Make sure your Javascripts are in the proper location in DotNetNuke

Calling the procedure below in your DotNetNuke module will make sure that your client script will be inserted in the proper place. Which is inside the Head tag.

The Code:

view source

print?

01.Public Sub InjectClientScript(ByVal page As System.Web.UI.Page, ByVal scriptKey As String, ByVal scriptSrc As String, Optional ByVal scriptValue As String = "")

02.    Dim objHead As Control = page.FindControl("Head")

03.    If objHead IsNot Nothing Then

04.        If objHead.FindControl(scriptKey) Is Nothing Then

05.            Dim jQueryControl As New HtmlGenericControl("script")

06.            jQueryControl.ID = scriptKey

07.            jQueryControl.Attributes.Add("type", "text/javascript")

08.            If scriptValue = "" Then

09.                jQueryControl.Attributes.Add("src", scriptSrc)

10.            Else

11.                jQueryControl.InnerHtml = scriptValue

12.            End If

13.            objHead.Controls.Add(jQueryControl)

14.        End If

15.    End If

16.End Sub

Sample:
Inserting a script file;

1.InjectClientScript(page, "jquery.1.3.2.min.js", "/js/jquery.1.3.2.min.js")

Result:

1.<script id="jquery.1.3.2.min.js" type="text/javascript" src="/js/jquery.1.3.2.min.js"></script>

Inserting a plain script;

1.InjectClientScript(page, "jQueryNoConflict", "", "jQuery.noConflict();")

Result:

1.<script id="jQueryNoConflict" type="text/javascript">jQuery.noConflict();</script>
