Internet Explorer Error : SCRIPT5009: ArrayBuffer is undefined
提问by SalesforceQueries
I am receiving an error in internet explorer 9 and under which does not occur on other browsers. It's:
我在 Internet Explorer 9 中收到错误，在其他浏览器上不会发生。它的：
SCRIPT5009: 'ArrayBuffer' is undefined
SCRIPT5009: 'ArrayBuffer' 未定义
My code is as follows
我的代码如下
var rawLength = raw.length;
var array = new Uint8Array(new ArrayBuffer(rawLength));
for(i = 0; i < rawLength; i++) {
array[i] = raw.charCodeAt(i);
}
The line which breaks is var array = new Uint8Array(new ArrayBuffer(rawLength));
断线是 var array = new Uint8Array(new ArrayBuffer(rawLength));
Does anyone know if there is a solution or workaround for this? I require my functionality to work in all browsers.
有谁知道是否有解决方案或解决方法？我需要我的功能在所有浏览器中工作。

ArrayBufferisn't supported until IE10 (and I think this shows it: http://caniuse.com/typedarrays).
ArrayBuffer直到 IE10 才支持（我认为这表明：http: //caniuse.com/typedarrays）。
You can use a polyfill, and here's one: https://github.com/inexorabletash/polyfill/blob/master/typedarray.js
您可以使用 polyfill，这是一个：https: //github.com/inexorabletash/polyfill/blob/master/typedarray.js
Polyfill taken from: https://github.com/inexorabletash/polyfill
