麻烦在JavaScript上述字符code 128二进制字符串 [英] Trouble with binary string in javascript above character code 128
问题描述
所以我想创建并保存一个二进制文件本地JavaScript中使用这个库：的https： //github.com/eligrey/FileSaver.js/
So I'm trying to create and save a binary file locally in javascript using this library: https://github.com/eligrey/FileSaver.js/
这是一个有点棘手，因为我使用的游戏制作工作室，我可以使用JavaScript的互动方式是有点有限，但这里是我的设置..
除了从GitHub库的实际filesaver.js，我的js code是这样的：
It is a bit tricky because I am using GameMaker studio, and the ways I can interact with the javascript is a bit limited, but here's my setup.. Other than the actual filesaver.js from the github repo, my js code is this:
var ildablob = new Array();
toArray = function(argument0, argument1)
{
ildablob[argument0] = String.fromCharCode(argument1);
return 1;
}
save = function(argument0)
{
var blob = new Blob(ildablob, {type: "application/octet-stream"});
saveAs(blob, argument0);
return 1;
}
基本上，这个想法是，我首先填充使用字符codeS创建一个二进制字符串，然后做成一个blob，并保存单个字节数组。这适用于低于128二进制值，而不是上述原因，可能是因为一些字符集问题..我该如何解决这个问题？
Basically, the idea is that I first fill up an array with individual bytes using character codes to create a binary string, which is then made into a blob and saved. This works for binary values below 128, but not above, probably because of some charset issue.. How can I fix this?
例如，如果我尝试填补了阵列0-255递增，这是生成的二进制文件的内容，你可以经过128个字节中看到的字符突然创建两个字节的每一个，而不是一个，这一切都错误：
For example, if I try filling up the array incrementing from 0-255, this is the content of the resulting binary file, as you can see after 128 bytes the characters suddenly create two bytes each, not one, and it's all wrong:

推荐答案
而不是使用的字符串，你可能会更好使用 Uint8Array （即范围为0＆ndash的无符号字节数组; 255）;看的https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array.例如：
Instead of using a String, you'd probably be better off using a Uint8Array (meaning an array of unsigned bytes in the range 0–255); see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array. For example:
ildablob[argument0] = new Uint8Array(1);
ildablob[argument0][0] = argument1;
...
var blob = new Blob(ildablob, {type: "application/octet-stream"});
另外，顺便说一句＆MDASH; argument0 和参数1 是可怕的可变名。你提到你被游戏制作的制约;就是这样做的原因？好像应该有某种方式来解决这个问题。
Also, incidentally — argument0 and argument1 are terrible variable-names. You mention that you're constrained by GameMaker; is that the reason for this? It seems like there should be some way to fix that.
