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.EventArgs) Handles MyBase.Load
Dim Fruit() As String = {"Apples", "Bananas", "Grapes", "Pears"}
Dim s As New System.Text.StringBuilder
s.Append("<script>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>")
RegisterClientScriptBlock("Fruit", s.ToString)
s = New System.Text.StringBuilder
s.Append("<script>var i; var s = '';")
s.Append("for (i = 0; i < arr.length; i++)")
s.Append("{s = s + arr[i] + ' '}")
s.Append(" document.all('TextBox1').value = s;</script>")
RegisterStartupScript("Show", s.ToString)
End Sub
