The Feel Of The Web

Maybe you use LinkedIn - http://www.linkedin.com or Jobster - http://www.jobster.com and very probably you have had a look at Google maps - http://maps.google.com/

If so you cannot but have realized that these sites and others have another look and feel. Its maybe not about but about the way in which they look faster and easier to use.

Perhaps you have noticed how the feel of the web is changing?

Maybe you use LinkedIn - http://www.linkedin.com or Jobster - http://www.jobster.com and very probably you have had a review of maps - http://maps.google.com/

If that's the case you can't but have pointed out that these sites and others have a different look and feel. Its perhaps not about but about the way they appear easier and faster to use.

Numerous internet sites are slow and tedious giving you the impression thatyou have the required time to get a coffee or even go to lunch. It is the horrible hourglass. You click a link and the hour-glass appears because the site contacts the server and the server ponders what it's going to send back to you.

There's a reason behind the new sites being nicer to use and faster. Their called AJAX.

Perhaps not the solution created in 1947 nor the mythical Greek hero but a web development strategy.

AJAX is not new technology but a combination of existing mature technologies. Their an abbreviation for Asynchronous JavaScript and XML and a web development strategy to make web pages feel more responsive. It does this by exchanging small amounts ofdata with all the host behind the scenes and shows it without re-fetching the entire page in the same time, hence the word Asynchronous.

In case you are not completely clear what asynchronous means, synchronous means that processes are based mostly on other processes 1 >> 2 >> 3 etc whereas asynchronous could be the capability to manage processes separately from other processes.

It might seem that adding a level to any ap-plication can make it less reactive, but because the browser first loads an AJAX motor responsible for both providing the software the user sees and talking with the machine on the consumers benefit the user is extremely seldom looking at an hourglass icon waiting around for the serverto take action.

Every individual activity that normally would produce work with the server goes to the AJAX motor instead. Any response to an user activity that doesnt need a trip straight back to the machine the engine handles by itself. It makes these requests asynchronously without affecting an users interaction with the application if the engine needs something from the host to be able to respond.

All of this means AJAX is pretty just now - somewhat like Flash is. It may be very attractive to use AJAX mainly because AJAX is cool or my boss told me to.

But when you're creating any site you should think of your visitors first. What do they want this application to complete? What will make it easier-to use? A good guideline as to whether or not to utilize AJAX IS: AJAX is for action not material.

You should think again if you're not accessing data that changes then. The point-of the asynchronous request is that it makes demands to-the server for data that has improved faster - while the reader is performing something else because it's happening. Should people desire to learn supplementary info on https://www.facebook.com/, we know of millions of on-line databases people might think about pursuing. Then when they click a link or switch data shows up right away. Then you probably shouldn't use it to be accessed by Ajax, if your content or data never or seldom changes.

Then there are other issues:

Page changes

There is a brief moment of re-adjustment when the material changes when an entirely new page is produced. Since this doesnt happen with smaller portions of the display this becomes more apparent. This can leave people wondering.

Seo

Research machines don't generally read the JavaScript code necessary for AJAX. This can mean AJAX pages remain un-indexed unless a static page is provided. This lofty www.facebook.com/eric.schames paper has diverse great cautions for the inner workings of it.

JavaScript

As AJAX utilizes JavaScript, which can be applied differently by different browsers as well as different versions of the same browser the JavaScript may need to be rewritten for several browser( s) type( s) though history libraries are solving this, but a problem still appears if the user has switched off JavaScript help in the browser.

Net analytics

Many web statistics answers are based on a new page being loaded when new or updated content is shown to the consumer or to monitor an approach such as a check-out. Since Ajax shifts this care must be take-n to take into account how to ensure a page or even a percentage of a page might be properly tracked.

Having published anything above, Google has made a massive investment in developing AJAX web sites. All of the main services and products Google has presented including Orkut, Gmail, Google Groups, Google Suggest and Google Maps are AJAX applications.

However AJAX [and other terms such as Rich Internet Applications or RIA for tolls such as Flash] are merely new terms for a technologies and technology combinations which have been around for years.

Given the hype for these conditions, it is reasonable not-to get carried away. Careful assessment of when and how to use AJAX is vital.

Dont neglect that other applications and Flash still don't form the foundation of most web sites and people need simplicity first. If AJAX improves the users experience whether via design or speed then its worth considering watchfully..
