以下是我支持es2015之前版本浏览器的解决方案。它不做任何花哨的原型调整，也不会破坏调试器。

/**  Custom Errors
    // Depends on underscore js
    // This will declare an CustError() class in both 'this' and '_exports' namespaces
    // ctor is optional
    declare_cust_error(function CustError(){}, {ns: [this, _exports], ctor: 
        function cust_err_ctor(instance, clazz, name, msg, info){
            q$.called(arguments)
        }
    })

    // Usage:
    // Second param (pojso) is optional
    try {
        throw CustError.create("foo", {k1: 'v1', k2: 'v2'})
    }catch(ex){
        if(CustError.is_inst(ex)){
            console.error("its a CustError", ex)
        } else {
            throw ex
        }
    }

**/
function declare_cust_error(error_class, opts){
    var p, c, cp
    if(!error_class||!(p=error_class.prototype))throw new Error("error_class must be a Class")
    try{
        c = p.constructor; cp = c.toString()
    }catch(ex){}
    if(!cp || cp.indexOf('function ') != 0 || cp.indexOf('[native code]') > 0)
        throw new Error("error_class must be a classic proto class (pre-es6) but got: " + error_class.toString())

    opts=opts||{}
    
    error_class.__is_cust_error__ = true
    error_class.__cust_error_name__ = c.name

    error_class.create = function cust_error_create(msg, info){
        var instance = new Error(msg)
        instance.info = info
        instance.__is_cust_error__ = true
        instance.__cust_error_name__ = c.name
        if(_.isFunction(opts.ctor)){
            opts.ctor(instance, error_class, c.name, msg, info)
        }
        return instance
    }

    error_class.is_inst = function cust_error_is_inst(instanace){
        return ( (instanace instanceof Error) && instanace.__cust_error_name__ === error_class.__cust_error_name__ )
    }
    
    // Declare error in namespace(s)
    _.each(_.isArray(opts.ns)?opts.ns:[opts.ns], function(ns){ ns[c.name] = error_class })

    return error_class

}

我也遇到过类似的问题。我的错误需要是error和NotImplemented的实例，它还需要在控制台中产生一致的回溯。

我的解决方案:

var NotImplemented = (function() {
  var NotImplemented, err;
  NotImplemented = (function() {
    function NotImplemented(message) {
      var err;
      err = new Error(message);
      err.name = "NotImplemented";
      this.message = err.message;
      if (err.stack) this.stack = err.stack;
    }
    return NotImplemented;
  })();
  err = new Error();
  err.name = "NotImplemented";
  NotImplemented.prototype = err;

  return NotImplemented;
}).call(this);

// TEST:
console.log("instanceof Error: " + (new NotImplemented() instanceof Error));
console.log("instanceof NotImplemented: " + (new NotImplemented() instanceofNotImplemented));
console.log("message: "+(new NotImplemented('I was too busy').message));
throw new NotImplemented("just didn't feel like it");

使用node.js运行的结果:

instanceof Error: true
instanceof NotImplemented: true
message: I was too busy

/private/tmp/t.js:24
throw new NotImplemented("just didn't feel like it");
      ^
NotImplemented: just didn't feel like it

该错误通过了我的所有3个标准，尽管stack属性是非标准的，但在大多数较新的浏览器中都支持它，这在我的情况下是可以接受的。

上面的很多方法都不起作用。

最后一个是一个实际的错误。如果您使用字符串，它看起来很好，但它不会提供堆栈跟踪。如果你抛出错误，你不能有“Uncaught BadError: bad”，所以你必须删除自定义错误(遗憾的是)。如果你抛出一个对象，它看起来有点偏离，最后一个只是一个平均错误。

此方法创建一个具有自定义名称的错误，同时保留堆栈跟踪:

var errProto = Object.create(Error.prototype, { constructor: { value: Error, enumerable: false, writable: true, configurable: true } }) var isFirefox = !!window.InstallTrigger // Hide stack for Firefox only, as stacks can cause problems with high "frame" counts. function createError(name, message, hideStack) { if (message == null) { message = "" } var customError = Error(message) customError.name = name Object.setPrototypeOf(customError, errProto) if (isFirefox && hideStack) { customError.stack = "" } else if (isFirefox) { var stack = customError.stack var newline = stack.indexOf("\n") + 1 stack = stack.slice(newline) customError.stack = stack var split = stack.split(":") if (split.length > 4) { var a = split[3] var b = split[4] var t = b.slice(0, b.indexOf("\n")) customError.lineNumber = Number(a) customError.columnNumber = Number(t) } } else { var stack = customError.stack var split = stack.split("\n") var secondPart = split.slice(2).join("\n") stack = split[0] + "\n" + secondPart customError.stack = stack var split = secondPart.split(":") var a = split[2] var b = split[3] } throw customError } var frame = 0 function aFunction() { if (++frame === 100) { createError("LazyError", "function getting lazy", false, true) } else { requestAnimationFrame(aFunction) } } setTimeout(aFunction, Math.random() * 500) * { font-family: Verdana; } Check your inspector!

以下是Mozilla官方文档中的错误。

function NotImplementedError(message) {
    var instance = new Error(message);
    instance.name = 'NotImplementedError';

    Object.setPrototypeOf(instance, Object.getPrototypeOf(this));
    if (Error.captureStackTrace) {
        Error.captureStackTrace(instance, NotImplementedError);
    }
    return instance;
}

NotImplementedError.prototype = Object.create(Error.prototype, {
    constructor: {
        value: Error,
        enumerable: false,
        writable: true,
        configurable: true
    }
});

class NotImplementedError extends Error {
  constructor(message) {
    super(message);
    this.message = message;
  }
}
NotImplementedError.prototype.name = 'NotImplementedError';
module.exports = NotImplementedError;

and

try {
  var e = new NotImplementedError("NotImplementedError message");
  throw e;
} catch (ex1) {
  console.log(ex1.stack);
  console.log("ex1 instanceof NotImplementedError = " + (ex1 instanceof NotImplementedError));
  console.log("ex1 instanceof Error = " + (ex1 instanceof Error));
  console.log("ex1.name = " + ex1.name);
  console.log("ex1.message = " + ex1.message);
}

它只是这个答案的一个类表示。

输出

NotImplementedError: NotImplementedError message
  ...stacktrace
ex1 instanceof NotImplementedError = true
ex1 instanceof Error = true
ex1.name = NotImplementedError
ex1.message = NotImplementedError message

我只需要实现这样的东西，发现堆栈在我自己的错误实现中丢失了。我要做的是创建一个虚拟错误，并从中检索堆栈:

My.Error = function (message, innerException) {
    var err = new Error();
    this.stack = err.stack; // IMPORTANT!
    this.name = "Error";
    this.message = message;
    this.innerException = innerException;
}
My.Error.prototype = new Error();
My.Error.prototype.constructor = My.Error;
My.Error.prototype.toString = function (includeStackTrace) {
    var msg = this.message;
    var e = this.innerException;
    while (e) {
        msg += " The details are:\n" + e.message;
        e = e.innerException;
    }
    if (includeStackTrace) {
        msg += "\n\nStack Trace:\n\n" + this.stack;
    }
    return msg;
}
