Hello,

I am trying to call a publicly available asmx web service()[^] by an ajax call from visual studio.
But I am not able to do that as i am getting error status message code as 0.

Can anyone tell me where I am going wrong?

Regards,
Swayam

What I have tried:

<html>
<head>
<script src="http://ajax.aspnetcdn.com/ajax/jquery/jquery-1.9.0.js"></script>
<script>
var url = "http://www.webservicex.net/globalweather.asmx";

$(document).ready(function () {

$.ajax({
type: "POST",
url: url + "/GetCitiesByCountry",
data: "{CountryName:'IND'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: OnSuccessCall,
error: OnErrorCall
});

function OnSuccessCall(response) {
alert(response.d);
}

function OnErrorCall(response) {
alert(response.status + " " + response.statusText);
}
});

</script>
</head>
</html>

According to samples HTTP POST does not support JSON as data format, but url-encoded only...

With the limited details provided, it is difficult to understand what the issue is. But here, I am giving an idea based on the general way of calling web service using AJAX.

I assume, the service GetCitiesByCountry, you are trying to call expects a parameter of name CountryName and I guess the issue is in the place where you send this parameter. Try changing the code like this and see if it works.

You can see I used JSON.stringify for formatting the input before sending to the service.

JavaScript

var url = "http://www.webservicex.net/globalweather.asmx";

$(document).ready(function () {
 var input = { CountryName: "IND" };
$.ajax({
type: "POST",
url: url + "/GetCitiesByCountry",
data: JSON.stringify(input),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: OnSuccessCall,
error: OnErrorCall
});

function OnSuccessCall(response) {
alert(response.d);
}


function OnErrorCall(response) {
alert(response.status + " " + response.statusText);
}
});
