Like the XML DOM in IE, the XML HTTP request object has multiple versions, so a function is necessary to make sure you’re using the most recent one:
function createXMLHTTP() {
var arrSignatures = [“MSXML2.XMLHTTP.5.0”, “MSXML2.XMLHTTP.4.0”,
“MSXML2.XMLHTTP.3.0”, “MSXML2.XMLHTTP”,
“Microsoft.XMLHTTP”];
for (var i=0; i < arrSignatures.length; i++) {
try {
var oRequest = new ActiveXObject(arrSignatures[i]);
return oRequest;
} catch (oError) {
//ignore
}
}
throw new Error(“MSXML is not installed on your system.”);
}
