Cross-domain Iframe Communication In Opera?

Feb 11, 2010

I have need to communicate between two iframes of the same domain, which live inside a parent page on a different domain that I have no control over. This is a Facebook app and the basic layout is this
L iframe1 (src='')
L iframe2 (src='')

I need frame1 to talk to frame2, but in Opera I can't access window.parent. frames['frame2'] to do the usual cross-domain methods (updating location.hash for example) Is there an alternate way to accomplish this in Opera?

Fixing Communication Between JS And PHP?

Jul 28, 2011

I need to fix the communication between the JS located in this page and the PHP form script. When the form is submitted I want the page to automatically update which is already present in the script, thanking the user for the submission. Since the PHP script was changed that communication is broken and I hope to get it communicating once again.

Server Communication Without Page Reload?

Jul 23, 2005

I'm trying to find a way to have a script communicate with a server
without having to load a new page. The idea is to have the server act
as a simple wrapper for a database, letting the client do that icky UI

I tried the obvious, putting a frame somewhere it doesn't insult the
eye, changing its location, then accessing the new content via DOM.
What I get from IE (6) for my pains is just a rude "permission
denied". This even though I entered "localhost" as a trusted site in
IE's security setting. What's amiss?

Communication Between Java Applet And Javascript

Jul 20, 2005

let's me explains my long problem:

I'm doing an intranet with a media part. So im must be able to upload files on
a ftp server AND have a record of informations about this file and meta date in
a MySQL database, shown in a php page.

So the first thing i was doing was:

1/ * A HTML Form, with a <input type="file"> which was uploading the file to
the web server. And then, in the next action-php-page, using ftp functions from
php to upload to the ftp server. But this make upload the file 2 times, which
slow, and the user can't do anythig except waiting in front of a blanck loading

=> no way

(BTW, the site admin refuse that the ftp server and the web server to be the
same computer)

So i tried something else:

2/ * A HTML form, the user enter meta data about the media, click next, and
then, a php page which loads a java applet an pass informations to it (by param
The applet have a browse button, and a go button, which start the transfert
(JDK 1.4.1) trough the URLConnection. The file is uploaded once, and there is a
progress bar, which is wonderful.

But now, i need the src_file information wich is the java applet. So i have two

A/ I make a post to the webserver from the applet. But i'm using session
identification (needed for tracing users actions) and i'm gonna use SSL in less
than one month, so i think it would be complicated.

B/ I export the information from the java applet to javascript, and then to
HTML hidden field, so that the user can submit the full-hidden-filled form. But
i can't make LiveConnect works.

i'm under Mac OS X 10.2 (jaguar) so i need to make work LiveConnect on both
Safari 1.0 (v85.6), mozilla 1.5, and Mac OS IE (5.2).

AJAX :: Intermittent Communication Failures

Jan 29, 2011

I have a web app with a game and chat updating with ajax very frequently sending thousands of XHR requests to the server during a user's session. The problem is that most clients experience intermittent connection failures or timeouts. On the server it appears to be fine, all requests are logged to have completed successfully and on time but the client gets either a communication failure or a timeout. This makes the user feel like the game or chat just got stuck.

I use YUI for making the XHR calls but I replaced that with jQuery with exact same results. I make sure that only one query is active at a time, so I am sure that I am not hitting the max 2 connections problem. The failure rate may be 1 in 200 hundred requests or something but it seems that when a client has a failure then it fails at a higher rate, say 1 in 10 until the problem goes away. I have clients send back an error request when such errors happen in order to track the problem. I have tried various things to try to figure out what is wrong but I have not found anything. I don't think that it's the client's connection as it happens to a sizable portion of my users, it doesn't look like it's the server either.

So what I am wondering is whether this failure rate is common or expected when doing heavy ajax staff and I need to find a way to work around it or this must be a problem in my system that I need to figure out. If the latter any pointers where to look at?

Back - Forward Browser Button For Iframe - Bring Back/forward Iframe Or Top Window?

Jan 24, 2011

I am wondering how Back, Forward browser button works for iframes. Does it bring back/forward iframe or top window? I remember I had before a problem because I wanted to bring back iframe and not top window as it did. But today I tested my Facebook app and was surprised to see it works as I need which means it brings back/forward iframe window and not top. Is it possible that Facebook has some javascript code which does that or is this normall behaviour?

Prototype.window.js Close "Window" From Iframe?

May 19, 2008

I created a prototype.js/window.js "Window" pseudo window div with another page from the same directory loaded in its iframe I could not put a button/link on the iframe doc that would close it by calling functions in the parent window

I used "window.parent" "parent" alone "top" but the only thing I could access from the iframe was the window.parent.location property I ended up constructing the Window by writing the content to it from the main page, not loading a url in the iframe

But it bugs me that I couldn't access the parent window functions (or anything, getElementById didn't work either, so Window method $('Window_ID').close() wouldn't work either)

New Iframe In Current Window

May 17, 2007

I have a page that contains 3 Iframes.
Left is navigation
Center is main content
Bottom is footer

How would I put together a link from the navigation that allows me to open a NEW Iframe over the existing Center region? I don't want to target the existing Iframe and load the link in that window. I want the existing Center Iframe to remain open and an additional Iframe to open with the new page.

The goal is so that the 2 Iframes are independent. They are both forms and I need them to be able to copy and paste into both forms at the same time without affecting each other.

How To Identify If A Window Is Within An Iframe

Feb 21, 2005

I have jsp1.jsp with an iframe iframe1.jsp within. Once the http session is expired any page is redirected to a logout1.jsp page.

If the iframe1.jsp was loaded and httpsession expired the logout1.jsp is displayed inside the iframe .... but I want it to be displayed on the full screen.

My idea is to check once loading the logout1.jsp if it is inside an iframe and to reload it's parent. I tried following lines within the logout.jsp. It worked well, but caused an infinite loop ...

if (window.parent != null )

I guess it is not the correct way to check if a window is within an iframe...

IFRAME Keeps Popping Out Of Window

Apr 19, 2005

I have an Iframe in my page and it's referencing a database application. Everything works until I choose a selection form that forces a refresh and then the whole iframe pops out of my page and into it's own page.

So if I put iframe source of page1.htm into page2.htm when the refresh happens I just page page1.htm not embedded in page2.htm. It's like it's jumping out of my page.

Open New Window Into Iframe?

Dec 16, 2009

force a page that always wants to open in a new window to open in an iframe?

I have several links on the same page with an iframe to the side, and i would like it for the pages to open in the iframe without ever leaving the main page, so the user could click a link and the page would appear, and the links are still on the side to be able to click a different one. I have it working right now on most pages, but there are a few pages (which i cannot modify the code) that are opening in new windows, and was curious if there was a way to force it into the frame?
