How to hide SharePoint list columns from users based on permission

Question

I need to hide "Approver" add "Title" fields in my SharePoint list. I used the following JS.

<script type="text/javascript" src=class="vglnk" 
href="https://...SiteAssets/jquery-
1.10.1.min.js"</script>

<script type="text/javascript" src= class="vglnk" href="https://...SiteAssets/jquery.SPServ
ices-2014.02.min.js"</script>
<script type="text/javascript">
$(document).ready(function() {
 $().SPServices({
  operation: "GetGroupCollectionFromUser",
  userLoginName: $().SPServices.SPGetCurrentUser(),
  async: false,
  completefunc: function(xData, Approver) {
  var xml = xData.responseXML.xml;

   //If the current User does belong to the group "Test Group"
    if (xml.search('Test Group') == -1)
     {
      //   alert("No, User Doesn't Exists!");                  
       $("select[title=Approver]").parent().parent().parent().hide(); 
       $("select[title=Title]").parent().parent().parent().hide(); 
       //or use: $('td.ms-formlabel:contains("Status")').parent().hide();
      //You can also use:$('nobr:contains("Status")').closest('tr').hide();
       }  
    }
 });
});
</script>

Answer 1

Your code seems fine. You just need to specify with ifs which permissions requires the users that opens the list.

SPServices GetGroupCollectionFromUser() function gets all user's permissions, and in the if you just need to:

//Example
console.log(xml);
xml = ['Read', 'Contribute'];

//If the current User does NOT belong to the group "Contribute"
if (xml.search('Contribute') != -1){
    $("select[title=Approver]").parent().parent().parent().hide(); 
    $("select[title=Title]").parent().parent().parent().hide(); 
}

Make sure the Jquery and SPService library is loaded in the page correctly and here is the completed code which works:

<!-- jQuery Reference. You can refer it from Layouts Folder/Doc Library too, after uploading the script. -->
<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>

<!-- Download SPServices from: http://spservices.codeplex.com/ Or use this CDN  -->
<script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/jquery.SPServices/0.7.1a/jquery.SPServices-0.7.1a.min.js"></script>

<script type="text/javascript">
$(document).ready(function() {
 $().SPServices({
  operation: "GetGroupCollectionFromUser",
  userLoginName: $().SPServices.SPGetCurrentUser(),
  async: false,
  completefunc: function(xData, Status) {
  var xml = xData.responseXML.xml;

   //If the current User does belong to the group "Service desk Operators"
    if (xml.search('Service Desk Operators') == -1)
     {
          //   alert("No, User Doesn't Exists!");                  
           $("select[title=Status]").parent().parent().parent().hide(); 
          //or use: $('td.ms-formlabel:contains("Status")').parent().hide();
          //You can also use:  $('nobr:contains("Status")').closest('tr').hide();
       }  
    }
 });
});
</script>
