I have a list on SharePoint Online, where I need to make sure that only one person can edit a list item at a time. For example, if Person A edits a list item, it MUST be clear to everyone else working, that Person A is working on this list item and no one else should be able to edit this item.

As this is a list I am unable to turn the check in/check out feature on like I could if it was a document library.

Any suggestions would be much appreciated.


I have tried adding the below code to both the NewForm.aspx and Edit Form.aspx pages but it doesn't seem to work:

<script type="text/javascript" src="/%20sites/Devsite%20/SPServices.0.7.2.js"></script><script type="text/javascript" src="/sites/Devsite/jqueryv1.8.3.js"></script><script type="text/javascript">  
var loggedInUser="";  

     document.getElementById('CheckedOutTo_8eb26269-8497-4b14-9785-ca206415c404_$TextField').disabled = true;  
     var checkInOutValue=$('[name="CheckInOut_9c53da6b-28f9-4200-9823-36913cf0e610_$RadioButtonChoiceField1"]:radio:checked').val();  
     var checkedOutToValue=document.getElementById('CheckedOutTo_8eb26269-8497-4b14-9785-ca206415c404_$TextField').value;  
     var thisUsersValues = $().SPServices.SPGetCurrentUser({  
         fieldNames: ["Name", "Title"],  
         debug: false  
//if the user doesn’t belong to the CheckedOutTo field then don’t allow the //user to edit an item .instead redirect the user to allitems.aspx page  
             alert("This item is checked out to: "+checkedOutToValue+". You will not be able to edit this item.");  


 function radioButtonChange()  

             var checkInOutValue=$('[name="CheckInOut_9c53da6b-28f9-4200-9823-36913cf0e610_$RadioButtonChoiceField"]:radio:checked').val();  
     else if(checkInOutValue=="Check-In")

  • Thanks Karthik. I have followed these instructions and changed the field ID's to match mine but unfortunately it isn't working. I have updated my main post with the code I have added to both the New and Edit form pages.

There is no OOTB method to block editing a list item when another user already edits. You need to do Custom code or JQuery/JSLink.
