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;

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

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.

If that test passes, you must get the alert. When earlier you alert result, presumably it appears to contain "saved|saved" || result == "saved|saved|saved", but are you sure the case matches and there are no boundary whitespace characters?
I think it would be better to use a regex here.

[newphpcoder]

it alerts the :

saved|saved|saved
but the next alert :

alert("Transaction has been saved."); was not

and also it save the data and the textbox was disabled that was happened.it did not display the alert :
alert("Transaction has been saved."); and it did not cleared the textbox

How can I use regex?

Thank you

[Logic Ali]

it alerts the :

saved|saved|saved
but the next alert :

alert("Transaction has been saved."); was not

Try alert( ">" + result + "<" );

You should see

>saved|saved|saved<

not

>saved|saved|saved <

or similar.

Use the test:

if ( /(^|\s)saved\|saved(\|saved)?(\s|$)/.test( result )  )

Hi..

I tried your suggestion and the result is when I input the lotcode and I press the enter key the textbox was disabled then nothing was happened next no alerts displayed

Any console errors?

Can you host a live demo?
