It s actually a simple answer   Your function is returning a string rather than the div node  appendChild can only append a node    For example  if you try to appendChild the string   var z     lt p gt test satu dua tiga lt  p gt       is a string  document body appendChild z     The above code will never work  What will work is   var z   document createElement  p       is a node z innerHTML    test satu dua tiga   document body appendChild z

In my case  there was no string on which i was calling appendChild  the object i was passing on appendChild argument was wrong  it was an array and i had pass an element object  so i used divel appendChild childel 0   instead of divel appendChild childel  and it worked  Hope it help someone

use ondragstart event  instead of ondrag event

This can happen if you accidentally are not dragging the element that does have an id assigned  for example you are dragging the surrounding element   In that case the ID is empty and the function drag   is assigning an empty value which is then passed to drop   and fails there    Try assigning the ids to all of your elements  including the tds  divs  or whatever is around your draggable element
