Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since Juli 2015.
Der Int16Array() Konstruktor erstellt Int16Array Objekte. Der Inhalt wird auf 0 initialisiert, es sei denn, es werden explizit Initialisierungsdaten bereitgestellt.
Syntax
js
new Int16Array()
new Int16Array(length)
new Int16Array(typedArray)
new Int16Array(object)
new Int16Array(buffer)
new Int16Array(buffer, byteOffset)
new Int16Array(buffer, byteOffset, length)
Parameter
Siehe TypedArray.
Ausnahmen
Siehe TypedArray.
Beispiele
Verschiedene Möglichkeiten, eine Int16Array zu erstellen
js
// From a length
const int16 = new Int16Array(2);
int16[0] = 42;
console.log(int16[0]); // 42
console.log(int16.length); // 2
console.log(int16.BYTES_PER_ELEMENT); // 2
// From an array
const x = new Int16Array([21, 31]);
console.log(x[1]); // 31
// From another TypedArray
const y = new Int16Array(x);
console.log(y[0]); // 21
// From an ArrayBuffer
const buffer = new ArrayBuffer(16);
const z = new Int16Array(buffer, 2, 4);
console.log(z.byteOffset); // 2
// From an iterable
const iterable = (function* () {
yield* [1, 2, 3];
})();
const int16FromIterable = new Int16Array(iterable);
console.log(int16FromIterable);
// Int16Array [1, 2, 3]
