Adding/removing a combobox item using client side scripting

Here are some sample codes in VBscript:

1. To remove an item from a combo box named 'Color'
Sub RemoveItem

Dim oChild
Set oChild =
document.GetElementById("Color").children(3)
document.GetElementById("Color").removeChild(oChild)
Set oChild = Nothing

End Sub

2. To add an item to a combo box named 'Color'
Dim a
a=1

Sub AddItem

Dim objOptSet
objOpt= document.CreateElement("OPTION")
objOpt.Value = a
objOpt.Text = "Green"
Color.add objOpt
Set objOpt = Nothing
a = a + 1

End Sub

Useful but easily forgotten VB functions

When you have an array but a string is all you need, use:
Join(sourcearray[, delimiter])


When you have a string of values separated by a delimiter, like a comma or a semi colon, but you need to have them in an array, use:
Split(expression[, delimiter[, limit[, compare]]])
