这应该是有效的：

const getRandomNum = (min, max) => Math.floor(Math.random() * (max - min + 1)) + min

这个简单的功能很方便，在任何情况下都可以使用（经过充分测试）。此外，结果的分布已经过充分测试，100%正确。

function randomInteger(pMin = 1, pMax = 1_000_000_000)
//Author: Axel Gauffre. 
//Here: https://stackoverflow.com/a/74636954/5171000
//Inspired by: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/random#getting_a_random_number_between_two_values
//
//This function RETURNS A RANDOM INTEGER between pMin (INCLUDED) and pMax (INCLUDED).
//  - pMin and pMax should be integers.
//  - HOWEVER, if pMin and/or pMax are FLOATS, they will be ROUNDED to the NEAREST integer.
//  - NEGATIVE values ARE supported.
//  - The ORDER of the 2 arguments has NO consequence: If pMin > pMax, then pMin and pMax will simply be SWAPPED.
//  - If pMin is omitted, it will DEFAULT TO 1.
//  - If pMax is omitted, it will DEFAULT TO 1 BILLION.
//
//This function works in ANY cases (fully tested).
//Also, the distribution of the results has been fully tested and is 100% correct.
{
    pMin = Math.round(pMin);
    pMax = Math.round(pMax);
    if (pMax < pMin) { let t = pMin; pMin = pMax; pMax = t;}
    return Math.floor(Math.random() * (pMax+1 - pMin) + pMin);
}

实例

返回1到10之间的随机数：

Math.floor((Math.random() * 10) + 1);

结果可能是：3.

或使用lodash/descore：

_.随机（最小值，最大值）

对于大数字。

var min_num = 900;
var max_num = 1000;
while(true){
    
    let num_random = Math.random()* max_num;
    console.log('input : '+num_random);
    if(num_random >= min_num){
        console.log(Math.floor(num_random));
       break; 
    } else {
        console.log(':::'+Math.floor(num_random));
    }
}

这应该是有效的：

const getRandomNum = (min, max) => Math.floor(Math.random() * (max - min + 1)) + min

尝试使用：

函数随机（最小值，最大值）{return Math.round（（Math.random（）*（Math.abs（max-min）））+min）；}console.log（随机（1，6））；
