JavaScript在浏览器中是否支持ByteArray类？ [英] Does JavaScript support a ByteArray class in the browser?

问题描述

ByteArray 类提供了用于优化读取，写入和使用二进制数据的方法和属性。

如何使用字节数组教程。

我正在寻找一种与链接的API非常相似的API。

我正在寻找浏览器不提供hack或解决方法的类。链接的问题未提供答案。如果有，请提供文档链接。

有些人链接到另一个问题，但是没有回答我的问题。

更新：不在名单上的人向我指出了此类：

https://gist.github.com/sunetos/275610#file-bytearray-js

它具有大多数或所有读取方法，但没有任何写入方法，并且不是浏览器的本机。

解决方案

现代浏览器支持 Uint8Array ，即JavaScript的 TypedArray 类。

  var data = new Uint8Array（8）; 
 var data = new Uint8Array（[0x10，0x12]）; 
  

它没有用于编码/解码Unicode字符串的内置方法。有关如何执行此操作的示例，请参见在字符串和ArrayBuffer之间进行转换。

The ByteArray class provides methods and properties to optimize reading, writing, and working with binary data.

I'm looking for a very similar API as the one linked.

I'm looking for a class the browser provides not hack or workaround. The linked question does not provide the answer. If it does please provide a link to the documentation.

Some one linked to another question but that did not answer my question.

Update: Someone off list pointed me to this class:

https://gist.github.com/sunetos/275610#file-bytearray-js

It has most or all of the read methods but none of the write methods and it's not native to the browser.

解决方案

Modern browsers support Uint8Array, one of JavaScript's TypedArray classes.

var data = new Uint8Array(8);
var data = new Uint8Array([0x10, 0x12]);

It does not have built-in methods for encoding/decoding Unicode strings. See Converting between strings and ArrayBuffers for examples of how to do that.
