jQuery Tutorial for Beginners

About this course

welcome to this introductory video on jQuery in this video we’re going to talk about what jQuery is why we use it and we’ll talk about some basic syntax and then in the next video we’ll talk about

downloading jQuery and create some of our very first jQuery code now the first thing you will need to know for this series is beginning JavaScript because jQuery is JavaScript if you look in the

jQuery library it’s all JavaScript behind the scenes so you will need to know beginning JavaScript if you do not know beginning JavaScript I suggest you go to my main channel page and there is

a tutorial on beginning JavaScript so again jQuery is JavaScript but it’s actually a framework or library of JavaScript common JavaScript code that you can reuse and reuse again and the

good news is it’s all free that’s right jQuery is an open source library that also means anybody can contribute to jQuery so that’s actually good because if someone creates a really cool feature

they can go ahead and add it to the library so that you can use it the other point I want to make about jQuery is it’s easy to use you use less lines of jQuery than you do ordinary JavaScript

so again everything that you do in JavaScript you can do in jQuery jQuery is also feature-rich you can build websites using jQuery so there is a lot of functionality that you can use and

there’s also a lot of cool effects that you can do you can do animation you can do sliding fading hiding and all sorts of complex event handling and we’ll go through all of that in this series

another nice item about jQuery is cross browser compatibility you do not have to worry about which browser version you’re coding for one line of jQuery will be compatible on all the different types of

browsers now jQuery uses CSS selector methodology and isn’t that great CSS in my opinion is one of the best designed languages and so they basically took one of the best parts of CSS and implemented

that into jQuery so selecting Dom elements is much easier in jQuery and that also means if you already know CSS it will be very easy for you to start picking up

because it uses that CSS selector methodology so if you take a look at this basics index right here this is some of the most basic syntax you can get for jQuery it always starts with a

dollar sign and that actually represents the jQuery library and then we have open parentheses and then you just put the selector in quotes and that’s it that’s all it takes to select a Dom element so

jQuery is really really easy for selecting Dom elements and you can see here we can use a class selector we can use an ID selector a type selector a descendant selector and many other

different types of selectors so that’s one of the reasons that jQuery is so popular it’s a lot easier to select elements we don’t have to use the get element by ID

you took my JavaScript series you’ll remember that one very well that’s done for us in the background when we use the ID selector so that’s really a nice nice thing about jQuery okay so in the next

video we’re going to get started with our first jQuery code and I will also show you where to download the jQuery library see you guys in the next video
