I have to use an embedded search engine in my website which it has it's own style.Now i would like to change just the back-color of table which is presenting in my website. Can you please let me know if this is possible or not?
I already tried adding some style to the header of my page but the link still following the style from original stylesheet.
Thanks
That's not possible if the embedded page isn't served by the same domain (including port).
That's a security restriction.
If you want this kind of interaction, you'll need to have some control of the server of the embedded page in order to set permissions : https://developer.mozilla.org/en/http_access_control
Another (rogue) solution is to fetch the page server-side and to embed it directly in your page.

I've been googling and looking at various options but could not seem to be able to find a perfect solution that works in what I'm attempting...so needing some help here.
The situation/environment that I have is the following:
Parent page (which has the iframe) - is on a different domain, and the only control I have is a portion of the body tag, where it is updated via an admin console using html/WYSIWG editor. No access to head tag or even hosting jscript in their domain.
Child page (iframe) - is hosted in our domain, and we have full control.
The parent site is actually 3rd party online stores where we have products there, and we want to put in common information that we can control on our end without having to edit each individual product listing one by one.
I've tried alot of options found but it does not seem to work as either they need to include in js file or access to the head tag in the parent page.
So wondering if there are any other options that can help us on this?
I'm afraid you need access to JavaScript on both domains to do this.
Could you get the 3rd online store to host a small JS library that all their clients could then use to solve this problem? I work on a project that allows third parties to add in iFrames and produced this little project for just this reason. When any one say they want to be able have their iFrame resize to content, we point to the iFrame js file and say include this on your page.

Sorry, that's not quite the answer your after, but trying asking the store to support this and they might be open to the idea, as I expect others have the same issue with their site.
I want to allow some websites to embed an iframe with a page from my domain. However, I don't want anybody to be able to use the iframe content without my permissions. How can I allow only domains of my choice to be able to embed the iframe with the page's content?
I know vimeo does this, and allows video owners to block the video on certain websites that they don't find appropriate.
I want server side ASP.NET solution, because Javascript code can be altered. However if it can be done using javascript code and its secure, It's ok.
From what I've seen, I need to pass the referrer in some way, but in a way that can be manually altered by other website owners to include the iframe themselves and it would work on their website too, without a permission.
Since it will be a standalone page as you mentioned in the comments, you can do this by inspecting the referer property.
Request.UrlReferrer
See that it contains the domain that you want to allow. This property is available when an embedder puts your page in the IFRAME's SRC attribute and the page loads for the first time.
If the user clicks on a link inside the IFRAME, it is not guaranteed to pass the containing page as a referrer.
If you want to allow multiple linked pages inside the IFRAME to allow a specific domain, then you will need to stick to a JavaScript based solution.
Note however that neither method is completely foolproof.
In the html, there's one iframe loading external page from different domain. And I cant change the source code of this external page.
Now I want to inject some html codes into the iframe, such as adding one link in the external page.
What's the possible way for me to do that?
I tried to use contentWindow.document, but getting permission issue.
Any help will be appreciated.
I think this is not possible. however if you want to do this at any cost, you can download the required page using server side like file_get_contents('http://www.google.com'); in php. and make changes to it, save it in a file on your server and then open it in iframe you want to.
Anyone who has a good idea, how to add additional styles to an facebook iframe?
Whats wrong with CSS you can add link to an external sheet on each tab
Check out this question about applying css to an iFrame. If the iframe content is on a different domain, like what happens in the case of Facebook iFrame content on your site, you have no control over it due to cross site restrictions. Some older Facebook plugins allow to you specify a stylesheet on your server that they download and import to their server, but most of their newer plugins to not allow for this. Also, their terms of service often state you cannot attempt to the modify their iframe content embeded on your site.
I want to make a site where there user can basically navigate the web from within an iframe. The catch is that I'd like to be able to have more control over what is rendered within the iframe. Specifically,
I'd like to be able to filter out images or text, disable forms etc.
I'd also like to be able to gather feedback such as what links the users clicked on.
Question 1:
Is this even possible using a standard back-end scripting language (like php), with html and javascript on the frontend?
Question 2:
Would I first need to grab the source of the site before it is rendered, then do whatever manipulation is necessary, and finally re-render it somehow?
Question 3:
Could somebody please explain the programming flow that would occur here (assuming its possible)?
I think you would probably want to grab the source of the of site (with server-side code) before rendering it. You might run into cross-site scripting issues if you try to use JavaScript. Your iframe would load a page like render.php and pass the address of the page to render os a querystring parameter. Then use regular expressions to find elements in the HTML that render.php downloads from the address. Rewrite the HTML as necessary and then write it all out to the iframe.
Rewrite links so that that the user is taken to a page you control and redirected onto a target site if you want to track where people are going. Example: a link in the page needs to go to google.com. You would send them to tracker.php?target=http://google.com. You control tracker.php and can log each load of this page and then redirect the user to the target site.
Update:
Another possible solution is to use Apache or other server to proxy the target website. There are modules like mod_proxy for this. There may also be modules that let you parse the HTML or you could roll your own.
I should point out that even the best solutions offered to your question will be somewhat brittle if you do not have full control over the target site. You will want to have lots of error handling or alerting.
You can have a look at this. It uses iFrame really well, and maybe even use the library it has.
