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

Wrap your code in a function. Then, pass the function as a first argument to setInterval, and call the function:

$(document).ready( function() {
    //Definition of the function (non-global, because of the previous line)
    function hi(){
        alert("hi");
    }

    //set an interval
    setInterval(hi, 30000);

    //Call the function
    hi();
});
