Firefox document.submit has no properties

[Scezic]

Hi, I just started trying to figure out javascript and I'm having a problem with some code in Firefox. I'm trying to convert an existing vbscript/php page. The page contains a switch to edit, update, delete, and add to a database. I understand that it is difficult to pass a value from javascript back to php on the same page so I decided to make a function that uses hidden fields and submits the page so that php can get the new post variables to set the switch. Here is what I did to set Delete:

function DeleteEntry(ID)
{
var rtn = confirm("Are you sure you want to delete this record?");

if (rtn == true)
{

document.writeln("<form method='POST' id='delData' name='delData'>");
document.writeln("<input type='hidden' name='Mode' value='DELETE'>");
document.writeln("<input type='hidden' name='CollectionID' value=\"" + ID + "\">");
document.writeln("</form>");
window.document.delData.submit();
}
}

I need Mode and CollectionID to get repassed through post, which this does in IE but in Firefox JavaScript Console I get Error: window.document.delData has no properties. Any suggestions as to what is going on? Also I'm unclear about the escape quotes for value = ID. This does work to pass the value but the notation seems strange to me.

Thanks.

document.forms.delData?

If you want to send info to PHP, how about sending it via the URL.
No need to create a form, just:

window.location.href = www.example.com/blah.htm?Mode=nuts&CollectionID=bananas;

Thanks for the reply.

I might not understand correctly but document.forms.delData.submit() gives the same error. The current page uses POST to get the information, and from what I understand I'd have to use GET to use the url method.

If I do something like this:
document.writeln("<form method='POST' id='delData' name='delData'> test");

a page with 'test' shows briefly then the page reloads and performs the delete correctly. So the form has no data using the hidden values I guess. Is there anything else I could try.
