基于ecshop的移动端 etouch实现动态获取分类商品列表

关键两个地方需要修改

if ($_GET['act'] == 'asynclist') {
        $sayList = array();
        if (is_array($goodslist)) {
            foreach ($goodslist as $vo) {
                $shop_price = empty($vo['promote_price']) ? $vo['shop_price']:$vo['promote_price'];
                $watermark_img = empty($vo['watermark_img']) ? '':'.$vo['goods_name'].'" />';
               /* $sayList[] = array(
                    'pro-inner' => '
        
  .$vo['goods_name'].'">  
        

          
 '.$vo['name'].' 
          

          

            '. $shop_price .' 
          
          
 '.$vo['market_price'].'
          
月销:'.$vo['sales_count'].'
          
'.$watermark_img.'
        
'
                );*/
                $collectStr = '';
                if($vo['collect']){
                    //如果已经搜藏了那么
                    $collectStr = '$vo['goods_id'].')">';
                }else{
                    //如果没有搜藏那么
                    $collectStr = '$vo['goods_id'].')">';
                }
                $sayList[] = array(
                 'pro-inner'=>'
                     
                        .$vo['goods_name'].'">
                    
                    

                        
                            '.$vo['name'].'
                        
                        

                            '. $shop_price .'
                        
                        

                            月销:'.$vo['sales_count'].'
                        
                    
                    '.$collectStr.'
                    

                         
                         
                         
                    
                 '
                );
            }
        }
        echo json_encode($sayList);
        exit;
    }

还有一个叫做 category_get_goods 这个函数此函数新增了一个字段 collect返回字段可以用于前端页面视图渲染的时候实现判断是否已经搜藏 并且根据是否搜藏显示不同的样式和绑定不同的事件函数

/**
 * 获得分类下的商品
 *
 * @access  public

 * @return  array

            "g.is_delete = 0 AND ($children OR " . get_extension_goods($children) . ')';

    if ($brand > 0)
    {
        $where .=  "AND g.brand_id=$brand ";
    }

    if ($min > 0)
    {
        $where .= " AND g.shop_price >= $min ";
    }

    if ($max > 0)
    {
        $where .= " AND g.shop_price <= $max ";
    }

    /* 获得商品列表 */$sql = 'SELECT g.goods_id, g.goods_name, g.goods_name_style, g.market_price, g.is_new, g.is_best, g.is_hot, g.shop_price AS org_price, ' .

客户端js代码参考

/* *

 * 添加商品到收藏夹

 */var _current_collect = null;
var _current_goodsId = 0;

functioncollect(_this,goodsId)
{
  _current_collect = _this;
  _current_goodsId = goodsId;
  jQuery.get('user.php?act=collect',{id:goodsId},collectResponse,"JSON");
}

functionuncollect(_this,goodsId)
{
  _current_collect = _this;
  _current_goodsId = goodsId;
  jQuery.get('user.php?act=uncollect',{id:goodsId},collectResponse,"JSON");
}


/* *

 * 处理收藏商品的反馈信息

 */functioncollectResponse(result)
{if(parseInt(result.error) === 0){
         _current_collect.className = '';
         _current_collect.className ="ycd-font-icon uncollect";
         _current_collect.setAttribute('onclick',"uncollect(this,"+_current_goodsId+")");
         _current_collect.innerHTML = '';
     }
     if(parseInt(result.error) === 3){

         _current_collect.className = '';
         _current_collect.className ="ycd-font-icon collect";
         _current_collect.setAttribute('onclick',"collect(this,"+_current_goodsId+")");
         _current_collect.innerHTML = '';
     }
    //这里加入成功//注意这里引入了一个自己写的基于zepto移动端函数库的一个插件 请参考我以前写的一篇文章里面有这个插件的代码
    Zepto('body').popup({
            title:'提示信息'
            ,id:'alert'
            ,closeOnOk:true
            ,ok:'确定',
            message:result.message
        }); 

}

总结

以前非常喜欢php 弄过一段时间 所以php代码也是基本上都能够看懂 mysql 也学过
没有php 基础的童鞋可以先去学学php基础
现在博主努力专研前端 后端也在学习 最近学习javascript 和 html5的新api 这些
记录下自己的工作
