JavaScript - jQuery interval

Question

I am using JavaScript with jQuery. I have the following script to alert hi every 30 seconds.

$(document).ready( function() {
    alert(\"hi\");
         


        

Answer 1

Well, there probably is a way of doing it in just one call..

setInterval(
    (function x() {
        alert('hi');
        return x;
    })(), 30000);

Another solution would be to use arguments.callee, but as it is now deprecated, it is generally not recommended to use it.

setInterval(
    (function() {
        alert('hi');
        return arguments.callee;
    })(), 30000);
