Is there a Javascript library to parse and pretty print .NET exceptions returned as JSON?
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, GuidResu开发者_Python百科lt& 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?
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.
No library that I know of, but this should get you started... save as an .html File for an example:
<html>
<head>
<style type="text/css">
/*Style it here*/
.msgContainer
{
font-family:Arial;
border:solid 1px black;
}
.msgTitle
{
background-color:#FBEC5D;
height:30px;
line-height:30px;
}
.msgBody
{
font-size:10pt;
background-color:#E8E8E8;
}
.msgType
{
font-size:12pt;
font-weight:bold;
color:red;
}
</style>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
//Document Ready: Everything inside this function fires after the page is loaded
$(document).ready(function () {
var prettyPrint = {
EndingsToBreaks: function(str) {
var br = '<br />';
return str.replace( /\r\n|\r|\n/g, br );
},
DisplayError:function(error, divID){
var $Dest = $('#' + divID);
var _msg = this.EndingsToBreaks(error.Message);
var _sTrace = this.EndingsToBreaks(error.StackTrace);
var _sType = this.EndingsToBreaks(error.ExceptionType);
$Dest.append("<div class='msgContainer' ><div class='msgTitle'><span class='msgType'>" + _sType + "</span>:" + _msg + "</div><div class='msgBody'>" +_sTrace+ "</div></div>");
}
}
//Get your error Message
var testError = {"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"}
//Format & Style it...
prettyPrint.DisplayError(testError, "dvMessage");
});
</script>
</head>
<body>
<div id="dvMessage"></div>
</body>
</html>
