语法

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 32-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.
例子
var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
dataview.setInt32(1, 3);
dataview.getInt32(1); // 3
