Var help

Question

Can you make a variation go radomly between numbers?
Example (this is very wrong but i want you to get the picture):
var a = 10-20;
document.getElementById(“ID”).innerHTML = a;
I know this is wrong but is it possible to do it even in a longer way of coding it? If its not possible its ok to tell me.

Answer 1

Something like this will do the trick. May not be the simplest way, but I'm still learning :)

Note: I have set an infinite interval going. You can stop it using clearInterval(changeIt); within an 'if' statement within the changeIt function.

Answer 2

The standart formula for that is
a = Math.floor(min+(max-min)*Math.random());

Answer 3

Var a = Math.floor(Math.random() * 11) + 10;
this will generate a random integer value, between 10 and 20 (including 10 and 20)

Answer 4

@Will Cavalcanti, your solution doesn't include 10
What you might want is floor(rand()*11)+10) instead

Answer 5

I'm not absolutely certain to get what you mean, do you want a randomly chosen number between, here, 10 and 20?

Answer 6

yup my mistake

Answer 7

You're welcome! :')

Answer 8

Thanks everyone!

Answer 9

So the value of that is now random between that number?
