HTML 5 is the latest version of one of the first languages for websites. The project was started in 2004 – a fitting timeline considering the improvements in the software and online industry have been very impressive. This update in HTML plans to cater more than just simple interfaces in properly building a website. On the earlier versions, HTML is just made to load the entire webpage for every data request. Although this setting is still adaptable to simple websites, the increasing load for browsers even with HTML has prompted call for significant changes in website languages. The mere fact that the addition of other programming languages in most websites should make

Figuring out DOM for JavaScript is a little bit tricky because of browser incompatibilities. Although you should be able to load an Ajax based application in most browsers, the reaction of different browsers to JavaScript is different. Developers have to create modifications in their application most of the time if they wanted to ensure that their application is readable in all browsers. Without modifications, the application will not be able to adapt to different browsers and may even open up to different security questions. One of the reasons of browser incompatibility is in the variations of document types in DOM. There are developers who prefer to launch a specific

One of the biggest challenges for JavaScript and Ajax based developers is on using DOM for various browsers. This is not only based on browser incompatibility but also on the ability of the application to load faster in the client side. If the application will not load as expected, users might stay away from the application which lowers the feasibility or usefulness of the application. Loading problem for developers often stem from the fact that the entire webpage has to load first before JavaScript function is executed. Developers execute window.onload=function () so that the function will check if the webpage is fully loaded first. Although this function is very feasible

Ajax would be nothing without XML. After all, the “x” in the acronym stands for XML which means it is a very important aspect in the Ajax based application. There are those that are not even Ajax that uses XML. For example, JavaScript could still use XML as its data format especially when developers needed to improve their application in terms of availability to other websites. Since it’s considered as the universal data format, developers have been using XML to ensure that their application will work as planned. But even with the known ease in using XML, there are still challenges developers have to go through in building an application through XML. Chal

jQuery has practically become one of the most powerful JavaScript libraries. Even before JQuery has been adopted by Microsoft as its main library for JavaScript, it has already been adopted by developers worldwide. It’s simplified library, variety of options for developers and massive support from users worldwide has pushed jQuery to leaps and bounds that only a few JavaScript library could match. Just recently, the said library updated their user interface (UI) which is a massive upgrade. New tools and notable features have been added to the new version which will upgrade the performance of an Ajax based application. Working with Version 1.3

Proper data handling in Ajax is always the primary purpose of developers in looking for ways to effectively develop the application. The different data formats are usually judged not only how they could be seamlessly implemented from the source but also on how the data format would be successful in returning data. Considering browser incompatibilities, security and ease of manipulation, developers are usually choosing a different data type to effectively implement their application. For Ajax, the most popular data format is XML – a lightweight data format that could easily move within browsers, most developers have come to prefer this specific data format because it can be u

External sources for JavaScript and an Ajax based application used to be ill advised to developers for security purposes. However, because of the advancement of JavaScript techniques and more security measures implemented in coding, invoking a source outside the client side is already tolerable. Invoking external functions could be possible as long as they come with .js file or the specified data format of the application such as CSS or JSON. But if the developer wants to push further for more data and interaction, they could even invoke PHP as part of their application. This might seem impossible at first but because of the increased functionality of JavaScript, developers can no

Regular expressions are all about matching the user’s input to the application requirements. Although the system could accept any data without regular expressions, it will not push through since it will never be authenticated. With smart usage of regular expressions, developers should be able build a highly interactive application that screens the data. One of the key functions of regular expressions is pattern matching. As the name indicates, it’s a system within the application that determines if the input is according to the set pattern. When the pattern matching capabilities of a regular expression is set, then the data could flow through the function. Patt

Regular expression or RegEx may look like a simple function in an Ajax or JavaScript based application but it’s presence in these forms of applications is very importance since they help in screening the forms of data coming into the application. The common forms of Regular Expression will screen if the data is created according to the specifications of the developers. But there are other additional functions in RegEx that proactively work with the data provided by users or actively change the data found in the application. Through these functions, developers would be able to build or customize regular expressions according to the specifications of developers. The fo

One of the biggest challenges in an Ajax or JavaScript based application is in determining whether the said function would properly work in the user’s browser. Even though Ajax and JavaScript have developed into something powerful that it could deal with simple challenges posed years ago, there are certain abilities in an Ajax based application that can’t just be solved. The browser specific function is still a great challenge for developers. Each function in a JavaScript based application can’t just be easily loaded in each browser since each browser has different interpretation on how the application will be used. Without customization per browser, developers w

