How to write rows into pre-formatted table in second window

Steve

I want to open a window that has been pre-formatted with a table and
then write rows to the table. The pre-formatted url is named
budget.html and the body looks like this:

<body>
<h1 align="center">Budget for <div id=vertical></div></h1>
<table width="100%" cellpadding="0" cellspacing="0">
<tr style="background-color:#000000;color:#FFFFFF;">
<td width="50%">Parameter</td>
<td width="25%">Site-A</td>
<td width="25%">Site-B</td>
</tr>
</table>
</body>

The javascript I have tried is:

function printList() {
window.open('budget.html','budget','width=1000');
function writerow(name,feet,inches,weight) {
budget.document.write("<tr align='center'>");
budget.document.write("<td>"+name+"</td>");
budget.document.write("<td>"+feet+" foot, "+inches+" inch(es)</
td>");
budget.document.write("<td>"+weight+"Kg</td>");
budget.document.write("</tr>");
}
writerow("Michael Owen","5","7","70");
writerow("Emile Heskey","6","2","150");
writerow("Steven Gerrard","6","0","85");
document.close();
//a.print();
}

This gives a firebug message of "budget has no properties". Why?

Thanks in advance for any assistance.

I've never done anything like this before, but I think you need to
give your created window object a variable name.

var budget = window.open('budget.html','budget','width=1000');

var budget = window.open('budget.html','budget','width=1000');

In better words, the window name as specified by the second argument of
window.open() or the `name' property of Window objects have nothing to do
with an identifier in the script.

Instead, the object reference that window.open() returns (if it returns one;
there are popup blockers) must be assigned to a variable or property; this
is _not_ naming the created Window object, it is naming one reference to it.

So this would work as well:

var foo = window.open('budget.html','budget','width=1000');
if (foo)
{
foo.document.write(...);
}
