The byteOffset
accessor property represents the offset (in bytes) of this view from the start of its ArrayBuffer
or SharedArrayBuffer
.
Syntax
dataview.byteOffset
Description
The byteOffset
property is an accessor property whose set accessor function is undefined
, meaning that you can only read this property. The value is established when an DataView
is constructed and cannot be changed.
Examples
Using the byteOffset
property
var buffer = new ArrayBuffer(8); var dataview = new DataView(buffer); dataview.byteOffset; // 0 (no offset specified) var dataview2 = new DataView(buffer, 3); dataview2.byteOffset; // 3 (as specified when constructing the DataView)
