The errorDetail object is a property of the result object, and it includes detailed information about the Web service transaction. Here are its properties:

code. A machine-readable error code that corresponds to a specific invocation of the callService method.
  • raw. This property exposes the raw Simple Object Access Protocol (SOAP) data packet returned by the Web Service after invoking the callService method.
  • string. A human-readable error message that corresponds to a specific invocation of the callService method.

    The onWSresult() function in the following example reads the above parameters of event.result and prints them in a better explanatory fashion:

    <SCRIPT language="JavaScript">
<!--
var iCallID;
function init() {
  service.useService("/services/math.asmx?WSDL","MyMath");
  iCallID = service.MyMath.callService("add",5,6);
}
function onWSresult() {  
  if((event.result.error)&&(iCallID==event.result.id)) {    
    var xfaultcode   = event.result.errorDetail.code;
    var xfaultstring = event.result.errorDetail.string;    
    var xfaultsoap   = event.result.errorDetail.raw;
    document.writeln("ERROR. Method call failed!");
    document.writeln("Call ID:" + iCallID);
    document.writeln("Fault Code:" + xfaultcode);
    document.writeln("Fault String:" + xfaultstring);
    document.writeln("SOAP Data:" + xfaultsoap);
  }
  else if(event.result.error == false) {
	     document.writeln("Result received without errors!");
	   }
}
// -->
</SCRIPT>
<BODY onload="init()">
<DIV ID="service" STYLE="behavior:url(webservice.htc)" onresult="onWSresult()">
</DIV>
