thanks for any suggestions

The pastebin code already does this. I'm guessing that the problem you're actually facing exists because your ajax call is asynchronous, which means that you're making the ajax request (asynchronously), and immediately trying to access the value in the global variable - but it hasn't been set yet.

The solution to this is to execute your post-ajax code in the onReadyStateChange callback.

function handleResponse(result_cont) {
    // your result_cont processing code here
}

ajax(handleResponse);

function ajax(callback) {
    var xmlHttp;
    try { // Firefox, Opera 8.0+, Safari
        xmlHttp = new XMLHttpRequest();
    } catch (e) {
        // Internet Explorer
        try {
            xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
        } catch (e) {
            try {
                xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
            } catch (e) {
                return false;
            }
        }
    }
    xmlHttp.onreadystatechange = function () {
        if (xmlHttp.readyState == 4) {
            if (xmlHttp.responseText != "") {
                result_cont = xmlHttp.responseText
                alert(result_cont);

                // ############# here's the important change #############
                // execute the provided callback
                callback(result_cont);
            }
        }
    }
    xmlHttp.open("GET", "contentdetails.php?cid=1", true);
    xmlHttp.send(null);
}
