實操:商品列表三級分類的實現方法

() index absolut query isp 全部 shelf display deb

對於分類來說,一般包括一級分類,二級分類,三級分類,一般2級分類是比較好做的,大部分網站都是左邊點擊二級分類,右邊顯示相對應商品,這就要用到jquery技術了。下面就來為大家詳細分析一下該如何實現吧。

  首先把二級分類給全部遍歷出來,Html代碼如下:
<volist name=‘cate‘ id=‘vo‘>
<li <if condition="$Think.get.name eq $vo[‘name‘]">class="active"</if> onclick="funbrand(‘{$vo.name}‘,‘{$vo.id}‘)" ">

<span style="font-weight: 600;font-size: 13px;height: 45px; display: flex;justify-content: center;align-items: center;padding: 0;border-right: 5px solid white;" data="{$vo.id}" name="cateid" title="">{$vo.name}</span>
</li>
</volist>

根據需求添加點擊事件,寫jquery:

jquery代碼如下:
function funbrand(id,obj){
debugger;
$(obj).addClass(‘active‘);

$(obj).siblings(‘a‘).removeClass(‘active‘);
cateid=$("span[name=‘cateid‘]").attr(‘data‘);

$(‘.all‘).removeClass(‘active‘);
var test=$(‘.all‘).attr(‘title‘); 
var goodscateid = id;
 cate_id=$("input[name=‘cateid1‘]").val();
$(‘#id‘).val(goodscateid);
var types = $(‘#type‘).val();
$.ajax({
    url:"{:U(‘Mobile/goods1‘)}",
    data:{goodscateid:goodscateid,types:types,cate_id:cate_id},
    dataType:"json",
    type:"post",
    success:function(data){
        alert(data.v);
        str = ‘‘;
        $(‘.good_list‘).empty();
        if (data.status==1) {

            $.each(data.shops,function(index,obj){

             str+=‘<dl class="clearfix">‘;

             if(test==‘套餐‘){
                 str+=‘<dt class="col-sm-5 col-xs-5"  style="text-align: center;margin-bottom:25px;margin-top:25px">‘;
                 str+=‘<a style="color:#000;width:200px;overflow:hidden;" href="{:U("Mobile/good_detail")}?gid=‘+obj.gid+‘">‘;

            } 

            if (obj.quota!=‘0‘) {
                    str+=‘ <span style="border: 1px solid #c63731; padding:2px; color:#c63731;border-radius: 8px; font-size: 10px;">‘

                     })
            $(‘.good_list‘).append(str);
            $(‘.good_list‘).html(str).ready(function(){

                 $(".addcar").click(function(){
                 // debugger;
                var uid = $(‘#uid‘).val();
                var gid = $(this).attr(‘title‘);

                if (uid==‘‘) {
                    alert(‘請先登陸‘);
                    location="{:U(‘Mobile/login‘)}";
                    return false;
                }

                 $.ajax({
                    url:"{:U(‘Mobile/goods_info‘)}",
                    data:{gid:gid},
                    dataType:"json",
                    type:"post",

                     success:function(data){
                      // alert(data);
                        // alert(data.thumb);
                         // $(".img").src(‘/Public/Admin/kindeditor-4.1.10/attached/image‘+data.thumb);
                        var thumb=data.thumb;
                        var tep=‘/Public/Admin/kindeditor-4.1.10/attached/image‘+thumb;
                          $("#shopping_img").attr(‘src‘, src=tep) ;
                          $(‘.mo_shopping_quota‘).text(data.quota);
                          $(‘.mo_shopping_gid‘).text(data.gid);
                         $(".title").text(data.gname);
                         $(".shopping_gui").text(data.norms+‘/‘+data.unity);
                         $(‘.shopping_money‘).text(data.price);
                         $(‘.shelflife‘).text(data.shelflife);
                         $(‘.mo_shopping_gid‘).text(data.gid); 
                        $(‘.mo_shopping_addnum‘).text(data.addnum);
                          $(".mo_shopping").css("display","block");
                          $(‘.num‘).val(data.addnum);
                         }
                     })

                 })

             });
         }
     },
 })

}

Php查詢並輸出,代碼如下:
public function goods1(){
$goodscateid=I(‘goodscateid‘);
$cate_id=I(‘cate_id‘);
$where[‘brandid‘]=array(‘exp‘,"regexp ‘(,|^)" .‘$cate_id‘."(,|$)‘");
// $where[‘bid‘]=$goodscateid;
// $info=M("brandlist")->where("bid=$goodscateid")->find();
$info=M("brandlist")->where($where)->select();
foreach ($info as $key => $value) {
$bname=$value[‘bname‘];
$shops[] = M(‘goodsinfo‘)->where("brandlist=‘$bname‘")->order("gid desc")->find();
}

 foreach ($shops as $key => $value) {
      $pic=explode(",",substr($value[‘thumb‘],1,strlen($value[‘thumb‘])));
      $shops[$key][‘thumb‘]=$pic[0];
}
if ($shops) {
      $returnValue[‘status‘]=1;
      $returnValue[‘shops‘]=$shops;

    }else{
  $returnValue[‘status‘]=2;

    }
$this->ajaxReturn($returnValue);

}
