Is AJAX to load embeds possible in AMP? - ajax

Quick question: Is it possible to dynamically load content like
<amp-twitter
data-tweetid="611193269532295168"
layout="responsive">
via AJAX into an AMP article?

AFAIK, it is not possible but AMP - LIVE-UPDATING AMPS
a new AMP component that updates page content dynamically without additional navigation or reload: readers looking at an earlier version of the page will simply see new updates as they come in.
The amp-live-list component adds support for publishing live updates to AMP pages as new content becomes available in the source document. This works great for implementing live blogs.
In other words, the AMP runtime will poll the server for updates to the origin document, fetching itself. The server can returns the entire AMP page or parts of it, and the runtime updates the page in-place seamlessly.
You can also check a related SO question can AJAX polling be used with AMP? that discusses how to dynamically load updates for the AMP pages.
Hope this helps.

GA solutions for AJAX sites

the new /solutions/ page is actually a single page with a series of called content via JS, which is to count as pages. These pages are noted by the query parameters triggered by using the filter (middle of the page).
GA is only noticing the /solutions/ page and not the corresponding pages b/c the way that AJAX renders and due to the universal tag living in the static portion of the page. We need to ideally find a route to track all unique pages called and any engagement in those sections.
You can use virtual pageview in Google Analytics to track single page application.
This guide describes how to use analytics.js (but you can do it through Google Tag Manager or Tealium too) to measure page activity on sites whose content is loaded dynamically without traditional full page loads:

jQuery mobile - after browser refresh page totally messed up

I'm developping a jqm application with spring mobile in the back-end.
Whenever I hit the browser refresh button on my mobile phone the page is completely devastated afterwards. Browsers back-button works properly.
The data are still available due prg pattern (flashAttributes in Spring) after refresh. Only the view is malformed.
Any ideas how to solve this problem?
From jQuery Mobile docs :
The simplest approach when building a jQuery Mobile site is to reference the same set of stylesheets and scripts in the head of every page. If you need to load in specific scripts or styles for a particular page, we recommend binding logic to the pageinit event (details below) to run necessary code when a specific page is created (which can be determined by its id attribute, or a number of other ways). Following this approach will ensure that the code executes if the page is loaded directly or is pulled in and shown via Ajax
So what happens is - in jQuery Mobile, the scripts and styles defined in the head are loaded only once. So, in normal conditions, it works fine, as all the pages will use the scripts loaded from the first page.
But. When you refresh a page in-between, it triggers a page-reload instead of the ajax navigation model thatjqm uses. So all the scripts and styles loaded from the first page will not be included from here on out.
What you need to do is "reference the same set of stylesheets and scripts in the head of every page", so that even if you hit refresh in the middle, the scripts and styles that had been loaded from the head of the first page are loaded again.
I recommend you read the docs from the above link fully to gain a better understanding.

Custom title and image for Facebook share button on AJAX result

This question exists in different flavors, but not for AJAX pages.
I use AJAX to pull a single video into my page and I want a custom FB share button for it. Everything I've read so far says that FB pulls the required title and image from meta-tags in the page's < head> section (og:image and og:title).
I've tried to change the meta properties when the AJAX call returns, before rendering the share button. This hasn't worked. It uses the values that were present upon initial page load. I have yet to encounter a single answer to this question.
Are there data attributes I can add to the 'fb-like' div to specify a custom title and image (similar to data-href)?
Danke!
You need an individual URL for each individual piece of content that you want to share. Open Graph objects (and simple shared links “become” such, automatically) are identified by their URL (og:url).
Now if your whole page is built on AJAX, you still need to create such individual URLs somehow – the Facebook scraper tool does not “speak” JavaScript, and relies solely on the OG meta information that the server delivers for any URL it requests.
Since the hash part of an URL is only of relevance client-side (and does not even get send to the server), “typical” AJAX URLs that rely on those to tell the client which piece of content to load in the background are no good here.
So if you want to share two pieces of content (videos) as http://www.example.com/?v=vid1 and http://www.example.com/?v=vid2, then you have to make sure that your server delivers the meta data for each video under its respective URL.

Load Wordpress page in a div without reloading page and while changing url

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.

How to load content from third party site, and from where?

I am developing a jobsite. I like to load career advice from anywhere (like blog, other sites, rss, etc.), and it should be updated automatically if there is a change in source.
How can I achieve this, and from where I can get the required content?
Perform an Ajax request on a time interval, if there are changes, then update the content on the page
