typedArray.length是JavaScript中的内置属性,用于返回给定typedArray的长度。句法:
typedArray.length
参数:它不接受任何参数,因为它是属性而不是函数。
返回值:它返回给定typedArray的长度。
代码1:
<script>
// Creating a typedArray with some elements
var A = new Uint8Array([5, 10, 15, 15, 5, 20, 10]);
var B = new Uint8Array([5, 10]);
var C = new Uint8Array([5, 10, 15]);
var D = new Uint8Array([5, 10, 15, 15, 5]);
var E = new Uint8Array([5, 10, 15, 15, 5, 20]);
// Calling length() function
b = A.length
c = B.length
d = C.length
e = D.length
f = E.length
// Printing the length of the typedArray
document.write(b +"<br>");
document.write(c +"<br>");
document.write(d +"<br>");
document.write(e +"<br>");
document.write(f +"<br>");
</script>
输出:
7 2 3 5 6
代码2:
<script>
// Creating some ArrayBuffer with a size in bytes
const A = new ArrayBuffer(8);
const B = new ArrayBuffer(6);
const C = new ArrayBuffer(16);
const D = new ArrayBuffer(32);
// Creating some typedArray with the above sizes
// of the buffer
const E = new Uint8Array(A);
const F = new Uint8Array(B);
const G = new Uint8Array(C);
const H = new Uint8Array(D);
// Calling length property
a = E.length
b = F.length
c = G.length
d = H.length
// Printing the length of the typedArray
document.write(a +"<br>");
document.write(b +"<br>");
document.write(c +"<br>");
document.write(d);
</script>
输出:
8 6 16 32
