Automating Internet Explorer with Excel VBA and JavaScript

[chris_j_adams]

Hi,

I'm trying to use Excel VBA ('97) to send details from an Excel sheet
to a web page. I'm having some success but I've one issue that's
proved difficult to find in the archives.

There are a number of elements (ie. text boxes) on this web page that
are conditionally "greyed out". They should become visible (ie. not
greyed) when a prior element is entered with data. However, this is
not happening. The elements are being filled, but they are not
becoming visible.

As a result, when I click the "Submit" button at the bottom of the
page, I get error messages saying these elements are required. Data
has definitely been entered into these elements, but because the
elements do not become un-greyed, I suspect the data is not being
captured.

I viewed the source code and found what looks like a command associated
with these elements: onchange="rethinkChargeCurrency(1)". This
suggests a variable, rethinkChargeCurrency(1) is being changed upon a
change in the element. However, I could not find any further reference
to this variable.

I've not much knowledge of JavaScript and I wonder if I need to put a
check in my code to "enable" these fields? Or do I need to change this
variable?

I've put an example skeleton of my code below. Hope it is sufficiently
illustrative.

Many thanks in advance for any help provided.

Sub startIexplore()

Dim IeApp As InternetExplorer
Dim i As Integer
Dim nm as String

'Open Web
Set IeApp = New InternetExplorer
IeApp.Visible = True
IeApp.Navigate "http:\\WebAddressGoesHere.com"
Do: Loop Until IeApp.ReadyState = READYSTATE_COMPLETE

With IeApp.Document.forms("form")
' Fill in names - these are the elements that need to be filled
in to un-grey the others
For i = 0 To 4
nm = "sources[" & i & "].name"
.elements(nm).Value = "S" & i
Next i

' Type - these are the elements that will be un-greyed, upon
completion of "names"
For i = 0 To 4
nm = "sources[" & i & "].type"
.elements(nm).selectedIndex = 2
Next i

.submit ' I get error messages on the following pages,
saying the "types are required"

End With

IeApp.Quit

End Sub

(I've made an assumption that cross-posting is acceptable in this case,
sorry if not).

The following solution was posted in the
microsoft.public.excel.programming newsgroup.
It worked, although I had to be selective with which elements I
included the statement (not sure why, I'll try to work the reason out
for this later).

With IeApp.Document.forms("form")
' Fill in names - these are the elements that need to be filled in to un-grey the others
For i = 0 To 4
nm = "sources[" & i & "].name"
.elements(nm).Value = "S" & i

Try whether doing
.elements(nm).onchange
here helps.
