Basically I want to replicate the page changing effect found here, at http://timvandamme.com/
But instead of using #values I want to use PHP includes, mainly because I want the site to be as uber-seo-friendly as possible... but still have this nice effect.
So is there a way of doing this? I have a main index file which includes other php files in the centre using the usual 'GET' method, so my pages look like: "index.php?page=about"
In my jQuery code I want to have a declaration where if I click the navigation, the content scrolls up, then once the relevant PHP file has loaded, have the content scroll back down and show the new page content (whilst also of navigated to the new page in the address bar, so if the user clicks the back button in their browser, they return to the previous page).
I know how to code the scrolling bits, it's just literally the ajax loading includes / page navigation parts I'm struggling to work out :\
Any help would be MUCH appreciated! Thanks in advance.
Use standard links in your navigation. In your onClick function, use event.preventDefault() to prevent the pages from redirecting your actual users (but they still appear as normal links to search engines).
Foo
<script>$("a").click(function(event){
event.preventDefault();
navigate($(this).attr('href'));
});</script>
Use the onClick function of the links to change the page's content with AJAX (just like it appears on the site you linked), but additionally set up each "page" (using error documents, mod_rewrite or something) to display its content, but allow navigation in this same way. By doing so, you will have the same functionality with the search-friendliness you desire.
To add to the others, some search engines understand this problem and offer site map utilities. You can check out google's site map solutions here:
http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=156184
The site map will allow you to explicitly inform google about certain uri's (like http://timvandamme.com/#about).

I'm implementing my first website, mainly consisting of one page, that loads its content via ajax. To differentiate the content in the address bar I use the History API of HTML5 to change it according to the content shown. There is no problem with that. So if I go to "www.mysite.com" it shows my landing page. If I then click on a nav item like "contact", it loads the requested content into the page and changes the address bar to "www.mysite.com/contact". Back and forth navigation in the browser does work, as long as I don't leave the page completely. Directly entering "www.mysite.com/contact" in the address bar gives me a 404 page not found.
Why is that so and what can I do about it? I want visitors to have the possibility to store bookmarks to that specific content they are on, but right now, they can only bookmark the landing page and have to navigate from there.
Is there a way, to always call my index.php from every path, that contains my domain and can call the content per ajax onload? Are there better/more correct ways? Is there any vocabulary that might be interesting for me?
Please no suggestions to fancy frameworks! I try to stick with html, js, php, css, apache, mysql to understand the underlying concepts before advancing to jquery, zend etc.
thanks in advance!
(I use Apache 2.4.27 with PHP 5.6.31)
What has been known for a while, is that a "fast navigation" works easily for http://example.com/#1 --> http://example.com/#2.
However, there is a new technique out there. It enables fast navigation between http://example.com/1 --> http://example.com/2.
EXAMPLE: http://rageslide.com/
As you can see in the example, the navigation between http://rageslide.com/1 and http://rageslide.com/2 etc. via swiping apparantly DOES NOT FORCE THE ENTIRE SITE TO RELOAD.
I'd like to do the same for my site, but I have no idea how to do this. All pages served by my site are dynamic (via PHP and MYSQL).
I have this idea:
Cache the generated output of a page (http://example.com/2) for 60 seconds.
When the user is on http://example.com/1 preload (http://example.com/2) via Javascript.
The user navigates from http://example.com/1 to http://example.com/2. Since the content is preloaded and cached, the content will be served to the user instantly.
Different idea:
Somehow, http://example.com/1 is being interpreted as http://example.com/content.php#1 through a .htaccess. But I have no idea if this is possible or not.
Will this work? Or what would be the best way to solve this problem?
No, the url you see there is not used to load another page. There are AJAX requests in the javascript code contained in the website, that load the new content to display and update the URL bar.
You can read more about it in this article and in the following questions asked in the past:
Modify the URL without reloading the page
Updating address bar with new URL without hash or reloading the page
i can think of two possible thing you can try out.
first is simply use iframes to load the next and previous page of each page, and when someone swipes to the next page load the next page to a new iframe or a div with ajax or any other html element for that matter.
the other is to use the rel attribute, here is an explanation about it.
hope this helps you out
you can get pretty close without scripting anything or degrading the site by letting the browser cache the expected navigation point resources
for caching images, put dummies at the end of the body
<img .... height="0" width="0">
and for pages
<link rel=”prefetch” href=”url” /> there is also a rel attribute for next and previous for slide viewer type pages
Note: the url can be a javascript resource
Note2: the transition may be slightly less clean than dynamically populating from javascript especially on larger complex pages, but will still work with noscript or javascript turned off, so maybe a good fallback
As some of you may know, Google is now crawling AJAX. The implementation is by far something elegant, but at least it still applies to Yahoo and Bing AFAIK.
Context: My site is driven by Wordpress & HTML5. An Custom Post Type has tree types of content, and the contents of these are driven by AJAX. The solution I came for not using hashbangs (#!) until fully understand how to implement them is rather "risqué". Every link as HREF linking to *site.com/article-one/?tab=first_tab*, that shows only the contents of the selected tab (<div>Content...</div>). Like this:
This First Tab
As you may note, data-tab is the value that JavaScript sends with AJAX Get, that gets the related content and renders inside a container. At the other side, the server gets the variable and does a <?php get_template_part('tab-first-tab'); ?> to deliver the content.
