这是我的代码，现在灯箱正在工作。对话框仅在我们删除灯箱脚本时才有效。谁能建议对话框未加载的可能原因是什么？在 chrome 控制台上它显示 Uncaught TypeError: Cannot call method 'click' of null

<?php
    include 'header.inc.php';
    $floor_id=$_GET['id'];
    $path='floorPlanImages';
    //include 'addImageForPlan.php';
    $select_floor_images=mysql_query("SELECT id,image FROM zb_floorplan_gallery WHERE floor_id='$floor_id'");
    if(mysql_num_rows($select_floor_images)>0)
    {
    ?>

观察你的 DOM 以找出错误。

可能是 jquery 与 lib 的冲突。

尝试写jQuery.noConflict(); 之前： 

$( document ).ready(function().....

并把你的库：

<script type="text/javascript" src="js/prototype.js"></script>
<script type="text/javascript" src="js/scriptaculous.js?load=effects,builder"></script>
<script type="text/javascript" src="js/lightbox.js"></script>

就在调用你的 jquery lib 之后

<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>
