blocks|key|1158771|text|我遇到了与上面描述的完全相同的问题(messagebox只打开一次)。我遇到的问题是messagebox中的html也加载了jquery。因为我不需要它，所以我可以毫不费力地删除它。否则，您可能不得不进一步确定问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1158772|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I had the exact same problem as the one described above (messagebox only opens once). The problem i had was that the html in the messagebox also loads jquery. Since i don't needed it i could remove it without problems. Otherwise you might have to pin down the problem a bit further.

blocks|key|1374076|text|在某些情况下，如果同时加载多个和不同的JQuery版本，可能会出现此错误。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1374077|在我的例子中，我有一个使用母版的ASP页面。我的主页包含JQuery+1.4.2.min我的aspx页面包含JQuery+1.7.2.min|1374078|当从控件调用JQuery函数时，它对使用哪个JQuery感到困惑，因此即使该脚本可以声明JQuery已加载(它可以显示JQuery版本)，它也无法找到任何JQuery函数。|1374079|当我从aspx文件中删除本地JQuery+1.7.2.min，并将我的mater从1.4.2.min更新到1.7.2.min时，这个问题就消失了。|1374080|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

Under certain circumstances you can get this error if multible and different JQuery version are loaded at the same time.

In my case I has a ASP page that used a master.
My master was including JQuery 1.4.2.min
My aspx page I included JQuery 1.7.2.min

When JQuery functions were called from a control, it got confused about which JQuery to use so even though that script could state that JQuery was loaded ( it could display the JQuery version ), it failed to find any JQuery functions.

When I removed my local JQuery 1.7.2.min inclusion out of my aspx file, and updated my mater from 1.4.2.min to 1.7.2.min, the problem went away.

blocks|key|1158954|text|Doug+Neiner的回答真的很有帮助。我的情况稍微复杂了一点，但仍然是一样的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1158955|我从页面A打开了一个对话框，它加载页面B，如下所示：|1158956|$('#MyDiv').dialog({
++++autoOpen:+false
})
$("#MyDiv").load("PageB.aspx",+function+()+{
++++$("#MyDiv").dialog("open");
});|code-block|syntax|javascript|1158957|问题是页面A和B都包含了jQuery。请注意:如果您正在将另一个页面加载到对话框中，则它不需要包含相同的js。|1158958|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

The answer by Doug Neiner helped really. My case was a bit more complicated, but still comes to same point:

I opened a dialog from Page A which loads Page B like this:

<pre><code>$('#MyDiv').dialog({
 autoOpen: false
})
$("#MyDiv").load("PageB.aspx", function () {
 $("#MyDiv").dialog("open");
});
</code></pre>

The problem is that both Page A and B had included jQuery. Be aware: if you are loading another page into a dialog, it does not need to include same js.

blocks|key|1159007|text|如前所述，您可能会覆盖现有的库。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1159008|处理它的一种方法是确保加载正确的文件。|1159009|另一种方法是在对话框和对话框中的内容之间插入iframe。浏览器将Iframes视为具有其自己的脚本的单独页面。因此，内容的脚本“在”iframe之上，将与“在”iframe下的对话框的脚本分开。|1159010|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

As already explained, you probably override the existing libraries.

One way of dealing with it is to ensure that the correct files are loaded.

Another way is to insert an iframe between the dialog and the content in the dialog. Iframes are treated by the browser as a separate page with its own scripts. So the scripts of the content "on top of" the iframe, will be separate from the scripts of the dialog "under" the iframe.

blocks|key|1159075|text|我也有同样的问题。我的版本是jQuery+UI从1.11.4更新到1.12.1时自己造成的。我使用NuGet和NuGet安装了升级，并从我的项目中删除了旧的1.11.4引用，但从未添加新的项目引用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1159076|在本地运行该应用程序工作得很好，但在部署它时，新的1.12.1文件从未随发布一起发布。我希望这对其他人有帮助。|1159077|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I had the same problem. Mine was self inflicted from a jQuery UI update from 1.11.4 to 1.12.1. I installed the upgrade using NuGet and NuGet removed the old 1.11.4 reference from my project but never added the new project reference. 

Running locally the application worked great, but when deploying it the new 1.12.1 file never made it with the publish. I hope this helps someone else.

blocks|key|1159168|text|另一种可能导致此问题的情况是嵌套布局最终会抑制jqueryUI脚本的呈现。我遇到了这种情况，向后查看了视图文件夹，向后查看了布局，发现“主流”布局没有jqueryUI，只有jquery，尽管jqueryUI是在层次结构的“最上面”布局中指定的。当我显式地将它添加到专门命名的布局文件中时，问题就解决了--尽管我怀疑真正的问题涉及挖掘布局并理解为什么要复制部分。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1159169|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Another situation that can cause this issue is nested layouts that ultimately inhibit the rendering of jqueryUI scripts. I encountered this situation and worked backwards through the view folder and worked backward through the layouts to discover the &quot;prevailing&quot; layout did not have jqueryUI, just jquery, even though jqueryUI was specified in the &quot;topmost&quot; layout in the hierarchy. When I explicitly added it to the specifically named layout file, the problem was resolved - although I suspect the real issue involves digging through the layouts and understanding why sections were duplicated.

I am developing a site using pinax. In one of my templates I am trying to open a simple jquery dialog box. However I keep getting the "Dialog not a function" javascript error. I am using jquery 1.2.6 and jquery-ui 1.6. My javascript and HTML are as follows: 

<pre><code>&lt;html&gt;
&lt;head&gt;
&lt;link type="text/css" href="/site_media/smoothness/ui.all.css" rel="stylesheet" /&gt;
&lt;script src="/site_media/jquery.js" type="text/javascript"&gt;&lt;/script&gt;
&lt;script src="/site_media/ui/ui.core.js" type="text/javascript"&gt;&lt;/script&gt;
&lt;script src="/site_media/ui/ui.draggable.js" type="text/javascript"&gt;&lt;/script&gt;
&lt;script src="/site_media/ui/ui.resizeable.js" type="text/javascript"&gt;&lt;/script&gt;
&lt;script src="/site_media/ui/ui.dialog.js" type="text/javascript"&gt;&lt;/script&gt;
&lt;script type="text/javascript"&gt;
$(document).ready(function(){
 $('#dialogbox').dialog();
 });
 &lt;/script&gt;
 &lt;/head&gt;
 &lt;body&gt;
 &lt;div id="dialogbox" title="dialog title"&gt;
 &lt;p&gt;Test dialog&lt;/p&gt;
 &lt;/div&gt;
 &lt;/body&gt;
 &lt;/html&gt;
</code></pre>

Can someone please explain why this is happening?
