Question

我想从try-catch语句中获取错误对象的详细信息，例如在Servoy JavaScript框架中报告错误的行号和文件（https://servoy.com/），我该如何处理修改下面的代码示例以显示此信息？

var myObj = {'name':'Bob'}

try {
    var age = myObj.age; // throws error because myObj has no 'age' property
}
catch (e) {
  application.output(e, LOGGINGLEVEL.ERROR); // only outputs message without line number or filename info
}

Answer 1

Servoy的错误对象包含＆＃34; lineNumber＆＃34;和＆＃34; fileName＆＃34;属性。它还包含一个＆＃34; rhinoException＆＃34;包含具有以下方法的对象的属性＆＃34; getMessage（）＆＃34;和＆＃34; getScriptStackTrace（）＆＃34;。

这些属性和消息可用于获取有关错误的详细信息：

var myObj = {'name':'Bob'}

try {
    var age = myObj.age; // throws error because myObj has no 'age' property
}
catch (e) {
  var iLineNumber = e.lineNumber;
  var sFileName = e.fileName;
  var sMessage = e.rhinoException.getMessage();
  var sStackTrace = e.rhinoException.getScriptStackTrace();
  var sMessage = "The following message was detected at line "+iLineNumber+" of the file "+sFileName+". The error message was: "+sMessage+". The full stack trace was: "+sStackTrace;
  application.output(sMessage, LOGGINGLEVEL.ERROR);
}

如何在Servoy框架中获取try-catch的详细错误信息（行号，文件名等）？
