I want to check if a number is a prime number by typing it in a box, then click on a button and get the value is prime number or is not a prime number. I have the following code, but for some reason I can't figure it out why it is not working - I get the value is prime number for any number I tried.
function isPrimeNumber() {
var n = document.getElementById("n").value;
for (var i = 2; i < n; i++) {
if (n % i === 0) {
document.getElementById("result").value = "not a prime number";
}
}
document.getElementById("result").value = "prime number";
}
<form>
<p>
<input type="text" id="n">
<input type="button" value="Check if I am prime!&quo
