jQuery UI Components Basics Quiz Quiz

Explore essential concepts of jQuery UI components with this quiz, covering widgets, interactions, options, and event handling. Deepen your understanding of how to enhance web interfaces using popular jQuery UI features and best practices.

1. Identifying a jQuery UI Widget

   Which of the following is a standard jQuery UI widget used for displaying multiple panels with clickable headings, such as organizing FAQs or step-by-step guides?

   1. Draggable
   2. Expander
   3. Accordion
   4. Selector

   Explanation: Accordion is the correct answer because it is a built-in jQuery UI widget that organizes content into expandable and collapsible sections with header labels. Draggable is an interaction feature, not a widget for grouped panels. Selector is not a jQuery UI component, and Expander, while similar in purpose, is not the accurate jQuery UI widget name. Choosing Accordion ensures you use the standard UI tool for multi-panel content.

2. Initializing a Component

   How would you initialize a date picker on an input field with jQuery UI, given an input with the ID 'birthday'?

   1. $('#birthday').datepicker();
   2. $('#birthday').datePicker();
   3. $('#birthday').calendar();
   4. $('#birthday').pickerdate();

   Explanation: The correct way to initialize the date picker is $('#birthday').datepicker(); because 'datepicker' matches the standard jQuery UI widget name and syntax. The other options use incorrect method names: 'calendar', 'datePicker', and 'pickerdate' are not valid initializers, which would cause errors or unexpected results. Using the exact 'datepicker' method ensures compatibility with the library.

3. Customizing Component Behavior

   Which option correctly configures a jQuery UI slider to have a minimum value of 10 and a maximum of 50?

   1. { start: 10, end: 50 }
   2. { from: 10, to: 50 }
   3. { value: 10, maximum: 50 }
   4. { min: 10, max: 50 }

   Explanation: The correct configuration uses the properties 'min' and 'max', as in { min: 10, max: 50 }, because these are the standard option names for a slider's range. The other options use incorrect naming conventions: 'value', 'maximum', 'from', 'to', 'start', and 'end' are not recognized by the jQuery UI slider and would not configure the range correctly. Using correct property names ensures the slider functions as intended.

4. Handling Events with jQuery UI

   Suppose you want to perform an action when a jQuery UI dialog is closed. Which event should you listen for?

   1. exit
   2. detach
   3. close
   4. hide

   Explanation: Listening for the 'close' event lets you execute code when the dialog is closed, as this is the standard event triggered in that scenario. 'Hide' may seem related, but it is not the event name used by the dialog component. 'Exit' and 'detach' are not defined events for dialog closures and would not work as intended. Using 'close' ensures your code responds to the correct lifecycle event.

5. jQuery UI Interactions

   If you want an element to be repositionable using the mouse, which jQuery UI interaction method should you apply?

   1. sortable
   2. swipeable
   3. draggable
   4. toggleable

   Explanation: The 'draggable' method enables mouse-based repositioning of elements, making it the correct interaction for this requirement. 'Toggleable' is not a standard interaction method, while 'sortable' allows for sorting items in a container, not free movement. 'Swipeable' is unrelated and not a built-in feature. Only 'draggable' provides the desired repositioning functionality.