About the risqué, well, I can see that Google and other search engines will fetch *http://site.com/article-one/?tab=first_tab* instead of http://site.com/article-one/, making users come to that URL instead of showing the home page with the tab content selected automatically.
The problem now is the implementation to avoid that.
Hashbang: From what I learned, I should do this.
HREF should become site.com/article-one/#!first-tab
JS should extract the "first-tab" of the href and pass it out to $_GET (just for the sake of not using "data-tab").
JS should change the URL to site.com/article-one/#!first-tab
JS should detect if the URL has #!first-tab, and show the selected tab instead of the default one.
Now, for the server-side implementation, here is where I'm kind lost in the woods.
How Wordpress will handle site.com/article-one/?_escaped_fragment_=first-tab?
Do I have to change something in .htaccess?
What should have the HTML snapshot? My guess is all the site, but with the requested tab showing, instead of showing only the content.
I think that I can separate what Wordpress will handle when it detects the _escaped_fragment_. If is requested, like by Google, it will show all the content plus the selected content, and if not, it's because AJAX is requesting it and will show only the content. That should be right?
I'm gonna talk third person.
Since this has no responses, I have a good one why you should not do this. Yes, the same reason why Twitter banged them:
http://danwebb.net/2011/5/28/it-is-about-the-hashbangs
Instead of doing hashbangs, you should make normal URIs. For example, an article with summary tab on should be "site.com/article/summary", and if it is the default one that pops out (or is it already requested) it also should change to that URI using pushState().
If the user selects the tab "exercises", the URL should change to "site.com/article/exercises" using pushState() while the site loads the content throught AJAX, and while you still maintain the original href to "site.com/article/exercises". Without JavaScript the user should still see the content - not only the content, the whole page with the tab selected.
For that to work, some editing to the .htaccess to handle the /[tab] in the URL should be done.
my question is about this website - http://www.bits-apogee.org/2011/
whenever you click on the link in the side navigation bar, the middle part of the website is dynamically loaded. Also, the url also changes, everything else remains unchanged. how is this done?
is this some query plugin?
I totally agree with #JMCCreative. It looks like it's an actual refresh. You should look at the following post on StackOverflow.
Modify the URL without reloading the page
The site is using Hashes (#) in the URL to denote the new content being loaded.
This is useful for people bookmarking dynamically loaded content (normally hashes load to specific areas on a page, named anchors or ID's for new browsers), because they don't trigger the page to refresh...
http://www.highrankings.com/urls-with-hashtags-307 there are drawback (SEO) concerns to this... however you will notice more and more sites doing it so i would assume the SEO robots will get better.
There are 2 possibilities:
You can use the HTML5 capabilities to change the url (history pushState), however this feature isn't available in all browsers yet. For more information, look at this SO post: Is there a way to change the browser's address bar without refreshing the page? .
You can use a hashtag (#) part as fall back for browsers who don't have above feature yet.
If you use jQuery, you can use the handy plug-in jQuery Address. This will take care of both above cases.
They're not using a plugin. They're doing an ajax request to a URL like this:
http://www.bits-apogee.org/2011/getcontent/?even=Rachel+Armstrong
and dumping the overview in the container.
The circle of this type of process is usually like this:
listen for link clicks
on click, prevent default on event.
user window.history.pushState to update url
some other code - hears new history
generates a url to get the content.
ajax load the url
dump the data into a container
2 Libraries I have used, both are easier than the above, as they rely on loading a regular html page via AJAX instead the example site you point to, which used a JSON format to get the data.
Pjax - update peices of the page, by pulling that HTML node from a different URL.
Ajaxify - easiest solution, you could do that effect on an HTML site in 10 minutes.
Here's the situation.
I have a site where clicking hyperlinks within a certain div makes a jQuery function get the content of a div from a separate page. Because of this, the URL don't change. I need it to change as well as writing an entry in history.
My pages are setup like this (not sure this is the smartest way of going though)
access.php (main logon)
new-user.php
forgot-pass.php
index.php
controlpanel.php
etcetc. Now, all of these pages are reachable on their own and are mainly identical and all contain a div called "container". When clicking links, the content from this div gets erased and the content from the coresponding div (container) gets loaded from the file of the URL (href). I'm terrible at explaining..
So basically, what I need is some javascript that picks up the href link address and just pastes it in the url bar at the same time as it creates an entry in history so the back and forth buttons work.
I plan on extending this in a while as well, translating query strings as well. But there are a few constant static pages I need to take care of first. Any help would be very appreciated! :)
You are not allowed to change the entire URL by JavaScript but you can use URL hashes. I recommend you the browser history plug-in. You can simply register a handler to react on URL changes and load your corresponding content via ajax.
Have you looked at the jquery address plugin? Look at the examples. Is this similar to what you want?
It's not possible with "normal urls" (we must wait for a new generation of browsers...)
But there is a "trick": playing with anchors.
A link like "same_page.php#anchor" does not reload the page, but act on both the history and the adress bar.
So, if instead of having url like "page.php?param=lorem", you could have "page.php#param=lorem", you have your solution :)
