DataView.prototype.setInt8() - JavaScript | MDN

Baseline Widely available

setInt8() 从 DataView 起始位置以 byte 为计数的指定偏移量 (byteOffset) 处储存一个 8-bit 数 (一个字节)。

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

const view = new DataView(buffer);
view.setInt8(1, 127); // Max signed 8-bit integer

console.log(view.getInt8(1));
// Expected output: 127

dataview.setInt8(byteOffset, value)

byteOffset

偏移量，从头开始计算，单位为字节

value

设置的整数值

undefined.

RangeError

如果 byteOffset 超出了视图能储存的值，就会抛出错误

var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
dataview.setInt8(1, 3);
dataview.getInt8(1); // 3
