12.6 Homework Assignment

Objective:

Students will create a JavaScript script that prompts the user for their age and uses if-else statements to determine what legal activities the user can participate in, such as voting, driving, drinking alcohol, etc.

Task:

  1. Write a JavaScript script that:

    • Prompts the user to input their age using prompt().

    • Uses if-else statements to determine the user's eligibility for certain legal activities based on their age.

    • Outputs the results using console.log() to display the legal activities the user can participate in.

  2. Example Activities to check for:

    • Vote (18 and above)

    • Drive (16 and above)

    • Religion (20 and above)

    • Drink alcohol (21 and above)

    • Senior citizen benefits (65 and above)

Step-by-Step Instructions:

  1. Create an HTML file (e.g., age_eligibility_homework.html) and write the following script to ask for the user's age and determine eligibility for various activities.

    Example Code:

    <!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Legal Activities Eligibility</title>
</head>
<body>
  <h1>Check the Console for Eligibility Results</h1>
  
  <script>
    // Ask the user for their age
    let age = prompt("Please enter your age:");
    age = parseInt(age);  // Convert the input to an integer

    // Check eligibility for various activities
    if (age >= 65) {
      console.log("You are eligible for senior citizen benefits.");
    } 
    
    if (age >= 21) {
      console.log("You are eligible to drink alcohol.");
    } 
    
     if (age >=20) {
      console.log("You are eligible to have religion.");
    } 
    
    if (age >= 18) {
      console.log("You are eligible to vote.");
    } 
    
    if (age >= 16) {
      console.log("You are eligible to drive.");
    } 
    
    if (age < 16) {
      console.log("You are not eligible to drive, vote, have religion or drink.");
    }
  </script>
</body>
</html>

  2. Open the file in a browser:

    • Open the HTML file in a browser and use Developer Tools (F12 or right-click and select Inspect > Console) to view the results after entering an age.

  3. Testing:

    • Input different ages (e.g., 12, 16, 18, 21, 65) and observe how the script outputs the appropriate messages for each legal activity.

    • Ensure that the script correctly handles different age groups and displays the corresponding activities.

Challenge:

  • Modify the script to include additional activities and show the result in web page document using id in div element , such as:

    • Working part-time (14 and above).

    • Running for president (35 and above).

    Example Code for Challenge:

    if (age >= 35) {
  console.log("You are eligible to run for president.");
} 

if (age >= 14) {
  console.log("You are eligible to work part-time.");
}

Homework Submission:

  • Save your HTML file and submit it to the instructor.

  • Ensure that the script runs correctly and outputs the appropriate messages based on the age entered.

Expected Outcome:

Students will demonstrate their understanding of if-else statements by writing a script that checks user input and determines eligibility for various legal activities. They will also practice using prompt() and console.log() to interact with the user and display results.
