[SOLVED] Ajax form submit and encoding problem

[aliento]

Is a form submit script with ajax and i cant make it UTF-8  , do you have any idea?

 function xmlhttpPost(strURL,formname,responsediv,responsemsg) {
    var xmlHttpReq = false;
    var self = this;    


    // Xhr per Mozilla/Safari/Ie7
    if (window.XMLHttpRequest) {
        self.xmlHttpReq = new XMLHttpRequest();
    }
    // per tutte le altre versioni di IE
    else if (window.ActiveXObject) {
        self.xmlHttpReq = new ActiveXObject("Microsoft.XMLHTTP");
            
    } 
    self.xmlHttpReq.open('POST', strURL, true);
    self.xmlHttpReq.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8');

   

    self.xmlHttpReq.onreadystatechange = function() {
        if (self.xmlHttpReq.readyState == 4) {
		// Quando pronta, visualizzo la risposta del form
            updatepage(self.xmlHttpReq.responseText,responsediv);
        }
	else{
		// In attesa della risposta del form visualizzo il msg di attesa
		updatepage(responsemsg,responsediv);

	}
    }
    self.xmlHttpReq.send(getquerystring(formname));
}

function getquerystring(formname) {
    var form = document.forms[formname];
var qstr = "";

    function GetElemValue(name, value) {
        qstr += (qstr.length > 0 ? "&" : "")
            + escape(name).replace(/\+/g, "%2B") + "="
            + escape(value ? value : "").replace(/\+/g, "%2B");
		//+ escape(value ? value : "").replace(/\n/g, "%0D");
    }

var elemArray = form.elements;
    for (var i = 0; i < elemArray.length; i++) {
        var element = elemArray[i];
        var elemType = element.type.toUpperCase();
        var elemName = element.name;
        if (elemName) {
            if (elemType == "TEXT"
                    || elemType == "TEXTAREA"
                    || elemType == "PASSWORD"
				|| elemType == "BUTTON"
				|| elemType == "RESET"
				|| elemType == "SUBMIT"
				|| elemType == "FILE"
				|| elemType == "IMAGE"
                    || elemType == "HIDDEN")
                GetElemValue(elemName, element.value);
            else if (elemType == "CHECKBOX" && element.checked)
                GetElemValue(elemName, 
                    element.value ? element.value : "On");
            else if (elemType == "RADIO" && element.checked)
                GetElemValue(elemName, element.value);
            else if (elemType.indexOf("SELECT") != -1)
                for (var j = 0; j < element.options.length; j++) {
                    var option = element.options[j];
                    if (option.selected)
                        GetElemValue(elemName,
                            option.value ? option.value : option.text);
                }
        }
    }
    return qstr;
}
function updatepage(str,responsediv){


    document.getElementById(responsediv).innerHTML = str;
}

i found solution.

Ajax can't send multybyte utf-8.

 

I use a pregmatch on serverside to convert it to utf-8.

 

 

$retval = utf8_encode( preg_replace("/%u([0-9a-f]{3,4})/i","&#x\\1;",urldecode($retval)) );
