Sum of primes

Click the button to determine sum of the prime numbers between number X and number Y (inclusive).

Number X:

Number Y:

//

// Write a program that computes the sum of the prime numbers bewteen two inputs, X and Y.

//

// What's a prime number?

// In mathematics, a prime number is any number that has exactly two positve divisors: 1 and itself.

//

// For example, 7 is prime.

// 7 / 1 = 7

// 7 / 2 = 3.5 (not a divisor)

// 7 / 3 = 2.333... (not a divisor)

// 7 / 4 = 1.75 (not a divisor)

// 7 / 5 = 1.4 (not a divisor)

// 7 / 6 = 1.1666... (not a divisor)

// 7 / 7 = 1

//

// 7 has only two divisors: 1 and 7.

//

//

// If a user provides any input that is not a natural number, then the function should

// return the error message: "Bad data. Try again."

$('#btn_1').click(function(){

var numx = $('#textEntered1').val();

var numy = $('#textEntered2').val();

var message = sumOfPrimes(numx, numy);

$('#textDisplayed1').html(message);

})

7. Complete the sumOfPrimes function. Notice that sumOfPrimes takes two parameters, numx and numy. In this assignment, it important to ensure that both numx and numy are integers. That is why the lines of code using parseInt() have been included. 8. Test your work. A sample screenshot is shown below. index.html X +
