如何在javascript中检索构造函数的名称?

function C() { }

var x = new C();

console.log(x.constructor.name);

x.constructor C true

obj.constructor.toString().match(/function (\w*)/)[1];

on this page

function Foo() {}
Foo.prototype.type = 'Foo';

x.constructor C

function C() { };
x = new C();

x.constructor.toString() x.constructor.name

^{https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Function/name}

var C = function C() { };

C

x = new C();    

console.log(x.constructor.name); // output: C

this.default.name
