guys …
i have use the ajax http request to do smart refresh…and it work fine when i am using the apache webserver….
however, when i wanna run it on the tomcat webserver, it seem to keep prompting error mssg..
the system keep prompting alert (this code always run) :
alert(‘There was a problem with the request.’);
here is my code:
<script language=”JavaScript”>
setTimeout(‘get()’,1000);
var http_request = false;
function makePOSTRequest(url, parameters) {
http_request = false;
if (window.XMLHttpRequest) { // Mozilla, Safari,…
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType) {
// set type accordingly to anticipated content type
//http_request.overrideMimeType(‘text/xml’);
http_request.overrideMimeType(‘text/html’);
}
} else if (window.ActiveXObject) { // IE
try {
http_request = new ActiveXObject(“Msxml2.XMLHTTP”);
} catch (e) {
try {
http_request = new ActiveXObject(“Microsoft.XMLHTTP”);
} catch (e) {}
}
}
if (!http_request) {
alert(‘Cannot create XMLHTTP instance’);
return false;
}
http_request.onreadystatechange = alertContents;
http_request.open(‘POST’, url, true);
http_request.setRequestHeader(“Content-type”, “application/x-www-form-urlencoded”);
http_request.setRequestHeader(“Content-length”, parameters.length);
http_request.setRequestHeader(“Connection”, “close”);
http_request.send(parameters);
setTimeout(‘get()’,1000);
}
function alertContents() {
if (http_request.readyState == 4) {
if (http_request.status == 200) {
var sentID = http_request.responseText;
if (sentID != “”) {
var sessID = “<? echo $_SESSION[‘userID’]; ?>”;
if (sentID == sessID) {
self.location.reload();
}
}
} else {
alert(‘There was a problem with the request.’);
}
}
}
function get() {
var poststr = “userID=<? echo $_SESSION[‘userID’]; ?>”;
makePOSTRequest(‘server_mainlist.php’, poststr);
}
</script>
