Alternate methods to document.write

ErrolDC2 · Oct 14, 2005

Hi. I'm trying to work around a problem and I was hoping to get some input from folks who are a bit more knowledgeable then me in this regard.

I have an application that some people in my company access via WebVPN, a service on the Cisco VPN concentrators.
A portion of this application uses js to do some stuff. One particualar element of this "stuff" writes some html into a pop-up window with document.write, but my vpn concentrator replaces document.write with webvpn_document_write and I think this is a known bug so I'm trying to work around the bug.

Here is the original code, as it sits on the server.

Code:

function signHandler(result){
	if (result != "OK") return;
	self.frames['submitFrame'].document.open("text/html");
	self.frames['submitFrame'].document.write("<html><body><form id='signForm' method='post' action='/DeltekTC/TimeCollection.msv'>" +
		"<input type='hidden' name='unit' value='TsSign'>" +
		"<input type='hidden' name='event' value='open'>" +
		"</form></body></html>");
	
	self.frames['submitFrame'].document.close();
	var signForm = self.frames['submitFrame'].document.getElementById('signForm');   
	top.setFormSubmitted();
	signForm.submit();

This is what it looks like when the concentrator mangles it.

Code:

function signHandler(result){
if (result != "OK") return;
self.frames['submitFrame'].document.webvpn_document_write=function(){
self.frames['submitFrame'].document.write()
}
self.frames['submitFrame'].document.open("text/html");
self.frames['submitFrame'].webvpn_document_write("<html><body><form id='signForm' method='post' action='/DeltekTC/TimeCollection.msv'>"+
"<input type='hidden' name='unit' value='TsSign'>"+
"<input type='hidden' name='event' value='open'>"+
"</form></body></html>",document);

self.frames['submitFrame'].document.close();
var signForm = self.frames['submitFrame'].document.getElementById('signForm');
top.setFormSubmitted();
signForm.submit();
}

Does anyone have any suggestions?

One correction the

Code:

self.frames['submitFrame'].document.webvpn_document_write=function(){
		self.frames['submitFrame'].document.write()
	}

is what we added to try and get around this issue. No luck obviously

perhaps try innerHTML?

Code:

function signHandler(result){
    if (result != "OK") return;
    
    self.frames['submitFrame'].document.body.innerHTML = 
    		"<form id='signForm' method='post' action='/DeltekTC/TimeCollection.msv'>" +
        "<input type='hidden' name='unit' value='TsSign'>" +
        "<input type='hidden' name='event' value='open'>" +
        "</form>";
    
    var signForm = self.frames['submitFrame'].document.getElementById('signForm');   
    top.setFormSubmitted();
    signForm.submit();
