javascript setInterval function not working

Question

I want to call a function for every half minute. i am using the following code. The function is not getting triggered.

Code:

window.setInterval('progress()', 10000);

Geetha.

10000 milliseconds is 10 seconds... Does the function progress exist? — Dror

Every half min would be 30,000 miliseconds

Example ...

refreshId = setInterval(myfunction(), 30000);

In jQuery you'd do something like ...

$(document).ready(function(){

    var refreshId = setInterval(myfunction(), 30000);

});

Or if you want to put your function within your refresh code ...

$(document).ready(function(){

    var refreshId = setInterval(function() {
        $("#myid").load('/mypage.html?update='+ Math.random());
    }, 30000);

});

This is wrong... it will call myfunction() as part of the setup of the interval, and use the return value. It should be providing a reference to myfunction instead: setInterval(myfunction,30000);

I think the setInterval method may somehow fail to find the definition of the progress function.

Have you tried invoking setInterval with the function object directly?

window.setInterval(progress, 10000);
