Javascript getting response value after post

Question

I'm triying to post web service. But i want to get response value. My code is shown below:

 var xmlhttp = new XMLHttpRequest();
        xmlhttp.open('POST', 'http://www.w3schools.com/webservices/tempconvert.asmx',  true);

        // build SOAP request
        var sr =
            '<soapenv:Envelope' + ' ' +
                'xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ' +
                'xmlns:api="http://127.0.0.1/Integrics/Enswitch/API" ' +
                'xmlns:xsd="http://www.w3.org/2001/XMLSchema" ' +
                'xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">' +
                '<soapenv:Body>' +
                    '<CelsiusToFahrenheit  xmlns="http://tempuri.org/">' +
                    '<Celsius>44</Celsius>' +
                    '</CelsiusToFahrenheit>'+
                '</soapenv:Body>' +
            '</soapenv:Envelope>';

        xmlhttp.onreadystatechange = function () {
            if (xmlhttp.readyState == 4) {
                if (xmlhttp.status == 200) {

                    alert('done use firebug to see response');
                }
            }
        }
        // Send the POST request
        xmlhttp.setRequestHeader('Content-Type', 'text/xml');
        xmlhttp.send(sr);

When i look in firebug, i realized web server response value is:

<?xml version="1.0" encoding="utf-8"?><soap:Envelope      xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><CelsiusToFahrenheitResponse xmlns="http://tempuri.org/"><CelsiusToFahrenheitResult>111.2</CelsiusToFahrenheitResult>   </CelsiusToFahrenheitResponse></soap:Body></soap:Envelope>

But i dont know how can i get 111.2 value?

You are getting an xml response from your ajax call. Do do it correctly, you need to parse the xml code.

You can do easily it with jQuery:

var r = $(this.responseText).find("CelsiusToFahrenheitResult").text();

I did alert($(this.responseText).find("CelsiusToFahrenheitResult").text()); But i got nothing except white alert window – ftdeveloper Jul 29 '13 at 10:30
try alert(this.response) to see if you get the result of the request – Sebastien Jul 29 '13 at 10:31

In your onreadystatechange function, i think you should use this.readState and this.status – Sebastien Jul 29 '13 at 10:32
