无法读取属性"SPCascadeDropdowns" [英] Cannot read property 'SPCascadeDropdowns'

问题描述

用这个再次将我的头撞在墙上.我正在尝试创建一个具有主下拉菜单的页面，该页面将级联为辅助下拉菜单(过滤列表)，但出现此错误:

 
未捕获的TypeError:无法读取未定义的属性'SPCascadeDropdowns'
    < anonymous>. (NewForm.aspx?Source = TheSite.aspx& ContentTypeId = 0x010044DDE520BE4D40439FD3F934B5E958D0& RootFolder =:588)
    在j(jquery.js:3148)
    在Object.fireWith [as resolveWith](jquery.js:3260)
    在Function.ready(jquery.js:3472)
    在HTMLDocument.J(jquery.js:3503)
 

这是NewItem.aspx中SharePoint列表中的代码

< script type =" text/javascript"language ="javascript" src ="//ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"</script>
    < script type ="文本/javascript" language ="javascript" src ="//cdnjs.cloudflare.com/ajax/libs/jquery.SPServices/2014.02/jquery.SPServices-2014.02.min.js"</script>
    < script type =文本/javascript">
$ {document).ready(function()
{
$().SPServices.SPCascadeDropdowns(
{
lationshipList:"MeetingTools"，
lationshipListParentColumn:"Sourcess"，
lationshipListChildColumn:"MtgDates"，
parentColumn:"Sourcess"，
childColumn:"SourceDateTimess"，
调试:true
});
});
</script>

如果我在SPServices行之前放了一个警报，它就在那儿，但是我认为它绕过了SPServices的功能，因为当它试图加载它时，由于某种原因它不能.我已经在IE，Edge甚至Chrome中对此进行了测试.

感谢您提供的信息

嗨布拉德，

要实现此目的，我们可以使用jQuery级联下拉插件，它非常易于使用.

有关更多信息，我们可以参考以下文章.

Banging my head on the wall again with this one.  I am trying to do a page with a main drop down that will cascade into a secondary dropdown (a filtered list) and I get this error:

Uncaught TypeError: Cannot read property 'SPCascadeDropdowns' of undefined
    at HTMLDocument.<anonymous> (NewForm.aspx?Source=TheSite.aspx&ContentTypeId=0x010044DDE520BE4D40439FD3F934B5E958D0&RootFolder=:588)
    at j (jquery.js:3148)
    at Object.fireWith [as resolveWith] (jquery.js:3260)
    at Function.ready (jquery.js:3472)
    at HTMLDocument.J (jquery.js:3503)

This is the code in the NewItem.aspx for the SharePoint list

<script type="text/javascript" language="javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
    <script type="text/javascript" language="javascript" src="//cdnjs.cloudflare.com/ajax/libs/jquery.SPServices/2014.02/jquery.SPServices-2014.02.min.js"></script>
    <script type="text/javascript">   
		$(document).ready(function ()  
		{ 
		    $().SPServices.SPCascadeDropdowns(  
		    {  
		        relationshipList: "MeetingTools",   
		        relationshipListParentColumn: "Sourcess",   
		        relationshipListChildColumn: "MtgDates",   
		        parentColumn: "Sourcess",   
		        childColumn: "SourceDateTimess",   
		        debug: true   
		     });  
		});  
	</script>  

If I put an alert just before the SPServices line, it is hitting there, but then I think it is bypassing the function for the SPServices because when it tries to load it, it cannot for some reason.  I have tested this in both IE, Edge, and even Chrome.

Thanks for the information
