Question

I want a simple JavaScript countdown which counts to 5 and then stops. I want to show the current value (1,2,3,4,5)

I tried:

function countdown() {
    jAlert('test', i);
    i++;
    if (i >= 5) {
        clearInterval(aktiv);
    }
};
var aktiv = setInterval('countdown()', 1000);
var i = 0;

But every time I insert that i in to jAlert it wont work any more. What is wrong there?

Answer 1

var $i = 0;
var $interval = setInterval(function()
{
    if (++$i === 5)
        clearInterval($interval);

    jAlert('test', $i);
},
1000);
