，所以要写在
$(".listshow ul").load("listhou.php"); 的回调里
即
$(".listshow ul").load("listhou.php", {}, function() {
$(".listshow a").click(function() {
$("list2").load($(this).attr("href"));
return false;
});
});

$(".listshow a").click(function() {
$("list2").load($(this).attr("href"));
return false;
});

麻烦您再给看看还是不传参数

'.$row1['d_name'].'
又要是这样的超链
userid 传不过去？

<!DOCTYPE html><html lang="en"><head>    <meta charset="UTF-8">    <title>Title</title>    <script type="text/javascript" src="jquery.min.js"></script>    <script>        $(function(){            $('.listshow').load('list.php', function(){                $('.listshow a').on('click', function(){                    $('.list2').load($(this).attr('href'));                    return false;                });            });        })    </script></head><body><div class="listshow"></div><div class="list2"></div></body></html>

楼主的代码的list2前少了一个点，估计加载不出来

OK 谢谢各位，解决了
