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
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.
For example, consider this code:
document.body.innerHTML = `<ol>
<li><button>Up!</button>Taco<button>Down!</button></li>
<li><button>Up!</button>Pizza<button>Down!</button></li>
<li><button>Up!</button>Eggs<button>Down!</button></li>
</ol>`;
setup();
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.
The createProductCodeForm function is used to create a new form that accepts a product code from a user.
The current version of the form contains the hint: 'The product code can be found on the label'. This hint is currently always visible to the user.
Improve the form so that the hint is only rendered when the input element is the focused element.

What others say
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.
