problem with - ajax jquery

Question

i have a problem with this script in firefox 4. I test the same script in chrome and it works, but in FF the load never stops, maybe some problem with the code

<script type="text/javascript">
    $(document).ready(function(){

        var somevar = 'some info';
        var someothervar = 'some other info';
        var data = "var1=somevar&var2=someothervar";

        $.post("chart.php", data, function(theResponse){
            if (theResponse == 'sim') {
                document.write("test");
            }
            else {
                document.write("testone");
            }
        });
    });
</script>

php file have a simple echo "sim";

thanks

I'm thinking the problem is in the document.write, which can have some odd and unexpected behaviors. Try replacing it with an alert for testing purposes. — Zikes

Please clarify what "the load never stops" means? Also, why are you using document.write? — Ruan Mendes

You really can't get away with using "document.write()" for such testing. Change your code like this:

$(document).ready(function(){

    var somevar = 'some info';
    var someothervar = 'some other info';
    var data = "var1=somevar&var2=someothervar";

    $.post("chart.php", data, function(theResponse){
        if (theResponse == 'sim') {
            alert("test");
        }
        else {
            alert("testone");
        }
    });
});

Because the response to the request is very likely to be received after the browser has finished with the original page, the call to "document.write()" will have the effect of obliterating that page.

Beyond that, you can try the TamperData plugin for Firefox (if it's been updated for FF4 ...) to watch the progress of HTTP requests. FireBug will show you XHR requests too.
