<p>Click the Start button to output "Hello" once every 2 seconds.</p>

<p>In this example, we also output the parameters that were passed to the alertFunc() function (does not work in IE9 and earlier).</p>

<button onclick="myStartFunction()">Start</button> <button onclick="myStopFunction()">Stop</button>

<script>
var myVar;

function myStartFunction() {
  myVar = setInterval(alertFunc, 2000, "First parameter", "Second parameter");
}

function alertFunc(param1, param2) {
  document.getElementById("demo").innerHTML += "Hello ";

document.getElementById("demo2").innerHTML = "Parameters passed to alertFunc(): <br>" 
  + param1 + "<br>" + param2 + "<br>";
}

function myStopFunction() {
  clearInterval(myVar);
}
</script>
