Imagine you are building a pricing page with a table layout, and you are asked to ensure that specific cells are highlighted dynamically based on user interaction. How would you implement this while keeping the table layout clean and accessible?

  • Hardcode the highlighted cells. 
  • Use Flash animations to highlight cells. 
  • Use a JavaScript event listener to add or remove CSS classes based on user actions. 
  • Use inline styles to change cell background color. 
By using JavaScript event listeners combined with CSS classes, you can dynamically highlight cells based on user interaction without compromising the clean and semantic structure of the table. Inline styles can clutter the HTML, while hardcoding lacks flexibility. Flash is outdated and not recommended for modern web design.

How do you create a link that navigates to a specific section within the same HTML document?

  • Embed a JavaScript function. 
  • Link the section as an external document. 
  • Use a # followed by the section's ID as the href value. 
  • Use a class attribute with the section name. 
To navigate to a specific section within the same HTML document, anchors are utilized. An anchor is created using the tag with the href attribute containing a # followed by the ID of the target section. For instance, if there's a section with the ID section1, a link to this section would look like Go to Section 1. The target section would have the ID defined, like

...

. Clicking the link would take the user directly to that section.

You have a form that has multiple submit buttons for different actions (e.g., Save, Submit for Review). How would you utilize buttons and JavaScript to ensure that each button submits the form differently, and what considerations should you have for user experience and data integrity?

  • Assign different names or values to the buttons and use JavaScript event listeners to handle different submit actions. 
  • Place each button in a different form and duplicate the input fields. 
  • Use only one button and prompt users to choose an action via a dropdown. 
  • Use the same name and value for all buttons and distinguish actions based on button color. 
Different actions can be handled by giving each submit button a unique name or value. By using JavaScript event listeners, you can detect which button was clicked and handle the form submission accordingly. This approach ensures data integrity by allowing specific actions to be taken based on the user's choice. It also enhances user experience by providing clear, direct actions without redundant steps or confusion.
