I get the feeling that this is impossible, but is there a way to change what the url of my page will be if someone bookmarks it.
I ask because I'm running something in an Iframe, which isn't reflected in my URI. I was thinking maybe I could keep track of where the Iframe is in javascript, and then if they try to bookmark the page, I can put that JS into the URI they bookmark.
Is this possible?
You could always create clickable "bookmark this" links you could change dynamically depending on whatever logic your iframe setup uses. That won't deal with traditional bookmarks (user clicks the star in FF, adds to favorites in IE).
For anything better than this, please post a more detailed explanation of what you are doing with the iframe, and the calling page.
In short: no. Bookmark creation doesn't trigger a Javascript callback outside of rare cases like Firefox extensions.
If you want to insure that all your page content is available in a bookmarked version of the page, you'll need to add all the relevant state to the page URL. This could take the form of a session ID, encoded URL of the iframe content, or some other identifier, but it should be a unique, durable location, or else the bookmark will break eventually.

I'm working in writing a chrome extension, and as a result I have the peculiar situation of using non-cross domain Iframes, without the ability to alter the page being displayed in the frame.
When a user clicks a certain link, in he iframe, I want to run some JavaScript. The default behavior for clicking that link is to load page targetpage.com. I don't think it's possible, or easy, to read listen for a particular element being clicked inside an iframe
As a workaround, I figure I can check if the iframe reloads, pointing to targetpage.com, and then perform the action.
Note: the action is entirely in the parent page, let's imagine I'm just trying to trigger an alert box.
I know how to trigger JavaScript when an iframe loads. My three questions are:
1) how can I check the url of an iframe?
2) is there a way to check the iframe, url prior to targetpage.com being loaded. Esther than after?
3) is there a better solution?
You could listen to webNavigation.onBeforeNavigate in background page, it fires when a navigation is about to occur, and you could get url and frameId in the callback parameter.
This may not be the best answer because I haven't played around with this much.
Chrome has a webNavigation API that looks to be something which may come in handy for your extension.
However if you want to get the current domain you're on you'd use...
document.domain
If you're in a subdirectory of that domain you can grab that with...
window.location
It also works with an added hash to the url.
If you want the url without the hash you could use document.referrer or if you feel hacky you could do something like...
var str = window.location
var res = str.toString().split(str.hash)
document.body.innerHTML = res
the requeirment is that I want to avoid the specific web page to save to bookmark,
and is there someway to acheive this funcion just use some code, maybe add or js code . thanks
The answer is no, the user can always bookmark a page as this is browser function, but you can use sessions. Then make sure that any request for a page
must have an active session id or it returns an error or redirects to the home page. The user can bookmark the page but the bookmarks will then only work for a short time (until the session expires). This also has the added benefit of
making the site impossible to index by search engines.
The closest you're going to get is if you open another window using JavaScript as you can control whether the menubar and toolbar are displayed.
window.open(
"https://www.google.com/",
"Google",
"resizable,scrollbars,status");
However, this is likely going to be blocked by their popup blocker.
I have index page that contains items i want to keep on all the pages. And i have iframe in the middle of the index page, where all the content is shown.
<iframe id="midfr" src="news.html"></iframe>
When clicking on links, content goes to midfr, while website url is always like www.example.com/
Is there a way to have urls like www.example.com/iframe_url/ when going to specified page using iframes? I dont even have a clue on how to do that.
However ive seen some websites that have some constant divs, while main content blinks on visiting links. Although their source code didnt include any iframes..
No, because iframes don't provide any events to the DOM that you can use to change the URL.
Even if your write it as a method to capture and execute the event. You will still not get it. Because it is not allowed.
Iframe won't provide control over any event, untill the code to handle the event is already a part of it.
You can change the Website's URL using History PushState method. But only if you can have an event to do that. Since iframes don't provide you with an event you won't be able to change the URL.
On lifehacker.com when a user clicks a article on the right menu sidebar, the article & the page url changes, but the #rightcontainer always stays visible and , you never see it blink on the change of the page url, and when the article is ajaxed in (this is easy),
How would you change the page URL with a DIV staying visible on the page the whole time.
How is this possible? Javascript of some sort? (I think its freezing the browser then doing something, getting the data ready? )
I always thought you couldn't change the page url with javascript because of security issues.
I think you are looking for State Handling :)
It used to be done by adding # at the end of the URL, but now HTML5's State Handling features allow us to change the URL completely (ofc, within our domain)
The answer you need is located here:
https://github.com/browserstate/History.js/
Each url can include the same source as right container it won't refresh/blink as in browser cache.

A link can be followed via JavaScript if you require, its not regarded as bad practice (afaik). But there is no need to use javascript it could just be normal anchor/href.
OK, so here is my issue. I'm building a system which will allow people to embed lists of links on their pages. When the link is clicked, i'd like to use something like Lightview or Lightwindow to open it up over the whole window, not just in the iframe.
I don't have access to the page that the user will be embedding this object into. Everything I've tried so far tells me that I can't open anything over the parent window, since I don't have access to it from the iframe or object, javacript security issue.
However, I've seen sites that do that kind of overlay. so it must be possible. If anyone can point me to any resources that could help, that would be great.
if it matters, i'm using Ruby on Rails...
Thanks...chris
It can't be done if the iframe is from another domain than the website, because:
You cannot change the dimensions of
the iframe from within it.
You cannot access the parent
document from within the iframe.
I suggest trying using some sort of JS file people will embed in they're website, in the place they want your links to be (something like Google Ads) and do a document.write to place
your links in their webpage. then, you will have access to the page, and can do a whole lot more :)
is this helping you?
As vsync said, you will have to have the user embed a script instead of the plain HTML.
This script has full control of the page, and if you also want it to be able to communicate with the framed document (your site), then you could use something like easyxdm to do cross document communication.
