Randomize setInterval ( How to rewrite same random after random interval)

Question

I\'d like to know how to achieve: generate a random number after a random number of time. And reuse it.

function doSomething(){
     // ... do something.....         


        

Answer 1

Just setup interval each time you rand (and clear it first)

function doSomething(){
     // ... do something.....
}

var i;
var rand = 300;

function randomize() {
    doSomething();
    rand = Math.round(Math.random()*(3000-500))+500; 
    clearInterval(i);
    i = setInterval('randomize();', rand);
}

i = setInterval('randomize();', rand);

or try using setTimeout (and setting again after randing)
