Dynamic js file at runtime 1

TallOne · May 18, 2009

Hi all,

At the bottom is the head section of my aspx page. I want to set the src prop of the script at run time.

src="Scripts/iphonenavIE.js"
or
src="Scripts/iphonenavSafari.js"

If I add an ID and RUNAT props I get tons of unrelated errors on build and intellisense doesn't recognize the object. I'm using Web Application and cannot access the designer pages.

Can anyone tell me what I'm missing here???

I've tried

Code:

IF .... Then
ClientScript.RegisterClientScriptBlock(Me.GetType(), "Navigation", "<script language='javascript' src='Scripts/iphonenavIE.js'/>")
Else
ClientScript.RegisterClientScriptBlock(Me.GetType(), "Navigation", "<script language='javascript' src='Scripts/iphonenavIE.js'/>")
End If

BTW it works with links.... but not scripts!

Code:

<link id="linkStyle" runat="server" rel="stylesheet" type="text/css" />

CODE BEHIND

Code:

linkStyle.Attributes.Add("href", clsUtility.xReturnStyle())

Code:

<head>
<title>iPhone Navigation</title>
<link id="linkStyle" runat="server" rel="stylesheet" type="text/css" />

<meta name="viewport" content="width=320; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;"/>
<style type="text/css" media="screen">@import "Style/iPhoneNav/iphonenav.css";</style>
<script type="text/javascript" src="Scripts/iphonenavIE.js"></script>
</head>

If you add a runat="server" you are instructing the script to actually run on the server. Instead, use a Literal control and write the <script> tag out as necessary.

when adding js scipts to a page you cannot use self closing tags.

Code:

<script language="javascript" type="text/js" src="../file.js></script>

Code:

<script language="javascript" type="text/js" src="../file.js />

Thanks ca8msm. I ended up combining js files to keep my logic in one place. For learning purposes and in the event I need to use this technique in the future, what's the correct usage? Are asp:controls allowed in the head tag?

Code:

<head>
   <asp:Literal id="Literal1" runat="server"></asp:Literal>
</head>

Code:

'Page Load & Not Postback
Literal1.Text = "<script language='javascript' src='Scripts/iphonenavIE.js'/>"

Make your <head> tag runat="server"

Code:

    Public Shared Sub AddJSToPage(ByRef header As HtmlControls.HtmlHead, ByVal FileName As String)
                Dim IncludeJS As New HtmlGenericControl("script")
                IncludeJS.Attributes.Add("type", "text/javascript")
                IncludeJS.Attributes.Add("src", "Your Application Path Here"+ "js path and filename here")
                header.Controls.Add(IncludeJS)
    End Sub
