Ajax: The value returned in the background echoes to the page, but the front end does not take these values!

This is the header information sent.

This is the response data

This is the data printed on the background page.

The last code to post in the background:

if($_POST['idp']){           //如果地址栏中有idp，则通过idp获取产品信息；否则根据当前时间获取(取最近有的数据)    $idp = $_POST['idp'];    $sql = "SELECT * FROM `product` WHERE id={$idp}";}else{                       //如果没有idp ,则获取最近期的产品信息    $sql = "SELECT * FROM `product` ORDER BY time DESC LIMIT 1"; }//定义常量$result = array();            $commentData = array();//读取产品的详细信息$productRes = mysql_query($sql, $connect);$productData = mysql_fetch_array($productRes, MYSQL_ASSOC);  //产品详情和相应评论的结果集array_push($result, $productData, $commentData);//array_shift($result);echo json_encode($result);?>

The JSON returned by accessing roamguid.sinaapp.com/page/detail/getdetail.php is GET , executing the $sql = "SELECT * FROM product ORDER BY time DESC LIMIT 1";
