Repeating Conrol + Current user Name + Time

If that doesn't work try this.  It should change the text field every time either comment or title is changed.

Add a calculated column outside the repeating section set to currentuser.  Store the Client ID in JS variable as currentUser

inside the repeating section add a calculated column with this formula:  user(currentRowNumber() , comment, Title) where comment and Tile are the names of the text boxes in the repeating section.

Add a text box with a css class userName.

Repeating section CSS class: myrepclass

Then paste this in JS

  function user(rowNum, value, valueTitle) {
  repeatingSection = NWF$('.myrepclass');
if (value != "" || valueTitle != ""){
   var currentUse = NWF$('#' + currentUser).val();

   NWF$(".myrepclass .nf-repeater-row").each(function(index){
  
    var $row = NWF$(this);    if( index  == rowNum) {
      $row.find(".userName input").val(currentUse);    }
   
   });
}
}

You can hide calculated column in CSS with display: none;

1.  Once you get it fixed and working add a css class to the calculated column like hideMe.  then add this in the CSS

.hideMe {

display: none;

}

2.  add an alert in different places to see what is happening when you change the value.

After if( index  == rowNum) {  add this

alert(index);

alert(rowNum);  see what is happening.  it should only alert you when the rowNum from your function and index from for each are equal.

Did you make sure the css class is userName?

Paste from your form the JS bake to here to make sure it copied correctly.

This should only change the row that you modified a field in.  If you put the alerts after the If statement, you should only get 2 alerts and it should be the current row number.

You are only wanting to update one row correct?

Ah, forgive me, I cheated on my testing,  I see the problem now.  add two more single line text boxes in your repeating row with these properties

CSS class:  comment hideMe  ........ JS variable:  commentTwo

CSS class:  title hideMe    ................JS Variable:  titleTwo

Then replace your JS with this.  This will compare the title and comment to previous values.  If the same nothing happens...if different it will update the hidden text box and the username.

var valueT = NWF$('#' + commentTwo).val();

var valueTitleT = NWF$('#' +titleTwo).val();

  function user(rowNum, value, valueTitle) {

  repeatingSection = NWF$('.myrepclass');

if (value != valueT || valueTitle != valueTitleT){

alert("this ran");

   var currentUse = NWF$('#' + currentUser).val();

   NWF$(".myrepclass .nf-repeater-row").each(function(index){

    var $row = NWF$(this);    if( index  == rowNum) {

      $row.find(".userName input").val(currentUse);

      $row.find(".comment input").val(value);

$row.find(".title input").val(valueTitle);

     }

   });

}

}

Parker Petty​ Thanks for your help.

What I did is once the user updates the comment at particular row I will make that row read only and by using below script I can update the particular row in which update take place .I have used a javascript to make rows visible to user according to some query string value so that one user can update only one row. But it will be better If you or me find the solution

  function user(rowNum, value, valueTitle) {

  repeatingSection = NWF$('.myrepclass');

if (value != valueT || valueTitle != valueTitleT){

alert("this ran");

   var currentUse = NWF$('#' + currentUser).val();

   NWF$(".myrepclass .nf-repeater-row").each(function(index){

    var $row = NWF$(this);    if( index  == rowNum) {

var checkvalue=$row.find(".userName input").val();

if(checkvalue !=" ")

{

if(checkvalue!=currentuse)

{

      $row.find(".userName input").val(currentUse);

      $row.find(".comment input").val(value);

$row.find(".title input").val(valueTitle);

     }

}

if(checkvalue==" ")

{

   $row.find(".userName input").val(currentUse);

      $row.find(".comment input").val(value);

$row.find(".title input").val(valueTitle);

}

}

   });

}

}

Parker Petty​ Thanks a lot for your help. According to the requirement the comment is to be modified only once so I am able to achieve that with my above code.
