JavaScript文件到byte [] [英] JavaScript file to byte[]

问题描述

是否有可能从JavaScript中的路径中读取文件并创建该文件的一个字节[？]？

解决方案

JavaScript有两种形式：客户端和服务器端。在客户端JavaScript中，这是不可能的，而在服务器端JavaScript中，是可能的。所以这取决于你使用的是客户端还是服务器端的JavaScript。

也就是说，客户端JavaScript更常见，如果你使用的是服务器端JavaScript，一边JavaScript，你可能会知道你的问题的答案。所以，我将要走出困境，并说否，不可能从JavaScript中读取路径并从该文件创建一个字节[/ strong]。

（另外，还不清楚你用byte []表示的意思，在使用JavaScript的时候这不是一个常见的表示法，你确定不是在谈论Java吗？Java与JavaScript完全不同：在Java中byte []是一个更常见的符号。）

Is it possible to read a file in from a path in JavaScript and create a byte[] of that file?

解决方案

There are two forms of JavaScript: client-side and server-side. In client-side JavaScript it is not possible, while in server-side JavaScript, it is possible. So it depends on whether you are using client-side or server-side JavaScript.

That said, client-side JavaScript is much more common and if you were using server-side JavaScript, you would probably know the answer to your question. So I'm going to go out on a limb and say that no, it is not possible to read in from a path in JavaScript and create a byte[] from that file.

(Also, it's unclear what you mean by a byte[]; that's not a common notation when using JavaScript. Are you sure you aren't talking about Java? Java is completely different from JavaScript: in Java byte[] is a more common notation.)
