Permission to Add Replies to List Items For Discussion List in SharePoint 2013 Using jQuery

Introduction

This article explains how to restrict permission only for a specific group for a Discussion Content Type in SharePoint 2013 using jQuery.

Prerequisites

Ensure you have a SharePoint site.

The following is the scenario:

• To provide permission for a certain group for a Discussion Content Type in NewForm.aspx/EditForm.aspx in SharePoint 2013 list forms.
• Permission to add replies but not to create new list items for discussion board

Use the following procedure:

1. Create a group called "Test Group".
2. Remove your account from the Test Group.
3. Create a Discussion Board called TestDisp.
   
   
   
   
4. Now navigate to the NewForm.aspx page.
5. Syntax: http://yoursitecollection/Lists/ListName/NewForm.aspx
   In our example: http://yoursitecollection/Lists/TestDisp/NewForm.aspx
6. Go to settings and edit the page.
   
   
   
   
7. Click on Add a Webpart and add Content Editor Webpart.
   
   
   
   
8. Now add a reference to jQuery JavaScript Library v1.8.3 and SPServices - Version 0.7.2 jQuery file.
   

   <script type="text/javascript" src="/ sites/Devsite /SPServices.0.7.2.js"></script>
   <script type="text/javascript" src="/sites/Devsite/jqueryv1.8.3.js"></script>

9. Now add the following lines of code:
   
   

   <script type="text/javascript">
   function PreSaveAction()
   {
       var checkForGroup=false;
    checkForGroup= CheckIfuserBelongsToGroupOrNot();
       if(checkForGroup==true)
       {
   //current user has permissions.So the user can create the discussion item.
           return true;
       }
       else
       {
           alert('Sorry! You do not have permission to create.Please contact site collection administrator for necessary permissions' );
           return false;
       }
    }
   function CheckIfuserBelongsToGroupOrNot()
   {
       $().SPServices({
           operation: "GetGroupCollectionFromUser",
           userLoginName: $().SPServices.SPGetCurrentUser(),
           async: false,
           completefunc: function (xData, Status) {
               var xml = xData.responseXML.xml;
   //In Our Example its Test Group.
               if($(xData.responseXML).find("Group[Name='Enter the Group Name Here ']").length == 1)
               {
                   //current user belongs to group
                   checkForGroup=true;
               }
               else
               {
                   checkForGroup=false;
               }
           }
       });
   }
   </script>

10. Now click on ok and stop editing the webpart.
11. That's it!
12. Now let's start testing.

Testing

1. Enter a value and click on the save button.
   
   
   
   
2. You will not be able to save the discussion item.
