After playing around with https://battlelog.battlefield.com/ and https://github.com/
I noticed it does not reload the page when changing the path. The incredible fit is that it does not use the hashtag unlike Facebook and Twitter.
So, how does it do it?
look into History.js and the push state options it supports. It's a very robust library.

I am trying to create a small frame on my site that will show the home page of another site similar to what google is doing with your most viewed pages. I know how to create this with frames but I am really against frames in general for many reasons not worth mentioning. Is there a jQuery plugin somewhere that can do that for me?
For a more visual explanation go here and navigate to 'portfolio'. The current developer is using simple images for what he is doing. I would like those icons to be frames of other sites instead
You want an actual image of a webpage? You'd need something like html2canvas, but that'll be html5 only. There's some methods for doing this in PHP as well, but it's tricky, and I've only heard of this in theory, never actually practiced it myself.
How about this link?

To embed an external page within your page, you should check out the <iframe> tag.
As pointed out in the other answer absolutely the best solution to embedding an external site into yours is usually an <iframe>.
You could, in theory, avoid using <iframe>s by pulling in the HTML from the external sites via ajax requests and injecting it into your page, as appropriate, using javascript. This is a much more heavyweight solution however and I wouldn't recommend it to solve your particular problem, but just to point it out.
What I would recommend however is just linking to the sites, potentially with target="_blank" so that the links don't send the browser away from your portfolio.
<iframe>s have their place for certain solutions, but for browsing the different sites you've worked on? No - I'd say the user would benefit from the full browser window experience for that.
I've noticed many websites (like Hulu.com), have very interesting page transitions. They manage to fade out of a page and into a new one.
How would this be accomplished with jQuery/Javascript. Would I somehow have to link a .js to both web pages? How would I do this?
You could do this with a combination of PushState part of the History API (pjax is an excellent way to add this to an existing site) and jQuery. This is how github handles it (try browsing folders of source code, and look at the URLs). What pjax lets you do is intercept any <a> click before the page redirects, fetch the page that would load via ajax, insert the HTML in your page (which you can control with jQuery animations like fadeIn()) and the update the browser URL so the page can be bookmarked.
No need for a .js reference on both pages, just the page before.
There are many plugins for jQuery that support most transitions.
This looks like a pretty comprehensive list, although 2010 dated.

