Step 2: Styling the Elements
Use CSS to style the elements for a visually appealing appearance. Apply rounded borders, padding, and font sizes to the input textbox, button, and dropdown menu. Choose colors that complement your website's design scheme.
Step 3: Implementing the JavaScript Functionality
Now, let's focus on the JavaScript part. Create a function named addToDropdown(). Inside this function, retrieve the textbox and dropdown elements using their respective IDs. Get the value entered in the textbox and trim any leading or trailing white spaces.
Step 4: Adding Values to the Dropdown
Check if the value is empty. If it is, exit the function to prevent adding empty options. Otherwise, create a new option element dynamically. Set the text and value of the option to the entered value. Append the option to the dropdown menu using the add() method. Finally, clear the textbox value to prepare for the next input.
