Javascript - 将整数转换为位数组 [英] Javascript - convert integer to array of bits

问题描述

我正在尝试使用javascript将一个整数（我知道将在0到32之间）转换为0和1的数组。我环顾四周但找不到合适的东西..

I am trying in javascript to convert an integer (which I know will be between 0 and 32), to an array of 0s and 1s. I have looked around but couldn't find something that works..

所以，如果我有一个22的整数（二进制10110），我想访问它：

So, if I have an integer as 22 (binary 10110), I would like to access it as:

Bitarr[0] = 0
Bitarr[1] = 1
Bitarr[2] = 1
Bitarr[3] = 0
Bitarr[4] = 1

有什么建议么？
非常感谢

Any suggestions? Many thanks

推荐答案

转换为基数2：

var base2 = (yourNumber).toString(2);

访问字符（位）：

base2[0], base2[1], base2[3], etc...
