例如添加一件商品后,某个div显示当前的商品数量
<div class="pay"> <div class="pay-opt"> <a href="home2.html"><span class="am-icon-home am-icon-fw">首页</span></a> <a><span class="am-icon-heart am-icon-fw">收藏</span></a> </div> <li> <div class="clearfix tb-btn tb-btn-buy theme-login"> <a id="LikBuy" title="点此按钮到下一步确认购买信息" href="#">立即购买</a> </div> <div id="test1"></div> </li> <li> <div class="clearfix tb-btn tb-btn-basket theme-login"> <a id="LikBasket" title="加入购物车" href="javascript:addCart({$rst[0]['g_id']})" onClick="showSum()"><i></i>加入购物车</a> </div> </li> </div> </div> <div class="clear"></div> </div> {literal} <script type="text/javascript"> function showSum(){ var url = "countShopcartid.php"; var data = {"not":""}; var success= function(response){ if(response.errno == 0){ var sum = response.sum; alert(sum); $("#test1").html(sum); }else { alert('获取购物车商品数量失败'); } } $.post(url,data,success,"json"); } </script>{/literal}
countShopcartid.php <?php require_once('include.php'); //1.接受参数并处理 $user_id = $_SESSION["id"]; //2.计算数量 $sql = "select count(*) from shopcar where user_id='{$user_id}'"; $row = $admindb->ExecSQL($sql,$conn); var_dump($row); //3.返回处理结果 if($row){ $response = array( 'errno' =>0, 'errmsg' =>'success', 'data' => true, 'sum' => $row[0]["count(*)"], ); } else{ $response = array( 'errno' =>-1, 'errmsg' =>'fail', 'data' => false, 'sum' => $row[0]["count(*)"], ); } echo json_encode($response); ?>
f12看到sum有值
{"errno":0,"errmsg":"success","data":true,"sum":"2"}
就是传不到test1这个div里
