Best Features that JQuery Offer – Coder’s Eye

Featured image of Features of JQuery

Beyond what are simply benefits of learning the JQuery language, there are a host of features that make the language JQuery both desirable to learn and useful. CSS selectors, or the ability to use JQuery with Cascading Style Sheets is useful. There are also a lot of user functions available to the user, and the user interface itself is notable. These features and more add up to a rich feature set that allow a JQuery coder to have a good experience while coding on any task.

JQuery CSS SelectorsJQuery Mobile Selectors

If you are a front-end developer, odds are you are working with Cascading Style Sheets, or CSS. CSS control the look and feel of HTML documents, and were a precursor to JavaScript. In CSS, selectors are functions that can be used to change the look and feel of a particular object on the page.
 The new version of CSS, CSS3 is being implemented heavily, and JQuery has direct support in production code for CSS selectors, making it easy to change the page layout and feel from within your JQuery code. While JQuery itself can work with design elements, in CSS implementations this can be a very useful tool to the Web developer.

 

Functions

As with any programming language, JQuery uses functions. However, unlike standard object oriented programming, it derives them from libraries rather than user-written code for the most part. JQuery has an extensive base of library functions available, making the code easy to implement for repetitive tasks and things that would be difficult to code by hand. Something like a dialog box or popup that could take many lines of JavaScript code can be condensed into a few lines or even one of JQuery code by using predefined functions that create the required element.

 

Easy User InterfaceMobile Jquery Interfacing

JQuery has an extensive community-supported user base and is a robust language. Therefore, many functions, programs, and interfaces have been created. Some of these are designed to enhance the user experience itself. These extras have been bundled into the core of the language, in a package called JQuery User Interface.

    True to its name, JQuery UI allows you to create stylistic user interface design with a minimum of coding thanks to the support of developers. The previously mentioned dialogs and popups, accordions, sliders, date selection tools, and navigational menus are all available as library elements. Inserting them, instead of requiring lines and lines of code, requires only calls to the library function. For instance, instead of writing a complete menu structure in JavaScript, you would call the navigational menu function and add elements and destination pages. The entire UI development process is designed around simplicity in JQuery.

JQuery PluginsAll Jquery plugins that they offer

JQuery has stuck to its core from the beginning in standard, but has allowed the User Interface package as well as third party objects known as plugins. These plugins can be anything that can be created in JQuery. Once these JQuery plugins have been created, they can be used across the entire project without having to re-code the plugin in each use. What’s more, you can make the plugin available to the development community.

    On the inverse side, plugins that are available from the development community are extremely diverse. Almost every element that can be made or UI widget that has been used has become a plugin. These plugins can be used as easily as standard JQuery code and allow you to save time in programming your projects.

    A major benefit to using plugins is bandwidth. Rather than using repeated code instances, using a plugin across your site allows the download and local caching to take place once and then the code need not be sent again unlike hand-coded elements.

    JQuery as a language is focused on being lightweight and avoiding large, extensive code, so plugins are a natural extension of that philosophy.

    As we wrap up the major features of JQuery, it is easy to see why JQuery is becoming an increasingly popular language. By allowing compatibility with a senior technology such as CSS, you allow extensibility to the language. Utilities allow you to add to your own coding experience without much effort. And libraries and plugins allow you to write a lot with a little – the philosophy of JQuery. Earlier Web technologies such as HTML require you to explicitly code your website for each page, while JQuery tries to avoid code repetition by offering libraries for as many ideas as have been published.

    In our next piece, we will be talking about JavaScript libraries, what they are, and how they affect JQuery coding. In fact, they are the backbone of coding. Hopefully by now you are getting a good grasp of what JQuery is and can do for you as a Web developer. Follow the rest of the series and see how to turn these philosophies into finished code and move on towards success as a JQuery coder.
