Use XMLHttpRequest or ActiveX equivalent to create an xml request object

Use XMLHttpRequest or ActiveX equivalent to create an xml request object. Request a single page and alert the results to the browser.





<html>
<head></head>

<body>
<script language="javascript">
var xmlhttp = false;

// If XMLHttpRequest function does not exist (certain versions of IE,
// or if native XMLHTTP support is disabled under the security settings),
// create it to return the activex equivalent.
if(!window.XMLHttpRequest) {
window.XMLHttpRequest = function() {
// For maximum compatibility, try all versions.
var xml_versions=["MSXML2.XMLHTTP.6.0","MSXML2.XMLHTTP.3.0",
"MSXML2.XMLHTTP","Microsoft.XMLHTTP"];
for(var x = 0;x < xml_versions.length; x++) {
try {
return new ActiveXObject(xml_versions[x]);
} catch (e) {}
}
return false;
}
}

if (!xmlhttp && typeof XMLHttpRequest!='undefined') {
try {
xmlhttp = new XMLHttpRequest();
} catch (e) {
xmlhttp = false;
}
}

if(xmlhttp) {
/* .readyState = 0 Uninitialized
.readyState = 1 open() Called
.readyState = 2 send() Called
.readyState = 3 recieving data, .responseText holds partial data in FF
.readyState = 4 data finished */
xmlhttp.onreadystatechange = function() {
if(xmlhttp.readyState == 4) {
alert("RESPONSE HEADERS:\n\n" + xmlhttp.getAllResponseHeaders());
alert("STATUS:\n\n" + xmlhttp.status);
alert("RESPONSE TEXT:\n\n" + xmlhttp.responseText);
}
}

xmlhttp.open("GET", "/?var1=val1&var2=val2");
xmlhttp.send(null);

/* If you want to POST data to recieve_data.php instead
var post_data = 'var1=' + encodeURIComponent('asj$@#&&?') + '&var2=val2';
xmlhttp.open("POST", "recieve_data.php");
xmlhttp.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
xmlhttp.setRequestHeader('Content-length', post_data.length);
xmlhttp.send(post_data); */
}
</script>

</body>
</html>
