you could do an ajax request within the medi function and the request could sent it via post to an file like "mehdi_js_result.php" :)

var ajaxify = function(obj) {
        var xmlHttp = null;
        try {
            xmlHttp = new XMLHttpRequest();
        }catch(e) {
            try {
                xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
            }catch(e) {
                try {
                    xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
                }catch(e) {
                    xmlHttp = null;
                }
            }
        }if (xmlHttp) {
            obj.method = obj.method.toUpperCase();
            xmlHttp.open(obj.method, obj.url, true);
            xmlHttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
            if(obj.method == 'POST') {
                if(typeof(obj.params) != 'undefined') {
                    xmlHttp.setRequestHeader("Content-length", obj.params.length);
                }
            }
            xmlHttp.setRequestHeader("Connection", "close");
            xmlHttp.onreadystatechange = function () {
                if (xmlHttp.readyState == 4) {
                    var json = eval(xmlHttp.responseText);
                    if(json.success) {
                        if(typeof(obj.success) == 'function'){obj.success(xmlHttp.responseText);}
                    }
                    else {
                        if(typeof(obj.failure) == 'function') {obj.failure(xmlHttp.responseText);}
                    }
                }
            };
            if(obj.method == 'POST' && typeof(obj.params) != 'undefined') {
                xmlHttp.send(obj.params);
            }
            else {
                xmlHttp.send(null);
            }
        }
    };
    function ajax(mehdi_result) {
        ajaxify({
            method: 'POST',
            url: 'mehdi_js_result.php',
            params: 'result='+result,
            success: function(response) {
                var json = eval(response);
                alert('success callback function! '+json.data);
            },
            failure: function(response) {
                var json = eval(response);
                alert('failure callback function! '+json.data);
            }
        });
    }
