function FooFactory() {
    var prototype, F = function(){};

    function Foo() {
        var args = Array.prototype.slice.call(arguments),
            i;     
        for (i = 0, this.args = {}; i < args.length; i +=1) {
            this.args[i] = args[i];
        }
        this.bar = 'baz';
        this.print();

        return this;
    }

    prototype = Foo.prototype;
    prototype.print = function () {
        console.log(this.bar);
    };

    F.prototype = prototype;

    return Foo.apply(new F(), Array.prototype.slice.call(arguments));
}

var foo = FooFactory('a', 'b', 'c', 'd', {}, function (){});
console.log('foo:',foo);
foo.print();

这个答案有点晚了，但我想任何看到这个的人都可以使用它。有一种方法可以使用apply返回一个新对象。尽管它需要对对象声明做一点更改。

function testNew() {
    if (!( this instanceof arguments.callee ))
        return arguments.callee.apply( new arguments.callee(), arguments );
    this.arg = Array.prototype.slice.call( arguments );
    return this;
}

testNew.prototype.addThem = function() {
    var newVal = 0,
        i = 0;
    for ( ; i < this.arg.length; i++ ) {
        newVal += this.arg[i];
    }
    return newVal;
}

testNew( 4, 8 ) === { arg : [ 4, 8 ] };
testNew( 1, 2, 3, 4, 5 ).addThem() === 15;

为了让第一个if语句在testNew中工作，你必须返回这个;在函数的底部。以代码为例:

function Something() {
    // init stuff
    return this;
}
function createSomething() {
    return Something.apply( new Something(), arguments );
}
var s = createSomething( a, b, c );

更新:我改变了我的第一个例子的总和参数的数量，而不是只有两个。

不含ES6或polyfills的解决方案:

var obj = _new(Demo).apply(["X", "Y", "Z"]);


function _new(constr)
{
    function createNamedFunction(name)
    {
        return (new Function("return function " + name + "() { };"))();
    }

    var func = createNamedFunction(constr.name);
    func.prototype = constr.prototype;
    var self = new func();

    return { apply: function(args) {
        constr.apply(self, args);
        return self;
    } };
}

function Demo()
{
    for(var index in arguments)
    {
        this['arg' + (parseInt(index) + 1)] = arguments[index];
    }
}
Demo.prototype.tagged = true;


console.log(obj);
console.log(obj.tagged);

输出 演示{arg1: "X"， arg2: "Y"， arg3: "Z"} …或者“更短”的方式:

var func = new Function("return function " + Demo.name + "() { };")();
func.prototype = Demo.prototype;
var obj = new func();

Demo.apply(obj, ["X", "Y", "Z"]);

编辑: 我认为这可能是一个很好的解决方案:

this.forConstructor = function(constr)
{
    return { apply: function(args)
    {
        let name = constr.name.replace('-', '_');

        let func = (new Function('args', name + '_', " return function " + name + "() { " + name + "_.apply(this, args); }"))(args, constr);
        func.constructor = constr;
        func.prototype = constr.prototype;

        return new func(args);
    }};
}

看看CoffeeScript是如何做到的。

([a,b,c]…)

就变成:

var s;
s = (function(func, args, ctor) {
  ctor.prototype = func.prototype;
  var child = new ctor, result = func.apply(child, args);
  return Object(result) === result ? result : child;
})(Something, [a, b, c], function(){});

其实最简单的方法是:

function Something (a, b) {
  this.a = a;
  this.b = b;
}
function createSomething(){
    return Something;
}
s = new (createSomething())(1, 2); 
// s == Something {a: 1, b: 2}

这个工作!

var cls = Array; //eval('Array'); dynamically
var data = [2];
new cls(...data);
