 Posted: 13.07.2007 14:42 Post subject: Pokušaj AJAXA |
  |
|
Pokušavam malo petljati s ajaxom i našao sam na netu tutorial kako da komuniciram s php skriptom, problem je sljedeći, sve normalno radi u Firefoxu i IE 5+, ali u Operi ne (najnovijoj)
Ako netko moze pogledati i reci u cem je problem, bio bih jako zahvalan.
(Skripta traži vrijeme od servera preko php-a i vraća natrag klijentu)
Skripta se nalazi na http://thereis.myftp.org/ajax/ajax.html
A kod je ovakav
| Code: | <html>
<body>
<script language="javascript" type="text/javascript">
<!--
//Browser Support Code
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){
/*document.myForm.time.value = ajaxRequest.responseText;*/
document.getElementById("tekst").innerHTML = ajaxRequest.responseText;
setTimeout(ajaxFunction,1000);
}
}
ajaxRequest.open("GET", "serverTime.php", true);
ajaxRequest.send(null);
}
//-->
</script>
<script>ajaxFunction();</script>
<div id="tekst"></div>
</body>
</html> |
php:
| Code: | <?php
echo date("H:i:s");
?> |

nisam siguran dal ste shvatili, skripta bi trebala (setTimeout(ajaxFunction,1000) svakih sekundu prikazati novo vrijeme...
sekundu po sekundu...
u firefoxu 2.0 radi kak se spada 
| Quote: | | u operi samo stoji...kad se refresha, vrijeme je isto kao i prije |
edit: u postavkama sam prčkao po cacheu i redrawu stranice, i sad sve radi
| Quote: | | u ie7 samo stoji...kad se refresha, nema ničeg |
edit2: evo ista stvar i sa IE7, promijenio sam u Tools > Internet Options > History (Temporary files) da ne cachea nego da stalno provjerava za novi content na stranici i sad sve isto tako radi...čudno
Moram napomenuti da su sve ovo DEFAULTNE postavke programa...
Postoji li način da spriječim da se to dogodi i nekome drugom tko posjeti takvu stranicu, ili?
btw. Hvala dečki na trudu |

Budući da sam isprobavao gro stvari i skripti...ima još jedna koja po defaultu radi na Firefoxu i Operi a ne u IE7, no otkad sam uključio ono gore, radi i ova.
http://thereis.myftp.org/ajax/ajax2.html
| Code: | Firefox i Opera ok <br />
IE7 not
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script language="javascript" type="text/javascript">
var xmlHttp;
function createRequest(){
if(window.ActiveXObject){
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
}
else if(window.XMLHttpRequest){
xmlHttp = new XMLHttpRequest();
}
}
function ajax(){
createRequest();
var url = "ajax2.php?test=hello!";
xmlHttp.open("GET", url, true);
xmlHttp.onreadystatechange = StateChange;
xmlHttp.send(null);
}
function StateChange(){
if(xmlHttp.readyState == 4){
/*alert(xmlHttp.responseText);*/
document.getElementById('tekst').innerHTML = xmlHttp.responseText;
setTimeout(ajax,1000);
}}
</script>
</head>
<body>
<script>ajax();</script>
<div id="tekst"></div>
</body>
</html> |
Možete li mi reći koju je pametnije koristiti i zašto?
btw. php fajl je isti. |

Nisam probao tvoju skriptu - al ako je problem u cachiranju, mozes probati pozivati url s random brojem iza njega sto ce osigurati da ga browser ne cachira.
npr. dodas:
| Code: | | var d = new Date(); |
i jos promijenis onu jednu postojecu liniju u:
| Code: | | ajaxRequest.open("GET", "http://thereis.myftp.org/ajax/serverTime.php?"+d.valueOf(), true); |
|

Ili na serverskoj strani serviras content sa no-cache headerima. I jedan i drugi pristup imaju
svojih prednosti i mana.
php manual za no-cache headere:
| Code: | <?php
// Date in the past
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
// always modified
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
// HTTP/1.1
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
// HTTP/1.0
header("Pragma: no-cache");
echo date("H:i:s");
?> |

Oo hvala ekipa

Zanimljiv pristup, u teoriji, budem isprobao u praksi pa cemo vidjeti...jako zanimljivo, nema šta... |
Sva navedena rješenja stvarno rade, hvala lijepo svima na trudu još jednom |

Vezano uz testiranje objekta...
window.XMLHttpRequest je manje ubojit za stroj od nestane try/catch nesreće iz prvog primjera...

koliko točno manje ubojit?
već sam sve napravio sa
| Code: | try{
// Za Operu, Firefox, Safari
ajaxRequest = new XMLHttpRequest();
} catch (e){
// Za Internet Explorer
try{
ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try{
ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e){
// Ups...wtf?
alert("Vaš internet preglednik ne podržava \"XMLHttpRequest\".<br />Molimo koristite Operu 8+,Firefox 1.5+,IE 5+");
return false;
}
}
} |
kako bi to prepisao u ovo što ti predlažeš?[/quote] |

u stvari, meni je više potrebna brzina i kompaktnost koda (da ga je što manje )
a manje mi je potrebna podrška za ie manji od verzije 7
kopajući uokolo, saznao sam da ie7 podržava XMLHttpRequest i bez activeX-a tako da ovaj try/catch leti definitivno van
ukoliko će mi biti potreban support za ie manji od 7ce, namjeravam iskoristiti ovo
