DataView.prototype.byteOffset - JavaScript | MDN

Baseline Widely available

byteOffset 属性描述了从 ArrayBuffer 开始的字节偏移量。

// Create an ArrayBuffer with a size in bytes
const buffer = new ArrayBuffer(16);

const view = new DataView(buffer, 12, 4); // From byte 12 for the next 4 bytes

console.log(view.byteOffset);
// Expected output: 12

byteOffset 属性是一个获取 (accessor) 属性，它的 set 属性为 undefined，这意味着它是只读的。值在 DataView 被创建时就确定了，且不能改变。

var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
dataview.byteOffset; // 0 (没有指定偏移量)

var dataview2 = new DataView(buffer, 3);
dataview2.byteOffset; // 3 (在构造 DataView 时指定)
