你需要这样做：

 ' Define the name and type of the client scripts on the page. 
    Dim csname1 As [String] = "PopupScript"
    Dim cstype As Type = Me.[GetType]()

    ' Get a ClientScriptManager reference from the Page class. 
    Dim cs As ClientScriptManager = Page.ClientScript

    ' Check to see if the startup script is already registered. 
    If Not cs.IsStartupScriptRegistered(cstype, csname1) Then
        Dim cstext1 As New StringBuilder()
        cstext1.Append("<script type=text/javascript> getval('elementid') </") 'Your javascript function
        cstext1.Append("script>")

        cs.RegisterStartupScript(cstype, csname1, cstext1.ToString())
    End If
