Uint16Array · WebPlatform Docs

A typed array of 16-bit unsigned integer values. The contents are initialized to 0. If the requested number of bytes could not be allocated an exception is raised.

uint16Array = new Uint16Array( length );

uint16Array = new Uint16Array( array );

uint16Array = new Uint16Array( buffer , byteOffset , length );

uint16Array

Required. The variable name to which the Uint16Array object is assigned.

length

Specifies the length (in bytes) of the array.

array

The array (or typed array) that is contained in this array… The contents are initialized to the contents of the given array or typed array, with each element converted to the Uint16 type.

buffer

The ArrayBuffer that the Uint16Array represents.

byteOffset

Optional. Specifies the offset in bytes from the start of the buffer at which the Uint16Array should begin.

length

The length of the array.

The following example shows how to use a Uint16Array object to process the binary data acquired from an XmlHttpRequest:

var req = new XMLHttpRequest();
     req.open('GET', "http://www.example.com");
     req.responseType = "arraybuffer";
     req.send();

     req.onreadystatechange = function () {
         if (req.readyState === 4) {
             var buffer = req.response;
             var dataview = new DataView(buffer);
             var ints = new Uint16Array(buffer.byteLength / 2);
             for (var i = 0; i < ints.length; i++) {
                 ints[i] = dataview.getUint16(i * 2);
             }
         alert(ints[10]);
         }
     }
