how to RegisterStartupScript JS.file

[Stan Sainte-Rose]

Hi,
I m working on a user control.
I need to use a Js file, I would like to know how to load the js file using
RegisterStartupScript command from the user control.
Also, if I load the same user controls several times in the same webpage, do
I have to check if the js file is still loaded ?

Maybe this would work:
RegisterStartupScript(someVariable,"<script
language='javascript'´src='yourInclude.js' />")

cheers,

Hi Mortb

I ve tried what you've said.. but it doesn't work for me.
Do not forget, I would like to use this within a user control.

Be sure to send the startup script to the base page from your user control ... something like:

Dim strScript As New System.Text.StringBuilder()
Dim basePage As Page = Me.Page
Dim ScriptNameAsString as String = "SCRIPTNAME"

strScript.Append("<script language='javascript'´src='yourInclude.js' />")

If Not basePage.IsClientScriptBlockRegistered(ScriptNameAsString) Then basePage.RegisterClientScriptBlock(ScriptNameAsString, strScript.ToString)

Hi Thomas,

It sounds good.. I ve just a little problem.
I see the <script language='javascript' src='yourInclude.js'> comes inside
the <Form>
and my page has lost its design.
How could I get this tag outside the <form> tag ?

Thanks.

I think that is a function of the Page methods that register scripts - that is they are designed to place the text in the form tags ...

RegisterClientScriptBlock - The client-side script is emitted just after the opening tag of the Page object's <form runat= server> element.The script block is emitted as the object that renders the output is defined, so you must include both tags of the <script> element.

RegisterStartupScript - Similar to the RegisterClientScriptBlock method, this method emits the script just before the closing tag of the Page object's <form runat= server> element. The script block is emitted as the object that renders the page is defined, so you must include both tags of the <script> element.

Yes,

I use
If Not basePage.IsStartupScriptRegistered(ScriptNameAsString) Then
basePage.RegisterStartupScript(ScriptNameAsString, strScript.ToString)

But, when a function is called from my form it doesn't find the javascript
function :-(

If I use the your example, it works fine but as I said it breaks my design..

Ok, I ve found the problem.
It's strScript.Append("<script language='javascript'
src='myjsfile.js'></script>")
and not
strScript.Append("<script language='javascript' src='myjsfile.js'/>")

and it works fine with
If Not basePage.IsClientScriptBlockRegistered(ScriptNameAsString) Then
basePage.RegisterClientScriptBlock(ScriptNameAsString, strScript.ToString)



Thanks

[Thomas Dodds]

using RegisterStartupScript implies that you will be calling that script
from a client generated event... how are you using it?

 

[Stan Sainte-Rose]

yes..
I use something like this :
Saisie.Attributes("onblur") = "TypeChamps(this,'" & Row("TypeTest") & "');"

 

[Stan Sainte-Rose]

no problem

I haven't ever used the <script ... /> syntax ... I merely copied something
from a previous post ... my apologies ...
