Trouble with IFRAME & Javascript

webguru

I am trying to be able to pass a parameter in my URL to a subpage that
will load the file specified in the paramater into an IFRAME. I have
hardly used Javascript, and am trying to figure out how I would do
this. My URL should always look like this:

http://www.xxx.com/newsite/subpage.h...=filename.html

The javascript I came up with looks like this, because I will only have
one parameter and I know that with the ? and the = that the length of
the param name will always be 6.:

<SCRIPT language="JavaS cript" type="text/javascript">

function GetDocName() {
var
SearchStr, // Search String
DocName, // Name of Document to Use
NameLen; // Length of Document Name

SearchStr = location.search ;
NameLen = SearchStr.Lengt h;
DocName = "documents/"+SearchStr.Sub string(7,NameLe n);
}
return DocName;

</SCRIPT>
What I don't know is how to get the results of the function into my
Iframe. This is what I have tried, with no luck:
<IFRAME height="600" width="780" scrolling="auto "
src="javascript :parent.GetDocN ame()"></IFRAME>
Any help with this would greatly be appreciated!

or

NameLen = SearchStr.Lengt h;
should be SearchStr.lengt h;
DocName = "documents/"+SearchStr.Sub string(7,NameLe n);
'Substring' should be 'substring' and the offset should be 6.

There's little point in assigning variables that are only to be referenced once,
so you could reduce the function to:

function GetDocName()
{
return "documents/"+location.sear ch.substring(6, location.search .length);
}

or to make it independent of the length of the parameter:

function GetDocName()
{
var ls = location.search ;

return "documents/"+ls.substring( ls.lastIndexOf( '=')+1, ls.length);
}
What I don't know is how to get the results of the function into my
Iframe. This is what I have tried, with no luck:

You've been shown that so I won't repeat it.

Suckerfish drop-downs over iframe in FireFox

by: Martial Spirit | last post by:

Hello- I was amazed at the suckerfish drop-downs from AListApart.com. They work great except for one thing, if I position the drop-downs over an iframe element, on mouseover the menus disappear. It works fine in IE, but not FireFox. I would like to implement these menus, but if I can't get this to work, I gotta look at something else. If anyone has some suggestions, I would appreciate it.

I'm using the HTML below as a transition page. It is shown while a page that takes a long time to load is processed (report.asp). It works just fine under IE6 but not Netscape 7. The ReportTransition.htm referenced simply contains this (nothing else): <img src="ReportTransition.gif" /> The following is the html that does not work in Netscape 7, any idea what's wrong with it or a way I could do this better?

Dynamic IFrame Creation Caching Problem

by: polymorphic | last post by:

I have succeeded in embedding PDF files in a dynamic iframe. The problem is that I need the PDF to cache. If the PDF remains the same from page load to page load then the pdf is somehow cached with the html page. But if I try to navigate to another pdf in the IFRAME then no caching occurs. Is the problem in the IFRAME reloading instead of just refreshing the pdf? <SCRIPT type="text/javascript"> var pageNo; var nav; var iframe; var...

For most users, this new feature is actually very convenient. If you want to control the update process,...
