problem with insertAdjacentHTML

Phil · Apr 27, 2004

Hi all,

I am trying to use the code below so as to create a frame source string
dynamically. The idea is to verify if this index page is the parent or if it
called by an orphan page, in which case the orphan page passes its own name
as an argument to the index page.
Unfortunately, the code below returns an unspecified error.
This code is what is intended to create the index.htm page as it opens.

<HTML><TITLE>....</TITLE>

<SCRIPT type="text/javascript">
function window.onload()
{
checklocation();
}
function writetop()
{
document.body.insertAdjacentHTML('beforeEnd','<FRAMESET cols=20%,*
FRAMEBORDER="1" BORDER="1" scrolling=auto>')
document.body.insertAdjacentHTML('beforeEnd','<noframes>')
document.body.insertAdjacentHTML('beforeEnd','</noframes>')
}
function writebottom()
{
document.body.insertAdjacentHTML('beforeEnd','</FRAMESET>')
document.body.insertAdjacentHTML('beforeEnd','</HTML>')
}
function checklocation()
{
//alert(top.location.href.length);
var theData;
var begin;
begin = top.location.href.indexOf("?");
if (begin > 0 )
{
theData = top.location.href.substring(begin+1,location.href.length);
theData = unescape(theData);
writetop();
document.body.insertAdjacentHTML('beforeEnd','<FRAME name=main
src="files/ + theData + ">')
}
else{
writetop();
document.body.insertAdjacentHTML('beforeEnd','<FRAME name=main
src="files/Help.htm">')
}
writebottom();
}
</script>
<body>

</body>
</html>
TIA

Here is perhaps a simplier way to accomplish your goals:

<HTML><TITLE>....</TITLE>

<SCRIPT type="text/javascript">
//alert(top.location.href.length);
var theData;
var begin;
var url = "files/Help.htm";
begin = top.location.href.indexOf("?");
if (begin > 0 )
{
theData = top.location.href.substring(begin+1,location.href.length);
theData = unescape(theData);
url = "files/ + theData;
}
</script>
<FRAMESET cols="20%,*" FRAMEBORDER="1" BORDER="1" scrolling="auto">
<script type="text/javascript">
document.write("<FRAME name=main src='"+ url+"'>";
</script>
</FRAMESET>
</html>

One thing to notice is that you are missing a FRAME definition. I don't know
if that is intentional or not but perhaps that is the reason for your error
because you specify 2 frames in your frameset (cols="20%,*) but then only
define one.

The missing frame reference was unintentional but is present in the
'real' frameset.
In regard to your code: simple and graceful are 2 words that come to
mind.

Many thanks

You are missing quotes after "files/
Even simpler below?
<SCRIPT type="text/javascript">
var url = "files/Help.htm";
if (top.location.search ){
url = "files/" + unescape(top.location.search.substring(1))
}
</script>
