DataView.prototype.setUint16()
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
setUint16() 从 DataView 起始位置以 byte 为计数的指定偏移量 (byteOffset) 处储存一个 16-bit 数 (无符号短整型)。
尝试一下
语法
dataview.setUint16(byteOffset, value [, littleEndian])
参数
- byteOffset
-
偏移量，从头开始计算，单位为字节。
- value
-
设置的数值。
- littleEndian
-
可选 Indicates whether the 16-bit int is stored in little- or big-endian format. If false or undefined, a big-endian value is written.
返回
抛出错误
RangeError-
如果 byteOffset 超出了视图能储存的值，就会抛出错误。
示例
js
var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
dataview.setUint16(1, 3);
dataview.getUint16(1); // 3
