显示特定div下方内容的问题

你好专家 我正在编写一个社交网站，并且在显示名为interactContainers的特定div下面的内容时遇到问题。这个div下面没有任何内容。

css：

.interactContainers
{
    margin-left:10px;
    position:relative;
    width:486px;    
    display:none;
    color: #09F;
    font-weight: bold;
    text-decoration: none;
    vertical-align:middle;
    font-size: 12px;    
    background-color:#222;
    border:#FFF 1px solid;  
}

.interactionLinksDiv a
{
    background-color:#222;
    display:inline;
    border:#FFF 1px solid;
    padding:7px;
    color:#9F3;
    font-size:12px;
    text-decoration:none;
}

以下是pals.php的代码，它允许用户添加或拒绝朋友请求。 在这个切换div下面，我希望能够显示现有用户的好友缩略图，姓名等。

代码：

<?php
//Establish the Web Intersect Profile Interaction Token here
if(!isset($_SESSION['wipit']))//Check to see if session wipit is set yet
{
    session_register('wipit');//Be sure to register the session if it is not yet set
}
$thisRandNum = rand(9999999999999,999999999999999999);
$_SESSION['wipit'] = base64_encode($thisRandNum);
?>
<script type="text/javascript" charset="utf-8">

    }else
    {
        $('#'+x).hide();
    }
    $('.interactContainers').hide();
}

    });
}

    $.post(palRequestURL,{ request: "denyPal", reqID: x, thisWipit: thisRandNum } ,function(data) {

可能是什么问题？即，最后一个被回显的表（在下面）将不会显示。 提前致谢

答案 0 :(得分：0)

我的愚蠢错误。问题是exit（）;在

if($pal_request_num_rows < 1)
{
    echo '&nbsp;You have no Pal requests at this time.';
    exit();
}

不应该在那里
