jQuery and Interactive Web Pages: Free Course

About this course

Study jQuery and Interactive Web Pages through this free English video course from freeCodeCamp. The classroom brings together all 10 public recordings from the selected source curriculum, totaling approximately 59m. You can watch the teaching sequence, search the lesson list and keep track of the recordings you have completed. The course focuses on the subject named in its title. Its value comes from following the explanations and making your own small practice attempts, with enough time to inspect the result and explain the decisions involved.

Course Overview

Ten ordered lessons cover selection, events, effects, DOM manipulation, traversal and Ajax, concluding with vanilla-JavaScript comparison.

The source lesson list includes “Getting started with jQuery (tutorial) – Beau teaches JavaScript”, “jQuery: add and remove DOM elements – Beau teaches JavaScript”, “jQuery vs vanilla JavaScript – Beau teaches JavaScript”. The classroom retains their original titles and positions. Introductions, supplementary explanations and complete-course recordings remain present whenever they are part of the source. A repeated recording is retained at each original position, allowing the course to be checked against the published teaching sequence.

Selection and interaction

Start with getting started and events. Identify the selected elements and explain how an event handler changes a visible part of a page.

Effects and content

Follow effects, animation and get/set methods. Separate a presentation change from a change to stored or displayed information, and inspect the result in the browser.

DOM structure

Study adding, removing, styling and traversing elements. Trace the relationship between parent and child nodes before applying a change to a group of elements.

Requests and comparison

Follow Ajax and the concluding comparison. Explain how a response reaches the interface and identify which tasks can also be expressed with browser APIs.

Who is this for?

This course suits learners who want the specific subject described above and who can work at the stated level. It is also useful as a recorded reference when revisiting a concept or comparing a practice attempt with a demonstrated example. Beginners should give the foundational explanations time before moving to more elaborate applications. Experienced learners can use the lesson names to locate a topic, then inspect the surrounding context before applying a technique.

Before you start

Basic HTML, CSS and JavaScript are recommended. Use a small isolated page with a compatible jQuery version for practice, and inspect the DOM as you follow the recorded examples.

Put the lessons into practice

Create a fictional reading list with a filter and an expandable description. Use an event handler to change a class and add one new item. Inspect the resulting DOM and explain how traversal selects the intended element. Sketch an Ajax response using sample local data, then rewrite one small operation with vanilla JavaScript and compare the two approaches.

Treat this suggested exercise as independent practice provided by WikiFree. Keep a short working note containing your inputs, assumptions, result and one point you still need to check. Revisit the relevant recording when a step is unclear, then attempt a small variation without following the demonstration line by line. A result you can explain and reproduce is a more useful study outcome than simply recognizing a familiar term. The exercise is not submitted to an instructor for grading.

Certificate / Assessment

Watching these public recordings and using WikiFree completion tracking does not award a certificate, academic credit, an examination voucher or instructor assessment. The video curriculum is the material included here. Separate platform assignments, credentials and paid services are not part of video viewing. Use the practice output to review which concepts you can explain, which steps you can repeat independently and which questions need another look at the teaching.
