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 onreadystatechange
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.php",true);
http.onreadystatechange = function () {
if (http.readyState == 4 && http.status == 200) {
// XML
XML_result = http.responseXML;
docNode = XML_result.documentElement;
msg_count = docNode.getElementsByTagName('message').length;
i = 0;
while(i < msg_count) {
messagesNode = docNode.getElementsByTagName('message')[i];
datetime =
messagesNode.getElementsByTagName('datetime')[0].firstChild.data;
from =
messagesNode.getElementsByTagName('from')[0].firstChild.data;
message =
messagesNode.getElementsByTagName('text')[0].firstChild.data;
FormatMessage(datetime,from,message);
i++;
}
}
}
http.send(null);
setTimeout(RefreshChat,10000);
}
function FormatMessage(datetime,from,message) {
httpnew.open("GET","formatmessage.php",true);
httpnew.onreadystatechange = function() {
if(httpnew.readyState == 4 && httpnew.status == 200) {
alert(httpnew.readyState);
formattedmessage = httpnew.responseText;
document.getElementById('chatarea').innerHTML = formattedmessage;
}
else {
document.getElementById('chatarea').innerHTML = "Error!";
}
}
}
When I run the RefreshChat() function, everything runs fine up to...
httpnew.onreadystatechange = function() {
in the FormatMessage function, because the state never changes
(readyState is always 1).
Both the php pages (refreshchat.php) and (formatmessage.php) exist and
dont timeout or have errors.
