jQuery错误"u未定义"； [英] Jquery error "u is undefined"

问题描述

为什么我在Firebug中收到错误消息"u is undefined"?

Why am I getting an error in Firebug "u is undefined"?

我的页面包括显示照片和照片库，这是PHP代码中使用"break"分隔的特殊部分.

My page consists of a display of photos and photo gallery as a special separate section in the PHP code divided using the "break".

使用"Fancybox.js"显示照片和画廊.

Photos and photo galleries are displayed using the "Fancybox.js".

第一次尝试打开照片时，一切正常，但是刷新页面后再次执行时，Firebug显示错误"u is undefined".

The first time when I try to open a photo, everything works fine but when I do it again after I refresh the page the Firebug display error "u is undefined".

我用于菜单的Jquery显示页面的这些单独部分:

The Jquery for the menu that I'm using for display these separate part of the page:

$(document).ready(function(){

$(".menu_rfr").bind('click', function() {
$("#main").html('<img src="img/spin.gif" class="spin">');
location.replace($(this).attr('rel'));

});

$(".menu_clickable").bind('click', function() {
$("#main").html('<img src="img/spin.gif" class="spin">');
$("#main").load($(this).attr('rel'), function(event) {

});        
$(".menu_clickable").unbind("click");

});

});

简化的PHP代码如下:

The simplified PHP code looks like:

<?
if (!isset($a)) $a = '';
switch($a)
{
case 1:
default:
?>
<div class="menu_clickable prof_link" id="prof_info" rel="?a=2">Photos</div>
<div class="menu_clickable prof_link" id="prof_info" rel="?a=3">Gallery</div> 
<div id="main"></div>    
<?
break;//photos
case 2:
?>
<script type="text/javascript"> 

$("a.group").fancybox({
'titlePosition'     : 'over',
'overlayShow':false
 });
 </script>
 <?
 <a href="1.jpg" id="group" class="group"><img src="tmb/1.jpg" border="0"></a>
 <?
 break;
 case 3: // photo gallery 
 ?>
<script type="text/javascript"> 

$("a.groupg").fancybox({
'titlePosition'     : 'over',
'overlayShow':false
 });
 </script>
 <?
 <a href="2.jpg" id="groupg" class="groupg"><img src="tmb/2.jpg" border="0"></a>
 <?
 break;
 }
 ?>

正如我所说的，这是一个简化的代码，可能其中包含一些错误.我只是想展示我在哪里以及如何使用Fancybox.

As I said this is a simplified code, and probably there are some errors in it. I just wanted to show where and how I'm using Fancybox.

页面顶部菜单的jquery代码与fancybox的jquery代码之间是否存在冲突，或者有其他一些原因导致我在打开另一部分后在Firebug中仍然出现错误"u is undefined" PHP页面并尝试重新打开照片?

Is there a conflict between the jquery code for the menu at the top of the page and this for fancybox or there is some other reason why I keep getting an error in Firebug "u is undefined" after opening the other part of the PHP page and attempts to re-opening photos?

推荐答案

查看HTML源代码，并确保没有两次声明FancyBox.我只是在萤火虫中弹出了完全相同的错误，这就是我在源代码中找到的:

View your HTML source and make sure you don't have FancyBox declared twice. I just had the exact same error pop up in firebug and this is what I found in my source:

<script language="javascript" type="text/javascript" src="./ext_scripts/jquery.fancybox-1.3.1/fancybox/jquery.fancybox-1.3.1.pack.js"></script>

<link rel="stylesheet" href="./ext_scripts/jquery.fancybox-1.3.1/fancybox/jquery.fancybox-1.3.1.css" type="text/css" media="screen" />  
<script language="javascript" type="text/javascript" src="./ext_scripts/jquery.fancybox-1.3.1/fancybox/jquery.fancybox-1.3.1.pack.js"></script>

不确定为什么会发生，但是不幸的是，如果像我不幸的那样，将include和require_onces嵌套在PHP中，则可以使用一些非常时髦的Javascript引用.

Not sure exactly why it happened, but if you nest your include and require_onces in your PHP like I unfortunately did, you can wind up with some very funky Javascript references.
