JavaScript and jQuery – functions, operations and management

Training process

Training needs analysis

If you have specific requirements regarding the training programme, we will carry out a training needs analysis for you. This will guide us on which aspects of the programme should receive greater emphasis, so that the training programme meets your specific needs.

What will you gain?

Writing your first scripts - You will learn how to build simple JavaScript scripts on your own, use data types, variables and operators, and start creating working logic instead of relying on trial and error.

Using functions effectively - You will understand how to define and call functions and how to split code into smaller parts, so you can write solutions faster, extend them more easily and avoid repeating logic.

Working with text and data - You will master string and array operations, so you can search text, replace content, split data and read values that are commonly needed in everyday scripting tasks.

Building program logic - You will practice conditionals and loops, which will help you create code that reacts to different situations, processes data step by step and automates repetitive tasks.

Understanding the browser better - You will get familiar with objects such as window, document, history and location, making it easier to understand how scripts work with the browser and affect a web page.

Changing pages with DOM and jQuery - You will learn how to select page elements, read their content, modify attributes, and remove or replace HTML fragments, so you can make real interface changes on a website.

Handling user events - You will learn how to respond to mouse clicks and keyboard actions, so you can start building interactive features that react to what the user does on the page.

Simple effects and animations - You will master basic jQuery animations such as showing, hiding, fading and moving elements, so you can enrich pages with clear, dynamic visual effects.

What are the prerequisites for participating in the training?

Basic computer use - You should be comfortable using a computer, keyboard and mouse, launching programs and switching between windows, so you can focus on the exercises rather than the device.

Basic browser skills - You should be able to use a web browser efficiently, open websites and move around them, because the training focuses on how scripts work in a web environment.

Understanding page structure - You should have a basic idea of what a web page is and what it is made of, so it will be easier for you to understand the DOM and HTML element manipulation.

Readiness to work with code - You should be ready to read short code snippets and type them on your own, because the training is practical and built around step by step hands-on exercises.
