How do you update a selected dropdown value using VBScript - html

Question

I am trying to problematically change the dropdown selection on an InternetExplorer.Application then save that selection. The code I have so far is
dim myValue
myValue="3"
for j = 0 to obj.Options.length - 1
if(obj.Options(j).Value = myValue) then
obj.Options(j).selected = true
exit for
end if
next
This works on the current pages dropdown list, however when I click save, the value "3" isn't saved and it reverts back to its original value when I reload the page.
Another thing to mention is that when I manually click the dropdown and select a value then save, it does update to the new value when I reload the page. I have tried the obj.click function on it but I do not believe a programmatic mouse click works like a actual mouse click with the action listener.
My guess would be something to do with the databinding between the new value selection and the action listener for the page. I am fairly new to vbscript and have tried all sorts of different things.
Any help would be very much appreciated. Thank You!

Supposing you have the obj object set properly, e.g. something like
set obj = ie.document.getElementById("my_dropdown") then you should ensure that only one option is selected:
for j = 0 to obj.Options.length - 1
if (obj.Options(j).Value = myValue) then
obj.Options(j).selected = true ''' do not exit for
else
obj.Options(j).selected = false
end if
next
or
For Each opt In obj.Options
If opt.Value = myValue Then
opt.Selected = True
Else
opt.Selected = False
End If
Next
Caution: above code snippet could result to (undesired?) case that no option remains selected!
