It's pretty straightforward:

setInterval(function(){
    //your code here
}, 5000);

Use setInterval()

In the below example, 5000 represents 5 seconds.

<script type="text/javascript">
    function fun() {
        var exam=new XMLHttpRequest();
        exam.onreadystatechange=function() {
            if(exam.readyState==4) {
                document.getElementById("content").innerHTML=exam.responseText;
            }
        }
        exam.open("GET","rat_test.php?name=pramod",true);
        exam.send(null);
    }
    setInterval(function(){
        fun();
    },5000);
</script>

x = 5; // Seconds
setInterval(fun, x * 1000);

The above code would run the fun function every 5 seconds. The reason we times x by 1000 is because it takes it as milliseconds.

So 1000 = 1 second, 2000 = 2 seconds and so on...

That would be true if we were calling it, we are not. – Cameron Sep 12 '14 at 18:58

you can use this Jquery function :

//x in second 
var sec=x

setInterval(function(){fun()}, x*1000);

You can use setInterval function

var x = setInterval(function(){
  //Your code
},200); //miliseconds to interval

and if you want to stop it

clearInterval(x);
