ArrayBuffer.prototype

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

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.

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

ArrayBuffer.prototype.byteLength Read only

陣列大小，以位元組（byte）計算。此屬性在陣列建立之後就不可能改變了。唯讀。

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.
