语法

dataview.setUint32(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 32-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.

例子

var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
dataview.setUint32(1, 3);
dataview.getUint32(1); // 3
