It is one of the most popular JavaScript libraries. And this is not surprising for those who use it. It allows you to simplify, speed up and, most surprisingly, improve the development of JavaScript scripts.
Advantages :
- Very convenient work with elements based on CSS selectors.
- Excellent cross-browser compatibility. Many programmers do not think about cross-browser compatibility, however, it is necessary, because different browsers can process the same code differently. takes into account all these nuances, and you no longer need to think about it.
- Excellent animation capabilities. Animation decorates the page and makes it more enjoyable to use. It is simply impossible to make animation easier than what is implemented in .
- A large number of ready-made plugins. It may take several days to make the same image slider in JavaScript. And you can install and configure a ready-made plugin in a few minutes.
Based on this, everyone who develops scripts in JavaScript should know. And the purpose of this category is to teach you how to use, and also to show examples of use, for example, from my own practice.

Humane.js
A good Jquery script that allows you to display alerts on the page in the form of pop-ups. It supports mobile devices, is lightweight, well documented, and most importantly, notifies you unobtrusively, without interfering with your viewing experience.
Impress.js
The script allows you to create excellent presentations on the site. Extensive customization options, support for keyboard control. I recommend watching the demo to make it clearer what we are talking about.
PDF.js
A very interesting script. Allows you to generate a PDF document from page content using HTML5. Now, to download an article in PDF, you no longer need to use third-party services; everything can be done, as they say, “without leaving the checkout”
jQuery Transit
A very sophisticated JQuery script that can do almost everything with objects. Squeezes, moves, stretches, twists in any way - a lot of options for use. It uses the CSS3 transformation mechanism and weighs very little - only 2 kilobytes in compressed form.
ResponsiveSlides.js
Good news for those optimizing their site for mobile using @media. This small-sized slider works with all browsers, starting with IE6, mobile devices on all modern OSes and allows you to scale images to fit the device’s screen resolution. A must-have for all mobile developers
Response.js
Script tool for creating mobile-friendly websites. Supports HTML5, has a bunch of settings for a comfortable developer's work.
Slabtext
An unusual script that allows you to create large headlines that are now fashionable. The principle of operation is as follows: the script takes a line, counts the characters, divides it by the length of the line, and cleverly calculates how many characters are needed on each line, taking into account the division into words. Then he adds a little magic and... it’s better to watch the demo, because I don’t have enough words to explain how it works
Scrollrama.js
An interesting script that allows you to implement various scrolling effects on the page. By the way, these scroll effects are gaining popularity, I notice them on many sites.
Textualizer.js
Allows you to apply various animations to literally every letter on the page. Highly customizable, good cross-browser compatibility, lightweight and nice enough plugin to add a little “creative” clutter to your page
Sticky
A good script that allows you to make any element on the page always visible, for example, when scrolling down, the top menu will always remain in place. You can do the same with a sidebar or any other element.
For those who doubt whether or not to use JQuery scripts or whether they slow down loading too much - don’t worry. The main thing is not to overdo it with beauty and functionality, and then everything will definitely be great!
10 years ago, when jQuery was just in its infancy, the browser ecosystem was very diverse and each of the products that existed then struggled with the complexity of manipulating DOM elements in its own way. The ambitious goal that the jQuery developers set for themselves was to develop a universal approach to solving these problems and create an API that would work equally well in any situation.
As far as they were able to judge, but after 10 years of its existence, jQuery remains one of the most popular JavaScript libraries.
JavaScript itself is now a completely mature product, well documented and supported by all modern browsers. The modern browser community is also more consolidated and, in most cases, you can be sure that if, say, a page is displayed correctly in Crome, then it will look the same in Firefox. querySelectors are also supported by almost all modern browsers.
It would seem that the history of jQuery development is moving towards sunset - why overload pages and waste extra processor cycles if most problems can be solved using standard language tools? On the other hand, over such a long period for the computer industry, a huge number of solutions have been developed that can simply be taken and used, here and now.
