PHP AJAX Refresh Help

[DaemonProjects]

Hey guys, im having a little problem refreshing my ajax code. I dont want to use a meta tag for this and have the page refresh each time. So im trying to use ajax, now this is the first time using it ajax so bare with me.

here is my code, for some reason it will not refresh and grab the new data from my php page.

<script language="Javascript">
var sinterval = 5;
var _sInterval;
function createRequestObject() {
    var ro;
    var browser = navigator.appName;
    if(browser == "Microsoft Internet Explorer"){
        ro = new ActiveXObject("Microsoft.XMLHTTP");
    }else{
        ro = new XMLHttpRequest();
    }
    return ro;
}

var http = createRequestObject();
var getit = "crypt";

function sndReq(action) {
    http.open('get', 'comment_box2.php?action='+action);
    http.onreadystatechange = handleResponse;
    http.send(null);
}

function handleResponse() {
    if(http.readyState == 4){
        var response = http.responseText;
        var update = new Array();

    if(response.indexOf('|' != -1)) {
        update = response.split('|');
        document.getElementById(update[0]).innerHTML = update[1];
    }
}
}

function force_shout_update() {
	setTimeout("sndReq('go')",1000);
}

window.onload=force_shout_update();
</script>

this code gets the data but just wont refresh ever second or 5 seconds etc..

setTimeout("sndReq('go')",1000); doesnt seem to work

NOTE:
works with

function force_shout_update() {
setTimeout("sndReq('go')",5000);
}

window.setInterval("force_shout_update()",1000);

[ednark]

your code as posted will call force_shout_update once at page load

that will wait 1 second before sending off single ajax request

this behavior does not do any constant refreshing

function force_shout_update() {
	setTimeout("sndReq('go')",1000);
}
window.onload=force_shout_update();

your note show you konw how to get a result more like you asked for with the setInterval function

function force_shout_update() {
  setTimeout("sndReq('go')",5000);
}
window.setInterval("force_shout_update()",1000);

however, this will call force_shout_update every second and each force_shout_update will wait 5 seconds and call sendRed, which will really just be calling it every second

sec 1 : force_shout_update_1
sec 2 : force_shout_update_2
sec 3 : force_shout_update_3
sec 4 : force_shout_update_4
sec 5 : force_shout_update_5
sec 6 : force_shout_update_6, sendReq_1
sec 7 : force_shout_update_7, sendReq_2
sec 8 : force_shout_update_8, sendReq_3
sec 9 : force_shout_update_9, sendReq_4
sec 10 : force_shout_update_10, sendReq_5

i believe you want your code to look something like this

var _shout_interval = null
function start_shout_updates( interval_in_seconds )
{
        stop_shout_updates();
	_shout_interval = setInterval("force_shout_update()", interval_in_seconds * 1000 );
}
function stop_shout_updates()
{
	clearInterval(_shout_interval);
}
function force_shout_update() {
	sndReq('go');
}
window.onload = start_shout_updates
