hi all.
i hope someone could help me.
i'm trying to build a bidding site using ajax, and php.
what i want to do is that: when the bid time is over 5 minutes, the "div" i've placed will refresh every 10 seconds, and when its under it will refres every 5 seconds.
i've tried everything i know but i still cant make it work.
the best i got is that i have to refresh the whole site using the F5 button and then it changed, but i want it to change automaticly.
this is my main html/php code:
<?php
session_start();
include("database2.php");
include("login.php");
$_SESSION['timeout']=1;
?>
<html>
<head>
<script language="javascript" type="text/javascript">
<!--
//Browser Support Code
var i=false;
function check()
{
t=null;
clearTimeout(t);
<?php
if($_SESSION['timeout']==1)
{
?>
ajaxFunction2();
t=setTimeout("check()",10000);
<?php
}
else
if($_SESSION['timeout2']==2)
{
?>
ajaxFunction2();
t=setTimeout("check()",5000);
<?php
}
?>
}
function ajaxFunction(){
var ajaxRequest; // The variable that makes Ajax possible!
try{
// Opera 8.0+, Firefox, Safari
ajaxRequest = new XMLHttpRequest();
} catch (e){
// Internet Explorer Browsers
try{
ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try{
ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e){
// Something went wrong
alert("Your browser broke!");
return false;
}
}
}
// Create a function that will receive data sent from the server
ajaxRequest.onreadystatechange = function(){
if(ajaxRequest.readyState == 4){
var ajaxDisplay = document.getElementById('ajaxDiv');
ajaxDisplay.innerHTML = ajaxRequest.responseText;
}
}
ajaxRequest.open("GET", "ajax2.php", true);
ajaxRequest.send(null);
}
function ajaxFunction2(){
var ajaxRequest; // The variable that makes Ajax possible!
try{
// Opera 8.0+, Firefox, Safari
ajaxRequest = new XMLHttpRequest();
} catch (e){
// Internet Explorer Browsers
try{
ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try{
ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e){
// Something went wrong
alert("Your browser broke!");
return false;
}
}
}
// Create a function that will receive data sent from the server
ajaxRequest.onreadystatechange = function(){
if(ajaxRequest.readyState == 4){
var ajaxDisplay = document.getElementById('ajaxDiv');
//ajaxDisplay.innerHTML = ajaxRequest.responseText;
}
}
ajaxRequest.open("GET", "ajax3.php", true);
ajaxRequest.send(null);
//t=null;
}
