如何从ArrayBuffer获取数组? [英] How to get an array from ArrayBuffer?
问题描述
我有一个ArrayBuffer,看起来像:
I have an ArrayBuffer which looks like:
此缓冲区放置在名为 myBuffer
的变量下,我感兴趣的是从此对象获取 Uint8Array
.
This buffer is placed under variable named myBuffer
and what I'm interested in, is to get the Uint8Array
from this object.
我试图循环为:
myBuffer.forEach(function(element) {
console.log(element);
});
并以以下方式直接访问数组:
and to directly access to the Array as:
console.log(myBuffer['[[Uint8Array]]']);
console.log(myBuffer['Uint8Array']);
但是似乎这都不是正确的方法
but seems none of this is the correct approach
推荐答案
您看到的那些伪属性是开发者控制台为了您的利益而放置的.作为属性或符号(AFAIK),它们根本就不存在,即使它们是非标准的.
Those pseudo-properties you are seeing are something the developer console is putting there for your benefit. They aren't really there at all, as a property or a symbol (AFAIK), and even if they were it would be non-standard.
您可以像这样通过标准方式轻松获得缓冲区的 Uint8Array
视图:
You can easily get a Uint8Array
view of your buffer the standard way like this though:
new Uint8Array(myBuffer)
