javascript - 如何对包含数组的javascript对象进行排序？

Question

我有一个名为类的对象，它看起来像这样:

Object {d1: Array[6], a1: Array[6]};

我添加一个新数组:classes.b1 = [{"id":1,"vprasan":true},{"id":2,"vprasan":true}]

如何对这个对象进行排序，使其看起来像这样:Object {a1: Array[6], b1: Array[6], d1: Array[6]};

Answer 1

你不能。 JavaScript 对象中的属性顺序未定义。

对象的定义来自ECMAScript Third Edition (pdf) :

4.3.3 Object
An object is a member of the type Object. It is an unordered collection of properties each of which contains a primitive value, object, or function. A function stored in a property of an object is called a method.
