Generating random numbers in Javascript

Hi..

I want to generate random numbers (integers) in javascript within a specified range. ie. 101-999. How can I do that. Does Math.random() function supports range parameters ?

Answer 1

The function below takes a min and max value (your range).

function randomXToY(minVal,maxVal)
{
  var randVal = minVal+(Math.random()*(maxVal-minVal));
  return Math.round(randVal);
}

Use:

var random = randomXToY(101, 999);

Hope this helps.
