How to Include JavaScript Between Vb.NET
Integrating JavaScript into your Visual Basic .NET (VB.NET) code lets you use both programming languages in a single function. This helps you create dynamic web content for your website with an ASP.NET page. Including JavaScript code in a VB.NET function is done by creating a "ClientScriptManager" object that manages scripts and its "RegisterStartupScript" method, which registers a specific script to the page.

Create a VB subroutine which uses JavaScript code through use of the "RegisterStartupScript" method by adding the following code after the "DOCTYPE" line:
<script runat="server">
Public Sub Page_Load(ByVal sender As [Object], ByVal e As EventArgs)
Dim cs_name As [String] = "Testing JavaScript"
Dim cs_type As Type = Me.[GetType]()
Dim csm As ClientScriptManager = Page.ClientScript
If Not csm.IsStartupScriptRegistered(cs_type, cs_name) Then
Dim cs_text As New StringBuilder()
cs_text.Append("<script type=text/javascript> alert('Using JavaScript!') </")
cs_text.Append("script>")
csm.RegisterStartupScript(cs_type, cs_name, cs_text.ToString())
End If
End Sub
</script>
