Script in iframe unintentionally halting script in parent

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:

if (cur<=2)
backgr=backgr2

backgr=backgr3
else if (cur<=4)
backgr=backgr4
else if (cur<=5)
backgr=backgr5

backgr=backgr7
document.write('<body background="'+backgr+'"

backgr = "images.banner" + Math.floor(1+Math.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 ?

is it the code of file in your iframe ?

Why xmlns ?

onload = function() {
width (self.document)
{
open();
write('<body background="'+backgr+
'" bgcolor="#000000"><\/body>');
close();
}
};

if that doesn't work, try :

onload = function() {
document.body.style.background = "url('+ backgr +
') repeat top left #000000";';
};
