dataView.setUint16

The setUint16() method stores an unsigned 16-bit integer (unsigned short) value at the specified byte offset from the start of the DataView.

Syntax

dataview.setUint16(byteOffset, value [, littleEndian])

Parameters

byteOffset

The offset, in byte, from the start of the view where to store the data.

value

The value to set.

littleEndian

Optional Indicates whether the 16-bit int is stored in little- or big-endian format. If false or undefined, a big-endian value is written.

Return value

undefined.

Errors thrown

RangeError

Thrown if the byteOffset is set such as it would store beyond the end of the view.

Examples

Using the setUint16 method

var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
dataview.setUint16(1, 3);
dataview.getUint16(1); // 3
