ajax在ecshop上的运用

ajax在 ecshop 上的运用主要分为步骤：

1.编写调用函数：

  function query()
 {
 
    var sn_id = document.getElementById('sn_id').value.replace(/(^\s*)|(\s*$)/g, "");
 if(!have_chinies(sn_id))
      Ajax.call('sn_id.php?sn_id=' + sn_id, '', rep_sn_id, 'GET', 'JSON');
 
 }

 

2.返回前台掉用：

 

<?php   define('IN_ECS', true);

  require(dirname(__FILE__) . '/includes/init.php');   include('includes/cls_json.php');

  $json   = new JSON;   $result = array('goods_name' =>'没有找到任何记录' , 'goods_sn' => '没有找到任何记录');   $sn_id  = !empty($_GET['sn_id'])?$_GET['sn_id']:'';   $sql    = "select goods_name,goods_sn from" . $ecs->table('goods') . "where (goods_id='$sn_id'  or  goods_sn='$sn_id') ";   $res    = $db->getAll($sql);     if(!empty($res))   {     $result['goods_name'] = $res[0]['goods_name'];  $result['goods_sn'] = $res[0]['goods_sn'];     }      die($json->encode($result));

?>

3.执行回调函数：

function rep_sn_id(result) {       document.getElementById('_good_id').innerHTML = '商品名称：' + result.goods_name + "</br>"    document.getElementById('_good_id').innerHTML += '商品编号：' + result.goods_sn + "</br>";

}
