后端代码

<code>$sql=mysql_query("select number,decode from hongbao order by rand() limit 1 ");
$row=mysql_fetch_array($sql);
$_SESSION['ip']=$_POST['ip'];
$data['number']=$row['number'];
$data['decode']=$row['decode'];
echo  json_encode($data);
?></code>

前端代码

<code>$(document).ready(function(){
    $(".red").click(function(){
        $(this).addClass("shake");
        setTimeout(function(){
            $(".red").removeClass("shake");
            $.post(
                  "recive.php",
                        {ip:$("#ip").val()},
                        function(data){
                            $(".windows").fadeIn();
                            $("#number").attr("value",dada.number);
                            $("#decode").attr("value",data.decode);
                            $(".opacity").fadeIn();
                        }
            )
        },2000);
    });
    $(".close").click(function(){$(this).parent().fadeOut();$(".opacity").fadeOut()})
});</code>

返回数据那里是不是写错了,求大神分析···

返回数据那里是不是写错了,求大神分析···

<code>$data=array();
$result=mysql_query("SELECT xx FROM xxoo LIMIT 1");
//把结果放进循环中看看
while($row=mysql_fetch_array($result)){
    array_push($data,array("xx"=>$row['xx']));
    //还是不行可能是json的格式不是标准的
    //以上的标准的json格式
}
echo json_encode($data);</code>

怀疑是你的url写错了,是 recive.php 还是 receive.php ?

$.post少了一个参数,设置为 json
