css og asp

<HTML>
<BODY>
<style>
BODY{
  background-color: #<% =strBackgroundcolor %>;
}
</style>

osv.

hej thomas hvad helt præcist gør denne sætning: background-color: #<% =strBackgroundcolor %>;
Jeg må indrømme at  jeg ikke er helt stiv i asp.

Den indsætter asp-variablen strBackgoundcolor i dit stylesheet. Så skal du bare sørge for, at variablen indeholder en tilfældig farve, f.eks. (ikke testet):

<%
Dim strBackgroundcolor
strBackgroundcolor = int(rnd*255) + 1 & int(rnd*255) + 1 & int(rnd*255) + 1
%>
HTML>
<BODY>
<style>
BODY{
  background-color: #<% =strBackgroundcolor %>;
}
</style>

Ups det gik lidt stærkt... prøver lige igen. to sek

Sådan:

<%
Dim strBackgroundcolor
Randomize
strBackgroundcolor = Hex(int(rnd*255) + 1) & Hex(int(rnd*255) + 1) & Hex(int(rnd*255) + 1)

%>
<HTML>
<BODY>
<style>
BODY{
  background-color: #<% =strBackgroundcolor %>;
}
</style>

</body>
</html>

Nu skifter den til en tilfældig farve hver gang du opdaterer. Du kan også sætte den til f.eks. at have en farve pr dag i ugen eller hvad du nu vil.

Ok...  Men hvad nu hvis den skal være rød om mandagen, hvid tirsdag, blå onsdag osv...??

Så gør du sådan her:

<%
Dim strBackgroundcolor
Select Case WeekDay(Now, 2)
Case 1 'søndag'
strBackgroundcolor = "ff0000"
Case 2 'mandag'
strBackgroundcolor = "00ff00"
Case 3 'tirsdag osv'
strBackgroundcolor = "ff00ff"
Case 4
strBackgroundcolor = "0000ff"
Case 5
strBackgroundcolor = "ffff00"
Case 6
strBackgroundcolor = "ffffff"
Case 7
strBackgroundcolor = "00ffff"
End Select
%>
<HTML>
<BODY>
<style>
BODY{
  background-color: #<% =strBackgroundcolor %>;
}
</style>

</body>
</html>

Fik lige byttet rundt på dagene:

<%
Dim strBackgroundcolor
Select Case WeekDay(Now, 2)
Case 1 'mandag'
strBackgroundcolor = "ff0000"
Case 2 'tirsdag'
strBackgroundcolor = "00ff00"
Case 3 'onsdag'
strBackgroundcolor = "ff00ff"
Case 4 'torsdag'
strBackgroundcolor = "0000ff"
Case 5 'fredag'
strBackgroundcolor = "ffff00"
Case 6 'lørdag'
strBackgroundcolor = "ffffff"
Case 7 'søndag'
strBackgroundcolor = "00ffff"
End Select

%>
<HTML>
<BODY>
<style>
BODY{
  background-color: #<% =strBackgroundcolor %>;
}
</style>

</body>
</html>

Jeg syntes ikke rigtigt der sker noget, min kode ser således ud:

<%
Dim strBackgroundcolor
Select Case WeekDay(Now, 2)
Case 1 'søndag'
strBackgroundcolor = "ff0000"
Case 2 'mandag'
strBackgroundcolor = "00ff00"
Case 3 'tirsdag osv'
strBackgroundcolor = "ff00ff"
Case 4
strBackgroundcolor = "0000ff"
Case 5
strBackgroundcolor = "000000"
Case 6
strBackgroundcolor = "ffffff"
Case 7
strBackgroundcolor = "00ffff"
End Select
%>

Det er fordi du har et eksternt stylesheet, som sikkert overruler det nye. Fjern Body {bgcolor: } fra filen style_myg.css og bgcolor="#FFFFFF" i dit body-tag, så virker det.

Prøv dette:

<%
Dim strBackgroundcolor
Select Case WeekDay(Now, 2)
Case 1 'mandag'
strBackgroundcolor = "ff0000"
Case 2 'tirsdag'
strBackgroundcolor = "00ff00"
Case 3 'onsdag'
strBackgroundcolor = "ff00ff"
Case 4 'torsdag'
strBackgroundcolor = "0000ff"
Case 5 'fredag'
strBackgroundcolor = "ffff00"
Case 6 'lørdag'
strBackgroundcolor = "ffffff"
Case 7 'søndag'
strBackgroundcolor = "00ffff"
End Select

Bemærk at jeg har fjernet dit .css stylesheet - det skal du bare sætte på igen, når .css-filen er ændret.

baggrunden er stadig hvid det burde den da ikke være vel?

Det er nok fordi du har angivet at alle dine celler skal være hvide, f.eks.

<td width="50%" height="30" bgcolor="#FFFFFF" bordercolor="#FFFFFF">&nbsp;</td>

Fjern bgcolor="#FFFFFF" alle steder.

hjælp... :-( 
Jeg har fjernet det alle steder, men den er stadig hvad. Jeg syntes ikke at gider skifte farve. koden:

Du er sikker på det ikke er i din iframes, at baggrunden er hvid?

Fjern også bgcolor="" fra dine <td>

Du har også angivet bgcolor i din table.

nu er det vist kan en jeg mangler men jeg kan ikke finde den...

OK... Hvordan får man så IFRAME til at følge samme princip

Kan man ikke få iframe til at følge resten med skift af baggrund farve..?

Jo med <iframe bgcolor="#<% =strBackgroundcolor %>">.

Jeg kan ikke få det til at virke jeg har sat det ind i koden::

<%
Dim strBackgroundcolor
Select Case WeekDay(Now, 2)
Case 1 'mandag'
strBackgroundcolor = "395877"
Case 2 'tirsdag'
strBackgroundcolor = "881313"
Case 3 'onsdag'
strBackgroundcolor = "ff00ff"
Case 4 'torsdag'
strBackgroundcolor = "2F7A9A"
Case 5 'fredag'
strBackgroundcolor = "881313"
Case 6 'lørdag'
strBackgroundcolor = "881313"
Case 7 'søndag'

Burde det ikke virke nu ?

Jeg har fundet ud af det, du skal have mange tak for hjælpen..

Var ikke lige ved computeren... Virker det nu?
