Free JQuery Tutorial

Welcome to free tutorial series on Jquery! When you finish our free training you should be ready to move on to more advanced training in the use of JQuery through other channels. We will discuss the language, its usage, the benefits of using JQuery and industry users of JQuery. In addition, we will provide you with an introductory tutorial to the syntax and usage of the JQuery language to provide you with knowledge you can use to be successful whether you pursue traditional or online training in JQuery.

Perhaps you have been told it’s a good idea to learn or try JQuery. Maybe you’ve seen jobs posted that list it as a requirement. Or, you’re planning on becoming a front-end developer. All of these are good reasons to learn JQuery. As you may know, JQuery is a language that is designed to help developers write JavaScript that is a simpler jumping off point than learning JavaScript as its own language.

JQuery is a way to use JavaScript in an easier fashion. It is what we refer to as a framework—you’re not writing JavaScript directly, you are using a tool that makes JavaScript easier to implement. JavaScript is a complete scripting language; however, JQuery is an application programming interface or API.  There is a difference between writing straight JavaScript by hand and JQuery. You can think of JQuery as a library that provides resources to help with JavaScript coding. The JQuery code interfaces with JavaScript and allows you to write entirely different and easier syntax to do the same thing.

While JQuery is its own language, it is a JavaScript library so knowing how to use JavaScript will make learning and implementing JQuery much easier. JavaScript is not a mandatory prerequisite for JQuery; however, much of the library content available is JavaScript code so the deeper you get into the language the more important a working knowledge of JavaScript will become. For day to day usage, JQuery can be learned as its own separate language without knowing all the nuts and bolts of the JavaScript language.

JQuery used as a WrapperExplaination of a Jquery Wrapper

We can look at the framework of JQuery as a wrapper, or a way to implement multiple commands in JavaScript with just one line of JQuery code. These multiple lines are wrapped in a function that is inside a JQuery library. For instance, a JQuery command may replace several lines of code in JavaScript by providing a function that does the same thing. Instead of writing several lines of code to create a dialog box that warns the user of something, you can simply use the library function to make a dialog box and tell it what text belongs. Therefore, it is easier to learn and more compact than writing plain JavaScript.

JQuery is a very popular language because it is easy to use, easy to read, is extremely robust, and allows you to write powerful code in less time. It is also easier to learn than plain JavaScript. In addition, plugins to JQuery make it more powerful and able to do even more tasks with less coding than before. The level of support for it means that plugins and extensions continue to become available, making coding easier and easier for difficult or repetitive tasks.

What is JQuery for?

Identifying all elements that go into what make up JQuery

JQuery is a front-end language, or browser-side. That means that the script that you write is sent along with the HTML documents that are part of the website as they are accessed. The browser in turn reads the script and creates dynamic content based on the script that you have written. When someone visits your site, the script is executed. This allows content such as forms, pop-up and pop-out windows, dialog boxes, alerts, and much more to be delivered as content to the user.

In summary, JQuery is a set of libraries that create an API framework that allows you to write JavaScript without having to hand-code every line. Community-supported libraries allow greater and greater functionality as the language grows. User interaction is on the browser side, embedded inside the HTML code, and executed on the visitor’s computer. This allows you to customize the user experience by adding dynamic content to the page. Doing so requires only the use of JQuery commands which have a neater, easier syntax than JavaScript. Next, we will discuss the benefits of learning JQuery.
