Question

If I’m making a call to an ASMX web service and an exception occurs, the web service will return something like this:

{"Message":"Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).","StackTrace":"   at System.Guid.TryParseGuidWithNoStyle(String guidString, GuidResult& result)\r\n   at System.Guid.TryParseGuid(String g, GuidStyles flags, GuidResult& result)\r\n   at System.Guid..ctor(String g)\r\n   at System.ComponentModel.GuidConverter.ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, Object value)\r\n   at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)\r\n   at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)\r\n   at System.Web.Script.Services.WebServiceMethodData.StrongTypeParameters(IDictionary`2 rawParams)\r\n   at System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters)\r\n   at System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)\r\n   at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.FormatException"}

I’d like to display this message in an alert or jQuery dialog box, but in order to do that, I want to pretty print it. Is there a JS library out there constructed for this purpose?

Answer 1

You don’t need any lib just jquery ui dialog. and also its allreay pretty prented (has spaces and enters)

function show_error(json) {
   $('.error').remove();
   $(document.documentElement).append('<div class="error"><h1><b>' + json['ExceptionType'] + 
      '</b>: ' + json['Message'] + '</h1><pre class="trace">' + json['StackTrace'] + 
      '</pre></div>');
   $('.error').dialog();
}

it will put your stack trace in pre tag.
