Now how can i remove this element… i have been using rowData.splice(), but i have no idea on what to pass to remove it.

In the code you present rowData should be empty, so rowData[0] should be undefined. I suppose something is pushed to rowData in between? Anyway, there are several ways to remove elements from arrays:

• You can remove all elements at once
  from an array using rowData.length =
0.
• If you want to remove 1 element, use
  the Array.splice method. E.g.
  removing the first element:
  rowData.splice(0,1) (means remove
  1 element of rowData starting from
  element 0 (the first element).
• If it’s only the first element you
  want to remove you could also use the
  shift method: rowData.shift().
• The last method you can use is
  slice: rowData = rowData.slice(1)
  (means: give me all elements from
  rowData starting at the first element and
  assign the result to rowData),
  or rowData.slice(1,4) (means:
  give me all elements from
  rowData starting at the first element,
  ending at the fourth element, and
  assign the result to rowData).
