DataView.prototype.setBigUint64()

您正在阅读此内容的英文版本，因为该语系尚未翻译。 帮助我们翻译此文章吧！

The setBigUint64() method stores an unsigned 64-bit integer (unsigned long long) value at the specified byte offset from the start of the DataView.

Syntax

dataview.setBigUint64(byteOffset, value [, littleEndian])

Parameters

byteOffset
The offset, in bytes, from the start of the view to store the data from.
value
The value to set as a BigInt. The highest possible value that fits in an unsigned 64-bit integer is 2n ** 64n - 1n (18446744073709551615n). Upon overflow, it will be zero (0n).
littleEndian
Optional Indicates whether the 64-bit int is stored in little- or big-endian format. If false or undefined, a big-endian value is written.

Return value

undefined.

Errors thrown

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

Examples

Using the setBigUint64 method

var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
dataview.setBigUint64(0, 3n);
dataview.getBigUint64(0); // 3n
