Hi..

I have ajax code for saving data to database
here is my ajax code:

<script type="text/javascript">
var ajaxTimeOut = null;
var ajaxTimeOutOperator = null; 
var responsePHP; // = "no_reply"
var responsePHPOperator;
var changeFocus; //= false;
var transactionWasSaved;

function remoteRequestObject() {
    var ajaxRequest = false;
    try {
        ajaxRequest = new XMLHttpRequest();
    }
    catch(err) {
        try{
            ajaxRequest = new ActiveXObject("MSxml2.XMLHTTP");
        }
        catch(err) {
            try{
                ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
            }
            catch(err){
                // --> change to DOM alert("Not Supported Browser") + err.description;
                notify('Not Supported Browser.');
                return false;
            }
        }
    }
    return ajaxRequest;

//var ajaxRequest; // = remoteRequestObject();
var ajaxRequest = remoteRequestObject();   
var ajaxRequestOperator;
</script>

</script>


<script type="text/javascript">
function reset() {
        // alert ('reset');
       //enable elements
       
       document.getElementById('txtLotCode').disabled = false;
       
       //reset
  
  document.getElementById('txtLotCode').value = "";  
}
</script>

I got problem in function save, even it satisfied this code:

if (result == "saved|saved" || result == "saved|saved|saved") {

but it did not post alert and also not go to reset function.


I don't know why?

Thank you

Oh that's quite a code for ajax, Thanks for posting yours . I dont really get the idea of the problem coz it seems your code is running okay but the output is not portraying the correct one. Better check again all the codes itself might have something to do with it.
