Dear all,

The information are provided here:
1. I have retrive some records from a database, then store it in an array (Varaible of VBS)

2. In that page, I have a combo box control, and I assign the onclick to a javascript function

3. in that javascript function, I need to use the values that are stored in (1), i.e. in the database array , however, I need to know the indexselected to get the value from the array. How can I do this?

it is shown here:
javascript:
function name () {
 How can I get
 Array(document.form.select.value) here???
}

<form ... >
<select ... onclick = "name()">
...

Thanks!

Gives you the selected value.

document.formname.selectname.options[document.formname.selectname.options.selectedIndex].text

Not quite

Try this

document.formname.selectname.options[document.formname.selectname.selectedIndex].value

Sorry, what I mean the value that I would like to retrive is not that is stored in the control objects.
But I have stored them in an VBS array variable.

that is, say
I have :

Array(1) = "value1"
Array(2) = "value2"
Array(3) = "value3"

I want to get
Array(selectedindex)

(Note that the value stored in the array is not equal to the value of the control.value)

You can't access ASP variables directly through Javascript without passing them somehow.

You might do this:

in ASP that generates the page

'Preceeding Asp code here
%>
<SCRIPT>
function whatever {

MyArray = newArray(<%=Array(1)%>,<%=Array(2)%>,<%=Array(3)%>)

}
<%
'following ASP code here

That way you can populate your Javascript array with the same values as the ASP array. However, if you're referencing to the Array index, then both Javascript and VBScript use 0 as the first reference so perhaps do this to keep the references the same:

%>
<SCRIPT>
function whatever {

MyArray = newArray(<%=Array(0),<%=Array(1)%>,<%=Array(2)%>,<%=Array(3)%>)

}
<%


Obviously if an array has a lot of elements you can put this all in a loop to save typing
(javascript)
MyArray = newArray(25)
<%
for x = 0 to 24
%>
MyArray[0] = <%=Array(x)%>
<%
next
'ASP code continues

Hope this is clear

p.s.

If the array contains strings, then you'll have to put quotes around like this

MyArray = newArray(25)
<%
for x = 0 to 24
%>
MyArray[0] = "<%=Array(x)%>"
<%
next

The point is that ASP always executes before Javascript code, so I think you'd be best to pass the ASP array into the Javascript. Then the Javascript can calculate the stuff it needs to and either pass the stuff back to the ASP as hidden form elements with a submit, or just directly display what you need it to display.
