Ajax Asynchronous in IE - Error "The Data Necessary to Complete This Operation is Not Yet Available"
- by Supernovah
Hey there.
I have a 100% valid Ajax model written in Javascript with a few inputs I use being, Get or Post method, What page to communicate with, What String to send to that page and What element on my own page I might be fiddling with when I receive my response.
The problem is that, should I set the request to Asynchronous (Hence Ajax), IE returns the error "The Data Necessary to Complete This Operation is Not Yet Available" in the onreadystatechange event where all I do is check if the readystate is 4 and the status is 200. The error doesn't come up in Firefox or Chrome as I would exepect as the Ajax is Asynchronous.
Heres a snippet from the Post method
xmlhttp.open("POST", commPage, true);
xmlhttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded; charset=UTF-8");
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
j = xmlhttp.responseText;
i.innerHTML = j;
}
}
xmlhttp.send(str);
Edit: I should point out that in IE, I'm using the ActiveX Control - Msxml2.XMLHTTP or Microsoft.XMLHTTP or whichever returns true first.