I think this choice should be made by the developer himself in each specific situation, focusing not on fashion and trends, but on common sense and the prospects for the development of his creation.
In this review, I have collected all the free jQuery plugins that I know of that are currently actively being developed or that have been updated at least once over the past year. Some of them I actively used and use in my practice, some I know only superficially, but they impressed me with their capabilities. Among them there are exceptionally extraordinary ones, made with great imagination. And even if you don't find a way to use them in your projects, maybe they will inspire you to create your own, even more incredible solutions.
multiscroll.js An interesting solution to attract the visitor's attention - page scrolling is made in the form of two panels, one of which slides up and the other down, opening the next block. It also works great on all, even very outdated browsers.
A very original plugin that I think visitors will like if you have a lot of long text material.
Surely, you have heard about the wonderful Javascript library called jQuery. What exactly is jQuery?
How to make a web developer's life easier? Where to begin? jQuery makes writing Javascript fun and easier. With this library, many fairly complex aspects of Javascript can be easily implemented into any application.
Today's lesson will tell you how to get started with jQuery and how to write your first script.
What is jQuery?
jQuery is a very lightweight Javascript library (some call it a framework) that takes the headache out of writing Javascript code. It has a lot of very powerful features, such as DOM tracking, adding beautiful effects and animations to elements, super simple Ajax techniques and methods. On the main page of the jQuery site, the most accurate description, in my opinion:
jQuery is a fast and concise library that simplifies event handling, animation, and Ajax interaction for faster web development. jQuery is designed to change the way JavaScript is written.
What are the benefits of jQuery?
Let's take a quick look at some of the advantages and properties of this framework:
The amount of code (required for the script to run) is significantly reduced compared to JavaScript, which in turn means less time spent and more readable code. The rest of the article will look at some examples.
Much easier to understand the code (unlike JavaScript). In our world, the sooner you finish the programming process, the more time you can devote to other goals.
Very convenient documentation and an active community, always ready to help if necessary.
Using Ajax becomes much easier. You only need 5 lines of code (sometimes less) to create a simple Ajax request.
A huge number of plugins with which you can do almost anything.
jQuery is fun :)
How to start?
First of all, you need to visit the main page of the official jQuery website and download the latest version of this framework. After downloading, you need to upload this file to your hosting, and write a link to this file in the header of the document.
Alternatively, you can use the help of the great Google and put a link to their server, where the latest versions of any frameworks are always located. The necessary link can be found.
Is the document ready?
To execute our first jQuery script, we need to wrap our entire script into a function. This function will be executed when the DOM is completely ready (when “the document is ready” - literal translation from English). Note that this is very similar to the popular 'onload' event, but is not the same. Let's look at an example:
$(document).ready(function())( //Code here ));
Above we are telling jQuery to execute any code inside the function, with the DOM completely ready. This has its advantages, despite the fact that it may not be clear to many. First of all, using this technique, we completely separate Javascript from HTML. Secondly, we do not need to wait for the page to fully load, the DOM is enough to load.
For lazy coders, or for those who count every character, you can further shorten the code above:
$(function())( //Code here ));
Your first jQuery script
We already know how to reference the library. We also understand a little about the document.ready function. Now it's time to write a simple script.
Let's make it as simple as possible. For this example, let's make a page with text and a quote at the end. We want to show the quote only if the user clicks on the button. Take a look below at the code required for this:
$(document).ready(function())(
var myQuote = $("#my_quote");
myQuote.hide();
$(".button").click(function())(
myQuote.show(500);
});
});
Let's take a closer look at the entire code.
As mentioned above, we put all the code to be executed inside the $document.ready() function.
We assign the id of our quote (my_quote) to the myQuote variable. Now we have access to the quote with id my_quote.
That's all. When you press the button for 0.5 seconds, a quote will be shown. Very easy, isn't it?
To be continued....
Thank you for your attention! All the best!
