setInterval with an Array

Question

I'd like to use the setInterval function in jQuery in order to create an alert with the content of one array every 4 seconds. However my alerts show all the values of my array within a short amount of time and it stops for 4 seconds after having displayed all the values.

$.each(['html5', 'EDM', 'Coca Cola', 'creativity'], function(id,value) {
    setInterval(function(){
        alert(value);
    }, 4000);
});

In this case, I'd like to display something like : Alert('html5') - 4 seconds - Alert('EDM') - 4 seconds - Alert('Coca Cola') - 4 seconds - Alert('creativity') - 4 seconds - Alert('html5') - 4 seconds - Alert('EDM') - 4 seconds - ...

Answer 1

Move the setInterval from the loop.

var arr = ['html5', 'EDM', 'Coca Cola', 'creativity'];
var index = 0;
setInterval(function() {
    console.log(arr[index++ % arr.length]);
}, 4000);​
