我在访问ajax调用返回的json值时遇到问题。

电话如下：

    $.ajax({
    type: \'POST\',
    data: \'user_id=\' + user.user_id + \'&user_login=\'+ user.user_login,
    //dataType: \'json\',
    url: \'http://###/user-stats.php\',
    success: function(data){
        alert(data);
        //alert(data.games_won[0][\'winner_id\']);
        //console.log(data);
        if(data) {
            $(\'#hand-stats-display\').html(data);
            //$.mobile.changePage( "#user-home", { transition: "fade"} );
        }else{ 
            $(\'.messages\').html("No stats available at this time... Please try again later.");
            //alert(data);
        }

    },
    error: function(){
        //console.log(data);
        alert(\'Ajax Login Request ✗\');
    }
    });

以下是PHP：

$myrows[\'hands_won\'] = $wpdb->get_results( "SELECT * FROM wp_winners WHERE user_id=" . $user_id );


if ( $myrows ) 
{
    //echo(\'Rows Exist ✓\');
    //echo "List of {$meta_key1} posts, sorted by {$meta_key2}";
    foreach ( $myrows as $id ) 
    {
        $creds[]=$id;
        //echo(\'MyRows: \' . $myrows[id]);
    }
}

//echo "Winner ID:" .$myrows[0]->win_id;
//echo "Winner 2 ID:" .$myrows[1]->win_id;



echo json_encode($creds);

它返回一个json对象，如：

[{"win_id":"1","user_id":"1","game_id":"1"},{"win_id":"2","user_id":"1","game_id":"2"}]

我似乎无法使用我正在使用的javascript访问这些内容。如有任何建议，我们将不胜感激。
