DataView.prototype.getBigUint64()

getBigUint64() 方法，从 DataView 的指定偏移量位置获取一个无符号 64 位整数 (unsigned long long)。

尝试一下

语法

dataview.getBigUint64(byteOffset [, littleEndian])

参数

byteOffset

偏移量，按字节偏移，从 DataView 读取一个整数

littleEndian

可选 指出 64 位整数以 little- or big-endian 类型存储。如果值为 false or undefined, 读取一个大端数值。

返回值

A BigInt.

异常

RangeError

Thrown if the byteOffset is set such that it would read beyond the end of the view.

Description

There is no alignment constraint; multi-byte values may be fetched from any offset.

Examples

Using the getBigUint64 method

var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
dataview.getBigUint64(0); // 0n
