ArrayBuffer.prototype

The ArrayBuffer.prototype property represents the prototype for the ArrayBuffer object.

ArrayBuffer.prototype属性表示ArrayBuffer的原型对象。

Description（描述）

ArrayBuffer instances inherit from ArrayBuffer.prototype. As with all constructors, you can change the constructor's prototype object to make changes to all ArrayBuffer instances.

ArrayBuffer 实例继承自ArrayBuffer.prototype。因为所有的构造器继承自ArrayBuffer.prototype，所以你可以通过改变原型对象的构造器来改变所有的ArrayBuffer实例。

Properties（属性）

ArrayBuffer.prototype.constructor

Specifies the function that creates an object's prototype. The initial value is the standard built-in ArrayBuffer constructor.

指定创建原型对象的函数。其初始值是ArrayBuffer内建的标准构造器。

 

ArrayBuffer.prototype.byteLength 只读

The size, in bytes, of the array. This is established when the array is constructed and cannot be changed. Read only.

字节大小。在ArrayBuffer实例被创建时产生的不可更改的只读属性。

Methods（方法）

ArrayBuffer.prototype.slice()

Returns a new ArrayBuffer whose contents are a copy of this ArrayBuffer's bytes from begin, inclusive, up to end, exclusive. If either begin or end is negative, it refers to an index from the end of the array, as opposed to from the beginning.

返回一个新的子数组副本，从包含起始下标到结束下标减1。若起始下标为负则表示从0开始，若结束下标为负则表示到末尾。
