JavaScript generate random number except some values

Question

I\'m generating random numbers from 1 to 20 by calling generateRandom(). How can I exclude some values, say 8 and 15?

function generateRandom(mi         


        

Answer 1

You can build an array dynamically. Depending on where you are getting the excluded numbers. Something like:

var excluded = [8, 15];
var random = [];
for(var i = min; i <= max; i++) {
  if(excluded.indexOf(i) !== -1) {
    random.push(i);
  }
}

Then use the tips found in the answer for this post: How can I generate a random number within a range but exclude some?. Should get you to where you want to go.
