Question

Javascript中如何不调用构造函数实例化一个对象？

Answer 1

最简单的，对象字面量啊～

var obj = {};

Answer 2

你是说实例化一个类吧，对于用户自定义的类，

new f(a, b, c)

相当于

// Create a new instance using f's prototype.

var newInstance = Object.create(f.prototype), result;

// Call the function

result = f.call(newInstance, a, b, c),

// If the result is a non-null object, use it, otherwise use the new instance.

result && typeof result === 'object' ? result : newInstance

答案摘自这里

Answer 3

function createPeople(name,age){

   var o = {};

   o.name = name;

   o.age = o.age;

   return o;

}

var people = createPeople('chen',30);
