5 Ways to Make Ajax Calls with jQuery. There are at least five ways to make AJAX calls with the jQuery library. For beginners, however, the differences between each can be a bit confusing. In this tutorial, we'll line them up and make a comparison. Additionally. we'll review how to inspect these AJAX calls with Firebug as well. This section is for those who have no idea what AJAX is.

Click on the first button named "load(). " Below is the JavaScript code for this effect: $.ajaxSetup forces the browser NOT to cache AJAX calls.After the button is clicked, it takes a little while before the new HTML is loaded.
Now, let's explore more details of the request with Firebug: 609 + Ajax/Javascript/Dhtml examples and demos to download. Alex MacCaw - Asynchronous UIs - the future of web user interfaces. It's an interesting time to be working on the frontend now. We have new technologies such as HTML5, CSS3, Canvas and WebGL; all of which greatly increase the possibilities for web application development.
The world is our oyster! However, there's also another trend I've noticed. Web developers are still stuck in the request/response mindset. I call it the 'click and wait' approach - where every UI interaction results in a delay before another interaction can be performed. Speed matters; a lot. Amazon: 100 ms of extra load time caused a 1% drop in sales (source: Greg Linden, Amazon).Google: 500 ms of extra load time caused 20% fewer searches (source: Marrissa Mayer, Google).Yahoo!
Yet, despite all this evidence, developers still insist on using the request/response model. A good example of the problem is Gmail's 'sending' notification; how is this useful to people? As developers, we should optimize for the most likely scenario. The solution The result Not a silver bullet The implementation. 1030 + Ajax/Javascript/Dhtml examples and demos to download.

Asynchronous Technologies: AJAX, AJAH, AHAH, and AJAJ. Hey guys and gurls! Today we are going to take a look at different asynchronous technologies. There are many variations of them over the net. They’re AJAX, AJAH, AHAH, and AJAJ. AJAX (Asynchronous Javascript and XML) – is a technology for asynchronous data transmission between the browser and the server. Introduction Before we get started, i’ll tell you a little bit more about data transfer solutions… The title AJAX referred to XML, although at present, for asynchronous data transmission, it is used less frequently (in pure form, at least).
I will lead examples using jQuery JS framework. jQuery supports all three types of asynchronous data transfer. There is a lot of features to work with AJAX in jQuery, but the main ones being. get () and. gost () . $.post(url[, params[, callback]]) $.get(url[, params[, callback]]) Examples index.html version.php echo phpversion(); Also in the directory with these files we should have jQuery library: jquery.js.

The Google Hosted Libraries is a stable, reliable, high-speed, globally available content distribution network for the most popular, open-source JavaScript libraries. Google works directly with the key stakeholders for each library effort and accepts the latest versions as they are released. Libraries To load a hosted library, copy and paste the HTML snippet for that library (shown below) in your web page. For instance, to load jQuery, embed the <script src=" snippet in your web page.
We recommend that you load libraries from the CDN via HTTPS, even if your own website only uses HTTP.

Making users click through multiple pages just to edit a field is so 1999. In this tutorial, you'll learn how to create an in-place editing system as found on popular sites, such as Flickr. A word from the Author With all the buzz around Web 2.0, ease of use is now much more important than ever. Being able to edit some content without having to go to another page is something a lot of users really crave. A lot of big names are already using this pattern to great effect. If you've used Flickr, you've probably seen this in action. I believe a demo is worth a thousand words. Today, we are going to look at how to implement this with, you guessed it right, our favorite JavaScript library, jQuery. Design Goals Before we start looking at how to implement the functionality, here are a few thoughts about the goals and the resulting decisions.
We need to let the user edit the content without leaving the page. Now that we've mapped out our needs we can now move on to how we are going to do this. Gwt-eclipsecon-chat - Project Hosting on Google Code. This project is an interesting example of an application built using the Google Web Toolkit (GWT). Kelly and Miguel spent a Sunday afternoon prior to their tutorial at EclipseCon 2007 developing an instant messenger web application. The source for Chattr is available in the Downloads section, and you can either get the 'complete' app version, or a version that is 'working.' The latter was intended for those people who were following along at the tutorial.
More about GWT, in case you're unfamiliar: GWT is an open source Java development framework that lets you escape the matrix of technologies that make writing AJAX applications so difficult and error prone. To get started, download GWT. 10 Edit In-Place Ajax Scripts. In an Era of Ajax and an increase use of Edit in place, I decided to put together a list of edit in place scripts. I hope this list will help you in your quest to make your web application or website more user friendly.

In a nutshell, it is the use of the nonstandard XMLHttpRequest() object to communicate with server-side scripts. The DOM plays into Ajax in a number of ways. This probably sounds very confusing, but it is pretty easy once we go over a few simple examples.
As with the DOM Scripting examples (above), for a blow-by-blow of what the script is doing, read the JavaScript comments. Example 1: Ajax with innerHTML#section1 For a simple innerHTML-based Ajax example, we’ll create a quasi-functional address book application. <!
