I get v_parentform not defined on this line :

   editdoc.body.innerHTML = v_parentform.elements[v_field].value;

in:

function getparentdata()
  { 
   var editor1=document.getElementById('CE_Editor1_ID');
   var editdoc = editor1.GetDocument(); 
   editdoc.body.innerHTML = v_parentform.elements[v_field].value;
  }
