var randomnumber = Math.floor(Math.random() * (maximum - minimum + 1)) + minimum;

其他答案没有考虑到0和1这两个完全合理的参数。相反，您应该使用圆形而不是天花板或地板：

function randomNumber(minimum, maximum){
    return Math.round( Math.random() * (maximum - minimum) + minimum);
}

console.log(randomNumber(0,1));  # 0 1 1 0 1 0
console.log(randomNumber(5,6));  # 5 6 6 5 5 6
console.log(randomNumber(3,-1)); # 1 3 1 -1 -1 -1

// Example
function ourRandomRange(ourMin, ourMax) {
    return Math.floor(Math.random() * (ourMax - ourMin + 1)) + ourMin;
}

ourRandomRange(1, 9);

// Only change code below this line.
function randomRange(myMin, myMax) {
    var a = Math.floor(Math.random() * (myMax - myMin + 1)) + myMin;
    return a; // Change this line
}

// Change these values to test your function
var myRandom = randomRange(5, 15);

我的生成0和n之间的随机数的方法，其中n<=10（n除外）：

Math.floor((Math.random() * 10) % n)

这是我在网页上找到的东西：

function randomInt(e,t){return Math.floor(Math.random()*(t-e+1)+e)}

使用以下代码，您可以在给定范围内生成一个随机数数组，而无需重复。

function genRandomNumber(how_many_numbers, min, max) {

    // Parameters
    //
    //   how_many_numbers: How many numbers you want to
    //                     generate. For example, it is 5.
    //
    //   min (inclusive):  Minimum/low value of a range. It
    //                     must be any positive integer, but
    //                     less than max. I.e., 4.
    //
    //   max (inclusive):  Maximum value of a range. it must
    //                     be any positive integer. I.e., 50
    //
    //   Return type: array

    var random_number = [];
    for (var i = 0; i < how_many_numbers; i++) {
        var gen_num = parseInt((Math.random() * (max-min+1)) + min);
        do {
            var is_exist = random_number.indexOf(gen_num);
            if (is_exist >= 0) {
                gen_num = parseInt((Math.random() * (max-min+1)) + min);
            }
            else {
                random_number.push(gen_num);
                is_exist = -2;
            }
        }
        while (is_exist > -1);
    }
    document.getElementById('box').innerHTML = random_number;
}
