vbscript variable = javascript variable

i am trying to make a javascript function that contains some asp code so i
can bring info from a database and then loop through the code and write
out all of the "Column2" variables where the "Column1" Variables match a certain number

function clickcombo(elem1,elem2,SelectedItem){
clearcombo(elem2);
'ignore the elem1, elem2, clearcombo and populatecombo2. the main problem
'i am having is getting SI to equal the javascript variable SelectedItem;
<%

Dim SI
Dim Count
SI = %> SelectedItem; <%
Count = 0
Dim cnCity
Dim rsCity
Set cnCity = Server.CreateObject("ADODB.Connection")
Set rsCity = Server.CreateObject("ADODB.Recordset")
cnCity.Open Application("Data_Server")
rsCity.Open "get_City '" & CSTR(SI) & "'", cnCity, adOpenStatic, adLockReadOnly

do while not rsCity.EOF

if SI = rsCity("SID") then 'decide whether StateID = The Selected StateID from the State Dropdown Box

Count = Count + 1
Response.Write "array1[" & Count & "].Value = " & rsCity("City") & ";" & vbcrlf 'Write new JavaScript Array Value
End If
loop

Count.Close
cnCity.Close
Set cnCity.Nothing
rsCity.Close
Set rsCity.Nothing
%>
populatecombo2(elem2, elem1[elem1.selectedIndex].value, array1);

clear array1 'i also don't know how to clear the array in javascript

return true;
}



any help would be very appreciated

 

Think of it this way - SelectedItem exists in the browser, literally - there's a piece of memory with a value in it; your script runs on the server, miles away. How can you assign one to another? You got it all mixed up. This is what you are thinking about (in this case your server code generates JS code):

var js_var = <%= some-vb-code %>

The only way to communicate a JS variable into the script is to submit it with the next HTTP request (e.g. using forms, cookies, JS code, etc). Then use the appropriate server mechanism to retrieve the value. For example:

<%
SI = Request.QueryString("SelectedItem")
%>

J.D.

 

ah, thank you very much. i didn't realize i could just request it.
i have only been doing asp for 2 weeks so this is new territory for me.
thx for the help
