Read and Clear the last line of Multiline Textbox, using JavaScript

When you click on the remove button, use javascript to read the data into an array. Remove the last line and write it back.

Thanks Sojan.

This I am sure your logic would work.

However, I was able to do it without using the array. I am copyimg the code, I used, here.

Though, let me acknowledge, I got the hint from your suggestion.

Hence, thanks all the same, I appreciate your time and effort. 

I was able to do the trick using the following code -

function RemoveLastLine()
{
     var OldData = NWF$('#'+ fldMultiLine).val();   

     if(OldData.lastIndexOf(" ")>0)
    {
          var TruncatedData = OldData.substring(0, OldData.lastIndexOf(" "));
          NWF$('#'+ fldMultiLine).val('');
          NWF$('#'+ fldMultiLine).val(TruncatedData);
      }
     else
     {
          NWF$('#'+ fldMultiLine).val('');
      }
 }

You can also try RegEx to remove the last line.
