我尝试过：
< html>
< head>
< script src =http://ajax.aspnetcdn.com/ajax/jquery/jquery-1.9.0.js>< / script>
< script> < br $>
var url =http://www.webservicex.net/globalweather.asmx;
$（document）.ready（function （）{
$ .ajax（{
类型：POST ，
url：url +/ GetCitiesByCountry，
数据：{CountryName：'IND'}，
contentType：application / JSON; charset = utf-8，
dataType：json，
成功：OnSuccessCall，
错误：OnErrorCall
}）;
函数OnSuccessCall（响应）{
alert（response.d）;
}
函数OnErrorCall（响应）{
alert（response.status ++ response。 statusText）;
}
}）;
< / script>
< / head>

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?

由于提供的细节有限，很难理解问题所在。但在这里，我基于使用AJAX调用Web服务的一般方法给出了一个想法。
我假设，您尝试调用的服务GetCitiesByCountry需要一个名称参数腠ntryName，我猜问题就在你发送这个参数的地方。尝试更改这样的代码，看看它是否有效。
您可以看到我使用JSON.stringify在发送到服务之前格式化输入。
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 usedJSON.stringifyfor formatting the input before sending to the service.
