I came across http://rindovincent.blogspot.com/p/javascript.html where there was a simple Javascript program to find whether the number is odd or even. I am pasting the same code with permission here.
var n = prompt(“Enter a number to find odd or even”, “Type your number here”); n = parseInt(n); if (isNaN(n)) { alert(“Please Enter a Number”); } else if (n == 0) { alert(“The number is zero”); } else if (n%2) { alert(“The number is odd”); } else { alert(“The number is even”); }
Why not just
function isEven(value) {
return (value%2 == 0);
}
And the PHP version only needs an extra dollar sign:
function isEven($int){
return ($int%2 == 0);
}
In these times, I can assume most webdevvers use a javascript library like jQuery or similar. These libraries have functions like isEven built in.
For those who don’t use such libraries: great snippet ;)
