I am using a script for Ajax from Dynamic Drive on my site to load content into my div. It has worked great for me until I created a page where I want links. For some reason I am finding that if I create a page with a single link, the page will not load. I can click on it all I want and the page still will not load. If I have a page that is just purely text content, it loads. Is this a flaw with Ajax, or am I not doing something right? My intention with my site is to have a "Store" section so I can use Amazon Affiliates. I can't even get my page to load even if I have a simple link say pointing to Amazon.com. Unfortunately this Ajax script has been the only successful way I've been able to get my content to load into my main div. For some odd reason links in the links section on my site will appear and that page will load, but not for my "store" page.
My site is: http://veterinarycare.atspace.cc
I'm not asking for a direct code, but just a step in the right direction.
'store.html' gives a 404 Not found... Does this file exist? That is probably your problem... Your links.html page for example has a link to ASPCA and that works fine.
You may also want to look into jQuery, as this is a bit neater for doing ajax and other javascript effects. You could probably get all that javascript mumbo jumbo down to 5 lines or so...
Also remember that your site isn't going to be particularly google friendly with all the content being loaded in via javascript.

I was reading up on ajax and how it empowers us to exchange data with a server behind the scenes and consequently avoid full page reloads. My confusion lies here, I don't really understand what full-page reloads mean. I think it's probably cause I've been working with ajax/react since the start I guess and have not really seen any webpage of mine fully reload when I access stuff from a database or an api.
It'd be great if someone could explain what they are and why did we need them before ajax?
A full page load is where the entire page is downloaded from the server. A page typically consists of several sections: header, footer, navigation, and content. In a classic web application without AJAX, a user clicks on a link to another page, and has to download the full page, even though only the main content is changing. The header, footer, and navigation all get downloaded again even though they don't change.
With AJAX there is the opportunity to only change the parts of the page that will change. When a user clicks on the link, JavaScript loads just the content for that link and inserts it into the current page. The header, footer, and navigation don't need to reload.
This introduces other problems that need attention.
When AJAX inserts new content into the page, the URL doesn't change. That makes it difficult for users to bookmark or link to specific content. Well written AJAX applications use history.pushState() to update the URL when loading content via AJAX.
There are then two paths to get to every piece of content. Users can either load the URL containing that content directly, or load the content into some other page by following a link. Web developers need to test and ensure both work.
Search engines have trouble crawling AJAX powered sites. For best compatibility, you need to employ server side rendering (SSR) or pre-rendering to serve initial content on a page load that doesn't require JavaScript.
Even for Googlebot (which executes JavaScript) care must be taken to make an AJAX powered site crawlable. Googlebot doesn't simulate user actions like clicking, scrolling, hovering, or moving the mouse.
Content needs to appear on page load without any user interaction
You must use <a href=...> links for navigation so that Googlebot can find other pages by scanning the document object model (DOM). For users, JavaScript can intercept clicks on those links and prevent a full page load by using return false from the onclick handler or event.preventDefault() in the click handler.
I am trying to figure out why my website's posts and pages such as my resume are getting a "Complete" status with a green check mark (seemingly no errors or redirects) when fetching and rendering as google, but all of them "render" and look like my homepage. The page speed insights tool seems to be using the same rendering engine as it seems to have the same issue.
Notes:
The html served from my website on initial page load is the correct HTML and content. No redirects occur. The initial page load does not fetch content via JS. I mention this because although my website is not a one page application (I'm using Wordpress), I do use ajax in combination with a post variable flag to fetch new page content when the user navigates to the next page (after the initial page load).
I have verified that all of my pages have been indexed using the "site:" trick in Google search. They are indexed properly, but they aren't "rendering" properly.
Should I be worried? Should I just ignore that the pages aren't rendering properly? It doesn't make any sense. Is anyone else having this issue?
Your resume page has a response type of content-type image/gif so google thinks that the page is an image??
I am developing a web app/message board in AJAX. Ive come to the part where I need to decide how to display threads.
Should I refresh a completely new page for each thread? Or load it via AJAX. Obviously, I want each thread to be crawlable, linkable, and saveable as a favorite in your browser.
Then I saw USAToday's website (www.usatoday.com/news). Its very interesting how they load the page through a popup window, change the URI, and keep the data in the background.
This is exactly what I want, but I don't know what they are doing.
Can anyone else decipher this or lead me down the right path?
My impeccable googling skills has led me to believe that the answer lies in pushState.
http://www.seomoz.org/blog/create-crawlable-link-friendly-ajax-websites-using-pushstate
Essentially, it appears they are...
using the HREF of the provided link to change the URI via pushState.
using AJAX to load the contents of the page accessed via the link.
on close, they most likely use data from the newly loaded page to figure out what section its was under(sports, entertainment, etc), and reload that page.
I am coding a website for a client and they requested that because they have so many sidebar pages under one parent, that when the page link is clicked, it loads in the same area every time without the page reloading. They also requested that the URL changes on reload and that you can visit each page by going to that specific url. Unfortunately, I don't know how to do this. I have found a lot of tutorials and snippets that are half way there but they don't offer the exact functionality.
For example, if you go here: http://lookseewatch.com/independentinsurance/commercial-insurance/
You'll see a long sidebar of different types of commercial insurance they offer. When you click on "Automobile," or any link for that matter, the page should be loaded into the div area on the right of the sidebar. The url then should change to reflect this change to http://lookseewatch.com/independentinsurance/commercial-insurance/automobile/. All of these pages are separate and dynamic in Wordpress.
Can anyone offer me some assistance? This is currently how the sidebar is being generated:
wp_list_pages('title_li=&child_of='.$post->ID.'');
Let me know if you need any other code from me or have any questions about the functionality.
Thank you!
This is kinda complicated. There are a lot of ways of catching user events, stopping default behavior and running custom code over it. For exemple, you can listen to anchor clicks and return 0 to not load their links.
But if you change URL in browser address bar, as long as I know, a JS can't control it, because it's outside of a webpage domain, and controling browser components from an external webpage would open a lot of security flaws.
This looks like they wanna avoid banners loading to count less hits :P If performance is the issue, first of all you can use a cache plugin, that will store in HD all DB queries, and use those files in future pageloads instead of making new queries.
You can also build a full sidebar into a PHP variable, cache it in HD and read from there, instead of building the whole code everytime. It will be like adding static HTML snippet.
This can be done with a technique called pushstate combined with AJAX. There's a great jQuery plugin that's called PJAX that implements this. http://pjax.heroku.com/
I have just published a plugin called WP-PJAX that makes to whole wordpress site PJAX driven. I'm not sure if this solves your problem, but it might be something for you.

I am looking at the Gawker blogs (http://io9.com, http://lifehacker.com/) and I'm curious about how they are made.
When I click for on a link only the article part of the page reloads displaying a loading icon while it does.
But what I can't figure out is that links point to new URLs like io9.com/something/something and its not something like I see on ajax pages that they put a site.com/#something tag at the end of the url from javascript to mark the page after an ajax request.
Can I change the full blown URL from javascript or what is happening?
When it happens, the website is using the HTML5 History API. This API can change the url (via JavaScript) without changing the page.
See caniuse.com for browser support.
If you would like to implement it in yout website, backbonejs.org would be very useful.
