Hi,
Chris is totally right. I started working on this before I saw Chris' post.
He's got the solution for you. My solution is just a variation on his. All
mine adds is how to run through the array after it's on the client. It also
uses a couple different techniques.
* place a text box on an ASPX page
* Add the following to the code-behind
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles MyBase.Load
Dim Fruit() As String = {"Apples", "Bananas", "Grapes", "Pears"}
Dim s As New System.Text.Str ingBuilder
s.Append("<scri pt>var arr = new Array(")
Dim i As Integer
For i = 0 To Fruit.Length - 1
s.Append("'" & Fruit(i) & "'")
If i < (Fruit.Length - 1) Then
s.Append(",")
End If
Next
s.Append(");</script>")
RegisterClientS criptBlock("Fru it", s.ToString)
s = New System.Text.Str ingBuilder
s.Append("<scri pt>var i; var s = '';")
s.Append("for (i = 0; i < arr.length; i++)")
s.Append("{s = s + arr[i] + ' '}")
s.Append(" document.all('T extBox1').value = s;</script>")
RegisterStartup Script("Show", s.ToString)
End Sub

What ASP.NET sends to the browser is plain text, not objects. You need to
keep in mind that you have two different programming models - one on the
server, and one on the client. If you aren't writing the text for the
client side on the server-side code, then the client isn't getting it. The code
you display here assumes that the client can, in some way, communicate with
the server and get that variable, and that this variable will be type
compatible. Neither assumption is true.
Instead, you need your server side code to write out the code to
initialize this array. Instead of just databinding to the array type, you'll have to
iterate through the array and write it all out:
(my vbscript skills are very rusty, so don't type this in directly, but
you get the idea...)
var x = new Array(10);
<%
dim i
for i = 0 to Len(myArrayAsp) - 1
' Assumes 0-based on client and 1-based on server
Response.Write "x[" & i & "] = " & myArrayAsp(i + 1) & ";"
next i
%>
