Reprocess page after document.write

I am working with a special tool which pre-processes the page. Using
document.write, I am composing the page while it is loading, so I need
to force a reprocess of the page AFTER the page loads.

Is there some way to do that? That is, I want the browser to
essentially act as if the composed page was the original page.

Here is a brief version of the page construction technique:

<!DOCTYPE HTML SYSTEM "-//W3C//DTD XHTML 1.0 Strict//EN">

function oneitem(curp,chkVls,chkNms) {
alert('curp:'+curp+',name:'+chkNms[curp+11]+",val:"+chkVls[curp+11]);
var cma=0;var cmb=0;var retstr=' ';
if (chkVls[curp+11] == 1) {
if (chkVls[curp] == 1) {cma=1;}
if (chkVls[curp+5] == 1) {cmb=1;}
retstr='{sq'+'l} INSERT into shal';
retstr=retstr='tpkd.cmfform(pw=haltpwd) {\s'+'ql}';
}
return (retstr);
}
// get document.location, decode, assign
var chkStr = document.location.href.split('?')[1].split('&');
var chkNms = document.location.href.split('?')[1].split('&');
var chkVls = document.location.href.split('?')[1].split('&');
for(var x=0; x<chkStr.length; x++)
{
var tmp = chkStr[x].split('=');
chkNms[x]=unescape(tmp[0]);
chkVls[x]=unescape(tmp[1]);
eval(unescape(tmp[0]) + '="' + unescape(tmp[1]) + '"');
}
var restpage='<!DOCTYPE HTML SYSTEM "-//W3C//DTD XHTML 1.0 ';

Hi Paul,

A suggestions that comes into mind (without any knowledge of all the
difficulties your are in):
Why not buffer the complete output in a var, and when done, write that?

What is failing?

You only need to escape the </script> tag. An easier way to do this is:
<\/script>. When a browser sees, <script> it scans for the </script>
tags. Some browser ignore things in quotes in when doing this scan.
Hence the need for escaping.

See RobG's explains how to construct a string containing html. Grooge
won't let me point to one post but only a thred. Here is the thread:

Here is RobG's code. Hope he doesn't mind.

function loadWindow() {
var VE3DWindow = window.open('',

VE3DWindow.document.write(a.join(""))

There are a lot of bugs in the posted code. Try running the code in
Firefox and look at the javascript console. I made some changes but
after the first 7 errors I have stopped. The first error was a missing
</script> tag on the first script line.

the line:
restpage=restpage+'Strict//EN">';
can be written as:
restpage += 'Strict//EN">';
