FormData is working inconsistently

more options

In one part of my code (generated by PHP) the following is working correctly:

   FD = new FormData()
   FD.append('V',)
   FD.append('F','add')
   FD.append('D',NewI)
   FD.append('N',N)
   SetReq()

function SetReq() {

   XReq = new XMLHttpRequest()
   XReq.onreadystatechange = function() {XReady()}

XReq.open('POST','NewsIU2.php') XReq.send(FD) } Another part of my code is not working

   var	FD = new FormData()
       FD.append('V',)
       FD.append('F','delete')
       FD.append('D',B)
       SetReq()

When it gets to the PHP program the the first case has $_POST('F') = 'add', the second case is empty

Stack Overflow is normally the worst place to look. Hard to follow. Two cases, one works fine the other fails. It cannot be a coding problem. Some of advance techniques recommended by MDN causing code to quit, like FormData.get()

But you can start your own thread, you don't need to follow someone else's.
