AJAX Dashboard

Ajax stands for Asynchronous JavaScript and Extensible Markup Language (XML). These are techniques that are used to create websites that allow processing of objects even though their transmission may not be fully done on the client side. Due to their asynchronous nature, Ajax programming is common in interactive websites. The combination of XML, HTML, and JavaScript has made it possible to script websites that can be considered as intelligent in both the machine and user access.

The popularity of Ajax as a programming tool has been aided by the various advantages associated with it. Firstly, it makes interaction between developers and their websites easier. When using these programming techniques, one does not need to reload the webpage to display content that has been recently added. Instead, the webpage reloads itself automatically, displaying whatever new content that it comes across. This is one of the features that has made it a must-have tool for webmasters and website developers.

The ease with which users can navigate websites that are created in Ajax is also one of the greatest advantages associated with the tools. Web pages created in Ajax are straightforward, and XML makes them easy to read and maneuver within. The flexibility of the websites has made it effortless for users to access content and has it load on the browser at the click of a button.

Thirdly, the ability of Ajax as a programming structure to support a variety of web browsers is one of its greatest assets. This programming language has support for all types of browsers available in the market today. Apart from this, the platform on which the browser is used is not also limited to any particular ones. Content that may require Flash support from the browser can easily be loaded the same way desktop applications load, and thus allow the user to access them.

Additionally, these techniques are used by web developers because of their compact nature. Websites created in standard programming tools may have thousands of lines of code. On the other hand, Ajax is compact in that a few lines of code are able to generate a greater output. Multipurpose applications can be made to run on a single web page using Ajax, but they would require individual web pages for other languages. This compactness translates to low bandwidth requirements. This is good news to the user since it enables him to load web pages even with the smallest of bandwidth available.

Lastly, websites that require some form of data entry are best coded using Ajax. This is because it allows validation of forms on the server end even before all the data is fully entered. Once validation is done, data entry becomes as easy as feeding data into a text processor. Drop-down menus and radio buttons can also be easily edited using Ajax. Anytime a form is changed, Ajax calls make it possible for the changes to be effected on the client side browser interface without having to reload the page. Ajax calls are constantly running the script to detect any changes in the code and communicate the changes to the browser.

Most people who have traversed the web have also heard the term “HTML”, and many have a basic understanding of it. But for those who understand and use HTML, regardless of whether for personal or commercial purposes, it is a powerful tool.

HTML is actually an acronym for “hypertext markup language” and it is universally recognized by the software that is used to surf the net – the web browsers. In order for web browsing software, such as Google Chrome, Mozilla Firefox, and Microsoft Explorer, to display web pages correctly, the pages must be written in a code that is mutually understood by the originator of the information as well as the receiver. This is accomplished by use of HTML, which is used by the originator to determine how the information will be displayed on the web. Once the information has been uploaded to the web in HTML format, persons who are looking for this information are able to view it through their browser software of choice, in the format and with the visual results chosen by the originator.

How Does HTML Work?

HTML communicates with web browsers by the use of “tags”. These tags signal the browser that the information should be displayed in a certain way. HTML tags can be compared to road signs. They direct the browser to show the material in a certain way until the next tag is encountered which will direct the browser to display the subsequent information differently.

These tags work by using the “less than” and “greater than” (< and >) symbols as signals to the browser that either a new direction is forthcoming or a change in direction. The < symbol basically says “do something new here”, followed by an HTML-applicable word or phrase and subsequent instructions that follow the protocol for HTML. When the particular set of instructions is complete, the forward slash symbol (/) signals the end of the instructions, followed by the appropriate closing tag and a >.

For instance, every web page should have a header that includes the title of the document or page. At the point where the web designer wishes the header to appear, the following tag is typed: . This is followed by the instructions for the information that is to be included in the header, which may require additional tags, such as that of a title. So, a simple header that is to include the title, “Sailing Is Fun” might appear as follows in HTML:

Sailing is Fun

Notice the use of < and >, as well as / in the above example. An HTML standard word or phrase (also referred to as a “tag”), enclosed in “< ” and “>”, serves as an opening signal that tells the browser that what follows is to be displayed in a certain manner. At the end of the particular information, the ending tag tells the browser that the data is no longer to be displayed according to the opening tag. An ending tag is the same format as the beginning tag, except it uses the forward slash symbol (/) to tell the browser that the opening tag is now to be closed.

Resources for HTML Tags

There are many applications on the market today that will translate the user’s data into HTML code, which make it much faster and easier to prepare and upload web pages without the necessity of learning complex HTML codes. However, it is always useful for web designers and developers to have a basic understanding of HTML for purposes of refining and changing appearances of data within these applications.

Libraries, bookstores, and web sites are rich resources for HTML tags, codes, and instructions in their use. With just a bit of practice, it will soon be easy to see how even a basic knowledge of HTML can help to make a good web site that of a great one.

Ever wondered why some web pages seem not to load at all but still process your requests? Web programming has moved from the era of static websites to the now dynamic age. In the days of just html, whole pages had to reload every time you click a link or fill a text field. Now, AJAX has made it possible for different parts of web pages to carry out specified requests without affecting the rest of the page. AJAX, an acronym for Asynchronous JavaScript and XML is a method of sending data between the client (you) and the server without transferring the whole page.

It updates different parts of a webpage, leaving the whole page intact. This creates a better experience for you being that dynamic content is processed in the background. Some examples of applications that use ajax .net include: Gmail, YouTube, tabs on Facebook as well as Google Maps. For example, when you click the “share” button on Facebook, the whole page does not load. Instead, the button just gets inactive and then your status gets updated. That is AJAX at work. Also, the suggested words that appear when you type in the Google search box are a function of ajax .net. As you type, the letters are sent by the JavaScript to the server, which gives you suggested words.

AJAX works in conjunction with four other functions to give you that dynamic web experience.

1. JavaScript or DOM (Document Object Model): This is responsible for displaying and interacting with the information you input.
2. XML Http Request Object: This creates an asynchronous transfer of data with the server.
3. CSS: The Cascade Style Sheet is responsible for giving your webpage its good looks.
4. XML: This is a format of structured data that can be accessed by various programming languages. Although, ajax .net is not a newly developed language, it’s simply a better way to implement other standards in existence.
