Script in iframe unintentionally halting script in parent

Penguiniator

I have a script that writes the body tag and adds a background
image to its containing page. This page is displayed in an
iframe inside a td tag of a table constructed with javascript.

The table row it appears in is mid-way down the table. When the
script executes in the iframe it halts the parent window's
script, casusing the table to stop rendering after the row
containing the iframe.

I have no control over the code of the parent window.

Is this behavior normal for javascript? Is there anything I can
do with my code to compensate for the behavior of code in the
parent window?

My code:

<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html;

<script>
var backgr2="images/banner2.gif"
var backgr3="images/banner3.gif"
var backgr4="images/banner4.gif"
var backgr5="images/banner5.gif"
var backgr6="images/banner6.gif"
var backgr7="images/banner7.gif"
var cur=Math.round( 7*Math.random() )

if (cur<=2)
backgr=backgr2
else if (cur<=3)
backgr=backgr3
else if (cur<=4)
backgr=backgr4
else if (cur<=5)
backgr=backgr5
else if (cur<=6)
backgr=backgr6
else
backgr=backgr7
document.write( '<body background="'+b ackgr+'"
bgcolor="#00000 0"></body>')
</script>
</html>

backgr = "images.ban ner" + Math.floor(1+Ma th.random()*6) + ".gif"

will do what I suppose you intended there.

Read the newsgroup FAQ, via sig line 2, particularly S 2.3 & S 4.22.

Don't let your posting agent line-wrap your code.

Why not to do more complicated ?
Is it an exercise ?
or do you like too much to slide on your iceberg ?

My code:
is it the code of file in your iframe ?

width (self.document)
{
open();
write('<body background="'+b ackgr+

close();
}
};
</script>

if that doesn't work, try :

onload = function() {
document.body.s tyle.background = "url('+ backgr +

};
