JS代码：
$.ajax({
type: 'POST',
url: 'http://localhost/MyServiceDir/Service.asmx/Foo',
contentType: 'application/json; charset=utf-8',
data: jsonData,
success: function (msg) {
alert("good");
},
error: function (xhr, status) {
switch (status) {
case 404:
alert('File not found');
break;
case 500:
alert('Server error');
break;
case 0:
alert('Request aborted');
break;
default:
alert('Unknown error ' + status);
}
}
});
我收到“未知错误错误”。我如何深入了解这一点？我想知道错误究竟是什么。谢谢！
