Permission denied to call method XMLHttpRequest.open

[pfarmer]

Hi all,

When I look at tickets in the Staff CP, I get the following javascript errors:

In my JavaScript Console (Firefox 1.0.4):

Error: uncaught exception: Permission denied to call method XMLHttpRequest.open

and this error in IE:

Line: 906
Char: 4
Error: Permission denied
Code: 0
URL: http://secure.hbhosting.co.uk/suppor...icket&ticketid

This happens when I click on any of the following:

Forward,Billing,Add Notes,Release,History,Audit Log, and Edit. General and Post Reply work fine.

Anyone know why I'm getting these errors?


Thanks

What are your security settings? v3 uses a new popular technology called AJAX (Also used in GMail, Google Maps etc).

Are you getting this from the winapp? If so, make sure that the URL is EXACTLY as registered. I had the exact same problem in the winapp with http://support.blah.com not working properly when https://support.blah.com was used in the installation. Check that, it helped mine. Silly, yes, but it worked, at least for me.

I have this same issue and it is working without errors on 5 other computers .. 2 with the exact os etc as I have

this is driving me nuts

.. anybody find a solution to this ?

[caz]

this happens way too often ..
I search for hours .. then finally post to a forum .. and less than an hour later I figure it out

everything here may not be required, but this is what worked for me ..

- uninstalled the winapp
- cleared IE cache/cookies/history
- emptied the cache directory of supportsuite install
- reinstalled supportsuite

This was something else I found browsing the forums .. mine was correct originally but this may help someone else having probs.

- your URL in the winapp must be exactly as it is in the admin cp > settings > general

ie:
if it is http://www.domain.tld/help then the www has to be there in the winapp
and if it is http://domain.tld/help, then the you must leave the www out of your winapp URL definition

Does anyone have a rock solid solution to this? It is madness.

What is winapp?

Permission denied to call method XMLHttpRequest.open

This is caused by an un-signed script in a Mozzila based browser.

Great find, Martin. Could someone from Kayako reading this please make sure this fix gets into the product ASAP? Our only sanctioned browser is FireFox and I can't justify running Internet Explorer just for this application.

AJAX etc, it great new "technology" to be used, but neither Gmail or Google Maps requires me to alter my browsers security settings to work!!

Add your site to your Trusted Sites in Internet Explorer, delete all temp internet files, and refresh the page. You should be fine for the permissions denied issue. Just figured it out myself.

Hey guys,

I've read through the whole topic, and I don't understand why I can easyly read my emails via Gmail, which is in Ajax, and still not be able to run any XMLHttpRequest on my computer (localhost, with EasyPHP).

Anyone has a real solution?

I read about the certificate, but this only works for java applets i guess.

My script is a javascript in an HTML page.

when I run it under IE, I just have to say 'yes" to the security alert. Firefox simply throw me an 'access denied for XMLHttpRequest.open"

Please ! If there is someone out there with a solution, he/she would be welcome !

niX.

All you need to do is create a server side script that fetches the data you want, and returns it to your client side javascript. Because the server script resides on your server, and in your website, there is no security issue.

I'm an ASP developer, not PHP, so the only example I can give you is ASP based. Hopefully you can make a translation though.

An example line in your client script might be:

xmlhttp = new XMLHttpRequest();
xmlhttp.open("GET", "/proxy_fetch.asp?url="+url, true);

The URL above is your server side script that actually retrieves the data you want, and writes it back in the response:

<% 
Response.Expires = -1
Response.Buffer=True 
Dim MyConnection, TheURL
	
' Specifying the URL
TheURL = request("url")
	
 Set MyConnection = Server.CreateObject("Microsoft.XMLHTTP")
' Connecting to the URL
MyConnection.Open "GET", TheURL, False
		
' Sending and getting data
MyConnection.Send 
TheData = MyConnection.responseText

'Set the appropriate content type
Response.ContentType = MyConnection.getResponseHeader("Content-Type")
Response.Write (TheData)

MyConnection.Close
Set MyConnection = Nothing
%>

From this point forwards in your client script - just carry on as normal.

I hope that makes sense? Try it - it's a lot simpler than you might think and it completely bypasses any security issues because your client script never attempts to access data outside of your server - only your server script does.

Good luck!

Hello,

This is my first time in, but I too have been trying to get rid of this Permission Denied error on the open call. I am also an ASP developer and did try to incorporate your code. I am trying to send XML data to a remote server and then retrieve the XML result.
For now I have my XML data hard-coded. I've been just trying to play with the XMLHTTP object to get this to work. Things were going fine locally, but as soon as I enter the remote server location, I get the "Permission Denied" error.
I'm unable to see if your code has fixed my problem. I'm getting to results back. Something happens, but it doesn't appear to execute my Server Script.

My Client code is simply a javascript call to:
xmlhttp.open("GET", "ServerScript.asp?url="+"http://<remoteurl>/engine/GCMRequest", false);

My Server Script is as follows. I basically took your code and change the "POST" and added a big long XML string to send (which I exlcluded here).

Response.Write "in here"
TheURL = request("url")
Set MyConnection = Server.CreateObject("Microsoft.XMLHTTP")
MyConnection.Open "POST", TheURL, false
MyConnection.Send("XMLRequestDocument=" & strXML);
TheData = MyConnection.responseText
Response.ContentType = MyConnection.getResponseHeader("Content-Type")
Response.Write (TheData)
MyConnection.close
Set MyConnection = Nothing
%>

But I am getting nothing back.
Do you have a minute to look at this and tell me if you see something wrong?

Thanks!

I was able to get this client/server code to work.
A stupid javascript error was keeping my code from proceeding and was not reporting an error.

Thanks for the code though! It was a life saver!!
