Javascript Random Number?

Question

I have the following script:

Timer=0;
function countdown(auctionid){
    var auctions;
    var divs;

    Timer=Timer+1;

    if((Timer%10==\"0\")||(Timer==\         


        

Answer 1

See the answers to this question which also allows you to set the seed value.

Answer 2

You want to use the random() function. There is no version that returns an integer unfortunately, only a float between 0 and 1, so you'll need to do a few operations. Try the following:

var randomNum = Math.floor(Math.random() * 10) + 2;

This should generate a random integral number between 2 (inclusive) and 12 (exclusive). Change 10 to 11 if you want the 12 to be inclusive, of course.

Answer 3

Using the Web Crypto api.

console.log(

  crypto.getRandomValues(new Uint32Array(1))[0] ,

  crypto.getRandomValues(new Uint16Array(1))[0] ,
  
  crypto.getRandomValues(new Uint8Array(1))[0]
  
)
