How to give default value?

P

Paul

HI! I use iframes and I need to set a default value so if the user enters
the page directly he does not get an empty iframe.

I use this to query the var ( ifp )

<iframe src="<%=Request.QueryString("ifp")%>"></iframe>

Now should I set a session var so that the if the user enters the site he
will get whatever I set at the beginning of the users session?
OR
should I set an IF statement on the Iframe page.?

<SCRIPT language="JavaScript">
If (ifp==""){
ifp="default.htm"}
//--></SCRIPT>

<iframe src="
<% IF Request.QueryString("ifp") <>"" Then %>
<%=Request.QueryString("ifp")%>
<% Else %>
<% ifp= "whatever" %>
<% End IF %>">
</iframe>

Where "whatever" can be as session variable or constant

HI! I am still having problems, I use what you mentioned but It does not
accept the Iframe values that I give it.

<iframe src="<% IF Request.QueryString("ifp") <>"" Then %>
<%=Request.QueryString("ifp")%>
<% Else %>
<% ifp= "Template_Code_Files/All_featured_template_for_iframe.htm" %>
<% End IF %>">
name="Iframe001" width="750px" height="920px" scrolling="yes"
id="Iframe001">If you are reading this then your browser cannot view Iframe,
Please upgrade you borwser.</iframe>

The height and width and other params are not being used by the browser. and
it does not load the file that I specified either. Is there something else
missing here?

I tried it as writen above and on a single line.

NOTICE: If I just use the code below it works ( but it does not have a
default value at this point )

<iframe src="<%=Request.QueryString("ifp")%>" name="Iframe001" width="750px"
height="920px" scrolling="yes" id="Iframe001">If you are reading this then
your browser cannot view Iframe, Please upgrade you borwser. </iframe>

I use this from another page.
<a
href="mainpage.asp?ifp=Template_Code_Files/All_featured_template_for_iframe.htm">Click</a>

To use a default value should I define it as a session variable?
Is it possible to define the session var in the global.asa

The reason it still doesn't work is because you attempted to populate the
ifp parameter of the QueryString using the conditional 'else' as if the ifp
parameter were actually a variable instead of a parameter of the QueryString
method which it actually is in the code as written.

The ifp parameter should be declared and initialized as a variable when
using it in this context. I haven't written ASP for awhile but its kinda
like riding a bike. So try this...

<%
' initialize ifp variable using QueryString value
dim ifp
ifp = Request.QueryString("ifp")

' if the ifp variable is not an empty string
if ifp <> "" then
%>

<!-- use value of ifp variable to initialize the iframe src attribute -->
<iframe src=<%= ifp %>

<% else %>

<!-- initialize iframe src attribute with default value
<iframe src="Template_Code_Files/All_featured_template_for_iframe.htm" >
<% end if %>

I don't want to write a tutorial regarding the difference betwen parameters,
values of parameters, and variables but this topic did keep me confused for
awhile when I started learning web developent. You should do some study on
the topic.

HI! Thanks, I will research this. I do find it a little confusing. I will
take notes of it as its easy to get mixed up between the two. I am still a
little lost. but thanks you for shedding light on it :)
