setInt16()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(短整型).

语法

dataview.setInt16(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

undefined.

抛出错误

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.setInt16(1, 3);
dataview.getInt16(1); // 3