Dealing with JavaScript or an Ajax based application is always a tricky task. Even the most experienced developers would end up with unexpected errors especially when the application is tested for the first time. Bugs and error in coding will always be there and the possibility of errors showing up after the application has been launched is still there. For that reason, some developers are opting to provide some error prompt within the application. The error prompt could be easily customized in JavaScript and the message could be as simple as “Page Error Encountered” to outrageous messages such as “Nope, the Function is Not Here.” But whatever the message w

Notation is one of the most rarely used commands in JavaScript. This type of command is added on nodes as provider of additional information for the browser. But notation is not just added in any node – notation is added on unparsed nodes. Any data that might not have enough information about its features or when the data is not properly categorized for proper functioning could be effectively defined with the help of notation. The function is usually added in the top of the node so that the browser would have an immediate idea how the application would work. The reason why the command notation is not extensively used in most applications is on its availability to oth

Properly implementing Document forms in JavaScript could be the trickiest part in building an Ajax or JavaScript based application. The command Document enables a speedy implementation of any webpage in the client side. It is actually a command that could be implemented in the background specifying the coding language which is the coding for the client side. Basically, Document command in JavaScript is used to inform the browsers the type of programming language that will be used. This will aid the browser in properly implementing or preparing the browser so that the Ajax based application will be properly implemented. Customization on JavaScript

There are Ajax based applications that will require cookies from their user. By enabling cookies on the user side, the application can easily interact with the user since personalized information could be extracted. This will significantly increase interactivity since cookies will practically inform the application regarding the user’s preferences. Enabling cookies in the application will also help the developers protect their application since they will know who will access their application and what actions have been done on the application. Cookies could be controversial in terms of user security, but it enables personalization of interaction as well as application protec

Sometimes, the small functions in an Ajax based application are the ones that are most important. But even in a massive application, the small things should never be ignored. They might be considered as a leak where the point of attack will commence. Without securing the small things, your application might be destroyed without even knowing it. In this article, we take a look at three popular functions not only in JavaScript and Ajax but also in other programming languages: prompt, alert and confirm. These three functions will increase the interaction of the application. These functions are lightweight which requires little resources from the developer and the user.

Depressible image is a form of interaction in Ajax and JavaScript based application that deals with photos and links. It is a very simple looking interaction wherein the image would pop-up or become smaller whenever the mouse is pointed to the image depending on the preferences of the developer. Although this looks very simple, the interactivity provided by this function is very impressive. Through depressible image, you’ll be able to increase interaction in your application or even in a simple website. What is even better is that launching this particular function is very easy. There are simple prerequisites that you have to remember and functions you need to use to

XML is one of the core factors of an Ajax based application. Although there are other data formats that could be considered with JavaScript such as HTML and JSON, none of them provides the universality and lightweight features found in XML. This form of data could interact with any browser in any version and it will not have any heavy footprint which ensures the accessibility of the application. This is very important especially in building efficient client side application. Through proper use of XML, it can improve the website significantly without requiring too many resources. There are many retrieval techniques allowed within Ajax. But the most popular and probably the

XML is a must for most Ajax based applications. It’s a universal mark-up language which means almost any programming languages could work with XML. Aside from being accessible through various formats, it is also known to be relatively lightweight. It can be used in small online applications for faster processing or could be implemented in robust applications for a more complicated data manipulation. By properly calling XML in the application, developers are assured of a well functioning application. In an asynchronous setting, this is a bit challenging because of difference scenarios developers have to deal with. The Undying Browser Incompatibi

An Ajax based application could work with XML, JavaScript, CSS and a little bit of HTML. Other programming languages could be part of this client side programming technique but they are often regarded as an add-on and not a part of Ajax. The combination of these programming languages has made Ajax into one of the most powerful programming techniques. Instead of simple websites, highly interactive Ajax based online applications are created. It can even be said that the reality of cloud computing has been made possible because of the advancement of Ajax based applications. But when it comes to programming, Ajax is one of the most difficult to code and maintain. The variables

Creating an Ajax based application with XML ensures functionality and ease of development from developers. Because of XML’s ability to work with different browsers and programming languages, XML enable developers to build applications not just based on JavaScript for Ajax but other programming languages that combine the best functionalities. XML ensures mash-ups of different frameworks for JavaScript and Ajax. This means the possibilities in the application is almost endless. The improvement of XML on Ajax cannot be possible with the help of DHTML. This lightweight yet highly dynamic version of HTML provides the interaction while maintaining one of the best features of HTML
