<script>
var intervalVariable=setInterval(function(){
   //Your operation goes Here
  },1000); // executes every 1000 milliseconds(i.e 1 sec)

function stopTimer()
{
   clearInterval(intervalVariable); // To clear TimerInterval/stop the setInterval Function
}
</script>

var interval = window.setInterval(function() {
  console.log("foo");
}, 1000);

And stop

window.clearInterval(interval);

You can use setInterval to do this.

See: https://developer.mozilla.org/en/DOM/window.setInterval

var int = self.setInterval(askQuestion,1000);

function askQuestion() {
 // do something... code to be implemented.
}

Will be call askQuestion() every 1000 milliseconds (1 seconds) for example..

The simplest way would be with setInterval:

setInterval(function() {
    console.log("run every second");
}, 1000);

This will run the given code at the specified time interval over and over.
