'SPServices' is null or not an object

Question

I need to find out if logged in user belongs to a specific sharepoint group (2010). I am using below code to get it. but getting javascript error as 'SPServices is null or not an object'.

    <script src="/sites/XXX/XXXX/jquery-1.7.2.min.js" type="text/javascript"></script>
<script src="/sites/XXX/XXXX/jquery.SPServices-0.7.1a.min.js" type="text/javascript"></script>
<script type="text/javascript">


$(document).ready(function () {

        $().SPServices({
            operation: "GetGroupCollectionFromUser",
            userLoginName: $().SPServices.SPGetCurrentUser(),
            async: false,
            completefunc: function (xData, Status) {

if ($(xData.responseXML).find("Group[Name='Site Admin']").length == 1) {
                    alert("User in a group");
                }
else{
alert ("User is not in group");


}
            }

        });

    });</script>

So many are saying the error occurs if jquery files not referenced properly. I stored the files in a doc library and referencing it in javascript.

Answer 1

Ì had this issue when loading jQuery on the page and later adding jQuery to the master page for the site.

It can be useful to use the web debugger in Chrome to view exactly which scripts are being loaded.

1. Press 'F12' to launch the tool
2. Open the 'Resources' Tab
3. Expand the frames then the page folder
4. The scripts folder will show all the currently loaded scripts.

Check here to see if you have any duplication.

Answer 2

I just kept the Content editor webpart at bottom in the webpart zone. that's it. it is working fine now.

Answer 3

Here is an example that shows how to reference the js files present in Document Library.

<script type="text/javascript" src="/Shared%20Documents/JS/jquery.min.js"></script>
<script type="text/javascript" language="javascript" src="/Shared%20Documents/JS/jquery.SPServices-0.6.2.min.js"></script>

Here I perform a somewhat similar task: http://sharepointnadeem.blogspot.in/2011/09/hide-sharepoint-list-field-based-on.html
