We have a form with 2 fields and a button. We want on button click to output random int number (like 3, 5 or 33) which would lie between int A and int B? (no use of jQuery or anything like it is required)

Reset to default 13You can use Javascript Math.random
function randomInRange(start,end){
return Math.floor(Math.random() * (end - start + 1) + start);
}
Use something like Math.floor(Math.random()*(intB-intA +1)) + intA ?
Like this:
Math.floor(a + Math.random() * (b - a))
The Math.random() method returns a random floating-point number in the range [0,1) — that is, between 0 (inclusive) and 1 (exclusive).
