Can I run two XMLHTTPRequest objects at the same time? Im able to get
one to work without problems.
If I put a call to a function inside the first ones onreadystatecha nge
function, the 2nd ones readyState is always set to 1 (loading). Ive
tried using the same XMLHTTPRequest object, and making a 2nd
XMLHTTPRequest object with the same results. Heres my code thats giving
me problems...
function RefreshChat() {
http.open("GET" ,"refreshchat.p hp",true);
http.onreadysta techange = function () {
if (http.readyStat e == 4 && http.status == 200) {
// XML
XML_result = http.responseXM L;
docNode = XML_result.docu mentElement;
msg_count = docNode.getElem entsByTagName(' message').lengt h;
i = 0;
while(i < msg_count) {
messagesNode = docNode.getElem entsByTagName(' message')[i];
datetime =
messagesNode.ge tElementsByTagN ame('datetime')[0].firstChild.dat a;
from =
messagesNode.ge tElementsByTagN ame('from')[0].firstChild.dat a;
message =
messagesNode.ge tElementsByTagN ame('text')[0].firstChild.dat a;
FormatMessage(d atetime,from,me ssage);
i++;
}
}
}
http.send(null) ;
setTimeout(Refr eshChat,10000);
}
function FormatMessage(d atetime,from,me ssage) {
httpnew.open("G ET","formatmess age.php",true);
httpnew.onready statechange = function() {
if(httpnew.read yState == 4 && httpnew.status == 200) {
alert(httpnew.r eadyState);
formattedmessag e = httpnew.respons eText;
document.getEle mentById('chata rea').innerHTML = formattedmessag e;
}
else {
document.getEle mentById('chata rea').innerHTML = "Error!";
}
}
}
When I run the RefreshChat() function, everything runs fine up to...
httpnew.onready statechange = function() {
in the FormatMessage function, because the state never changes
(readyState is always 1).
Both the php pages (refreshchat.ph p) and (formatmessage. php) exist and
dont timeout or have errors.
