`, to hold the quiz content. Inside this container, you can add elements to display the question, options, and a submit button.

Storing Quiz Data

To store the quiz questions and options, you can use JavaScript arrays or objects. Each question can be represented as an object with properties for the question itself and an array of options. Additionally, you can include a property to store the correct answer.

Example:
“`javascript
const quizData = [
{
question: “What is the capital of France?”,
options: [“Paris”, “London”, “Berlin”, “Madrid”],
answer: “Paris”
},
{
question: “Who painted the Mona Lisa?”,
options: [“Leonardo da Vinci”, “Pablo Picasso”, “Vincent van Gogh”, “Michelangelo”],
answer: “Leonardo da Vinci”
},
// Add more questions…
];
“`

Displaying Quiz Questions

To display the quiz questions and options, you can use JavaScript to dynamically update the HTML elements created earlier. You can start by selecting the necessary elements using their IDs and then updating their content using JavaScript.

Example:
“`javascript
const questionElement = document.getElementById(“question”);
const optionsElement = document.getElementById(“options”);

function displayQuestion(question) {
questionElement.textContent = question.question;
optionsElement.innerHTML = “”;

question.options.forEach(option => {
const li = document.createElement(“li”);
li.textContent = option;
optionsElement.appendChild(li);
});
}

// Call the displayQuestion function with the first question
displayQuestion(quizData[0]);
“`

Handling User Interaction

To allow users to select an option and submit their answer, you can add event listeners to the options and submit button. When an option is clicked, you can highlight it to indicate the user’s choice. When the submit button is clicked, you can check if the selected option matches the correct answer and provide feedback to the user.

Example:
“`javascript
const options = optionsElement.getElementsByTagName(“li”);
const submitButton = document.getElementById(“submit”);

function handleOptionClick(event) {
// Remove any previously selected option
Array.from(options).forEach(option => {
option.classList.remove(“selected”);
});

// Highlight the clicked option
event.target.classList.add(“selected”);
}

function handleSubmitClick() {
const selectedOption = optionsElement.querySelector(“.selected”);

if (selectedOption && selectedOption.textContent === quizData[0].answer) {
alert(“Correct answer!”);
} else {
alert(“Wrong answer!”);
}
}

// Add event listeners
Array.from(options).forEach(option => {
option.addEventListener(“click”, handleOptionClick);
});

submitButton.addEventListener(“click”, handleSubmitClick);
“`