I am currently working a new feature to allow users to select the thumbnail they would like to use when sharing an page on Facebook. The user should be able to use the Facebook widgets like the send dialog or share buttons as well as simply cutting and pasting the URL into their udpate status dialog on Facebook.
I have read much of the documentation, which seems to indicate that I simply need to add multiple og:image tags in the page being shared. I have done this and run the page through the linter so the cache gets updated.
When passing the page to the share.php directly, effectively removing any of my client side code and letting the dialog present what it is scraping, I am seeing 3 images from the page available.
I am not sure what I am doing wrong here.
Here is the linter result, the graph object, the sharer.php link and the page. Anyone have ideas of what I could be doing incorrectly?
I have confirmed that at least the og:title tag is being respected by the share dialog. I have also tested the size of the images, and included file extensions as suggested below.
I know this works because buzzfeed has the exact functionality I am going for. I have reduced my example down to only the core pieces I think should work. You can find the full source here.
Could it be the XML namespace in the top HTML tag?
In the BuzzFeed article, it's:
xmlns:og="http://opengraphprotocol.org/schema/"
In your page its:
xmlns:og="http://ogp.me/ns#"
On the Buzzfeed article, the content attributes in the og:image links point to named .jpg files, vs your links which do not have a filename/extension at the end.
It may be required to include a filename in the links, especially if it's basing image detection on the file extension.
EG:
Buzzfeed:
<meta property="og:image" content="http://s3-ak.buzzfeed.com/static/campaign_images/webdr02/2013/3/18/11/10-lifechanging-ways-to-make-your-day-more-effici-1-2774-1363621197-4_big.jpg" />
Yours:
<meta property="og:image" content="http://statics.stage3.cheezdev.com/mediumSquare/3845/4AC356E3/1"/>
After some tests, I guess it's a caching issue.
Looks like the sharer is caching the graph, using the og:url as a key, so that different querystrings in the sharer won't bypass the cache, if they do not impact the og:url value.
Obviously, the debug tool don't use such cache.
If I'm right (this is just an insight), you can either wait that the cache entry expires or try with a different og:url. Moreover, to ease the test, keep the new og:url equal to the new page location.
So funny story, I'm a developer at BuzzFeed and came across this while trying to figure out why our share dialogs suddenly stopped showing the thumbnail picker.
It looks like Facebook disabled the functionality. It briefly made a reappearance on 1/14/2014 but they introduced a bug that prevented sharing from any pages with multiple og:image tags defined. (See: https://developers.facebook.com/bugs/1393578360896606/)
They fixed the bug, but as of 1/22/2014 it still looks like the thumbnail picker is disabled.
The Sharer.php script on the Facebook site doesn't support all the OG tags as far as I know. The images are scraped from the page content itself, so if you want your three images to appear on the Sharer.php script, include them in your content.
Sharer.php has been officially deprecated by Facebook, so I wouldn't be surprised if certain functionality does not work with it. While it still works, it was always the simplest option and I'm guessing they never built the link image scraping from the og items into it.
I was able to find this article, which shows one way that you can specify exactly what images are available to the sharer.php share page. You can specify one (or multiple) images to share with a URL structure like the following:
http://www.facebook.com/sharer.php?s=100
&p[url]=http://bit.ly/myelection
&p[images][0]=http://election.gv.my/assets/vote.png
&p[title]=My customized title
&p[summary]=My customized summary
I'm trying to create a web page able to change a site visualization (.css or / and .js) in order to recreate the same live change capability offred by Firebug for Firefox or the Inspector of Chrome.
Here an image to better explain my task:
I have been able to visualize the other site inside my page using the iframe, but unfortunately it is not possible to change its visualization and access its elements due to the "same origin policy".
Is there a way to do this using the iframe or loading the external site inside another element?
Update:
Considering the answers the options should be:
create a php proxy page to load the target site and change visualization on it.
create a browser extention.
I've tried the first, even if it requires to install a web server (xampp), with a simple page calling the function file_get_contents('http://www.site.com');
The page is loaded but unfortunately missed some elements (like images) and it is only a static copy; it is not possible to go further in the site navigation.
Update 2:
Load the entire page via javascript could be the better solution (I don't konw how) if it is possible to live change the code but what about the possibility to interact with this "page copy" and transfer the interaction to the original one?
Scheme:
Explanation:
I've noticed Firebug extention can select and live edit any page element, even if they belong to the iframe which loads an external domain page.
What I'm looking for is a way to act like Firebug, get an element and change its style.
I'm trying to load the site into the iframe beacuse I wanted to create a toolbar above it to select my "visualization styles"; for example a button to makes titles bigger and red.
Anyway I'm open to any other methods suggestions.
Update 3:
I have found an extention for both FireFox and Chrome which is really close to my aim: "Stylish"
This add on allows to live change any site css proprerty and save it in order to reload them every time you'll visit the page.
Now my question is: How can I do the same creating a dedicated page to load and change visualization of a specific site?
FINAL EDIT:
In order to continue this question with a more relevant arguments I decided to ask a new one: create a php proxy page
No. Your solutions may be
to let your own site act as proxy so the same origin policy isn't triggered
to build an extension, which will be browser dependent (Firefox or Chrome) and which will require authorization and installation
I'm not sure if I understand what you want very well, but my feeling to ''trick'' this easier would probably to give very specific height and width to your first site (the iframe) and do a jQuery condition
If ($('body').width() == 500 && $('body').height() == 400 {
$('body').addClass('isiFrame');
}
Then, you only have to do your css .isiFrame .myCoolDivs {....}
You might have to use it on a document ready also, but that could be one way to trick it and since you're not doing it on resize (exepect if somebody's having his screen at this exact width and height at start)
The safer way would probably to create a master session using PHP but I cannot give you an example since it've been to long and echo the body class if the master_session or variable is equal to true
Hope it helped!
If you try to fight Same_origin_policy and try to fight it I am sure you won't get much success their.
Server Side
I would suggest you Handle this on server-side, grab the web-page and apply whatever styling and scripts you want, should be very easy!!
If you use Ruby on rails - Nokogiri gem can help you to parse html. And you can use standard library to 'get' a webpage.
Client Side
If you want to do this on client side, you need to write some jquery/javascript code, you can take following steps:
Get the webpage you want to display.
Grab the element's which include js/css files, remove them and your own.
Display the page in new Iframe present in your page.
I would like to know if it's possible to change the contents of the URL in the browser without reloading the page?
I use jQuery and Ajax to load new parts of my page. When I choose "product one", the direct link would be mysite.com/product1 and for "product two" would be mysite.com/product2, but I don't want to reload the site to these pages.
its now possible with HTML_5..
chack this link... http://www.spoiledmilk.dk/blog/?p=1922
also facebook and google using this tric beside Hash(#) attribute
You will have to add hash # if you want to prevent page from reloading.
The css-tricks.com has an excellent screencast on that, have a look at:
Best Practices with Dynamic Content
just use this one
window.history.pushState("object or string", "Title", "/new-url");
This is possible in HTML5. See a demo here.
You can change the URL to another URL within the same domain, but can not change the domain for security reasons.
See the history interface in HTML5 specification for details.
You CAN do that. Though likely you'll need a modern browser. Have a look at this page: http://www.20thingsilearned.com/ created by the Google Chrome team (I used Chrome 9 to read it). Changing pages doesn't reload the entire web page, but changes the URL.
Yes, it is possible using the HTML5 History API. Check this page and this example
You can't. Only if you change the hash, like sAc told you.
But.. May I ask WHY?
