About the test

The jQuery online test assesses knowledge of programming in the JavaScript language and features of the jQuery library through a series of live coding questions.

The assessment involves solving work sample tasks such as:

  • Handling user events and manipulating DOM to build responsive web pages.
  • Using jQuery selectors to select proper HTML elements.
  • Initiating and handling asynchronous events.

A good Web front-end or JavaScript developer working with jQuery needs a solid understanding of the JavaScript programming language and the ability to use the functionality of the jQuery library to write maintainable code that works on all browsers.

Sample public questions

7 min

An HTML div element contains a list of the most endangered species for each continent.

        <li data-continent="North America">California condor</li>
        <li data-continent="Europe">Cave bear</li>

Implement the function endangeredSpecies that returns the species's name for a particular continent.

For example, endangeredSpecies("North America") should return "California condor".

DOM Manipulation
Event Handling

A website needs a list where users can rank their favorite foods. Write the setup function, which should register click handlers on all Up! and Down! buttons. The Up! button should move the list item one place up in the list, while Down! button should move the list item one place down in the list.

Clicking the Up! button for the top list item or clicking the Down! button for the last list item should not have any effect on the list.

For example, consider this code:

document.body.innerHTML = `<ol>
  <li><button class="up">Up!</button>Taco<button class="down">Down!</button></li>
  <li><button class="up">Up!</button>Pizza<button class="down">Down!</button></li>
  <li><button class="up">Up!</button>Eggs<button class="down">Down!</button></li>


If the button Up! button in Pizza list item is clicked, Pizza should be the first item in the list, while Taco should be the second item.

Sample candidate report

What others say

Decorative quote

Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
