javascript setinterval with random time -

i have setinterval function alert:

setinterval(function(){     alert('oo'); }, 5000); 

but change (5000) interval each time interval runs alert() - i'd have randomly selected between 5 - 10 seconds. idea how it?

you should use settimeout set interval after function should executed.

function myfunction() {    var min = 5,      max = 10;    var rand = math.floor(math.random() * (max - min + 1) + min); //generate random number between 5 - 10    alert('wait ' + rand + ' seconds');    settimeout(myfunction, rand * 1000);  }    myfunction()
