Interference with SCE script frame

Hi,

In my html (generated) I have a script tag (javascript) that gets its source from an aspx (.net) file. Like this -

script LANGUAGE="JavaScript" src="/App/getJSValue.aspx"

(Note: deliberately removed opening and closing tags to make the line visible in the post)

The aspx file basically sets a javascript variable to true or false based upon user session value. The page works fine on web server. But inside TeamSite, when browsing (not previewing from DCR form) the page, it throws an Javascript error. On further investigation I figured out that the aspx file is rendering its output not to the script frame of the main html page but to the script frame of the SCE toolbar. Thats why in the main page the javascript variable is never found and so is the error. When previewing the page from the DCR form the SCE is not enabled and the page works fine without any issue.

Has anyone else have encountered this problem and if yes have you found a resolution?

Appreciate any suggestion.

Thanks

I don't know the answer - but it might help if you showed the code that's trying to access/set the variable - perhaps it's trying to access it from a level of the javascript layer that is taken over by the SCE toolbar? (top., parent., opener., etc.)

The generated page has following scrip snippet in the body of the html
=============================================================
[HTML]
script language="javascript" src="/App/IsLoggedInJS.aspx"></script>
< script language="javascript" >
document.getElementById('spanLogin').innerHTML = (isLoggedIn) ? 'Logout' : 'Login';
< /script
[/HTML]
=============================================================
Again the start and closing tag I have to remove to make the post readable.

And the aspx file is as follows -

=============================================================
[HTML]
< %@ Page Language="vb" AutoEventWireup="false" % >
< %
' Response.Clear()
Response.CacheControl = "no-cache"
Response.AddHeader ("Pragma", "no-cache")
Response.ContentType = "text/html"
Response.Expires = -1
if isnothing(Session("IsLoggedIn")) then
Response.Write("var isLoggedIn = false;")
elseif ctype(Session("IsLoggedIn"),boolean) = true then
Response.Write("var isLoggedIn = true;")
else
Response.Write("var isLoggedIn = false;")
end if
Response.End()
% >
[/HTML]
==========================================================

Hopefully I could make it little clear.
Appreciate your ideas.

Thanks

First - if you enclose the code in [html]...[/html] markers, I believe the code will show up fine - alternatively, you can do what I do which is type <<x>element>...<<x>/element> and it will also show up correctly.

Secondly - have you tried your code with different browsers? IE is brain-dead when it comes to elements with name attributes - it only accepts them on form elements and the work-around is to set id attributes with the same value on multiple non-form elements - which of course goes against the idea that id refers to a unique element within a page. Firefox behaves correctly (IMO) in this regard.

I realize you are using 'id' and not 'name' - but it's possible that this might be a similar browser-specific issue. It's also possible that spanLogin is being used as an id (who knows?) in the SCE / Visual Toolbar.

However - I don't see anywhere in your posted code where you are explicitly setting the 'id' of an element to spanLogin - is this something you were reverse-engineering?

Perhaps someone with more knowledge of aspx and javascript (I hardly claim to be an expert in either) can provide some additional ideas.
