生成2个变量之间的随机数 [英] generate random number between 2 variables jquery

问题描述

我需要生成一个介于-100和一个变量'max_top'之间的随机数(将始终是一个正数，最多为40).该数字必须能够为负数，也可以为正数.

i need to generate a random number between -100 and a variable 'max_top' ( will always be a positive number, up to roughly 40). The number needs to be able to be a minus as well as positive.

我该怎么做?

推荐答案

您不需要JQuery:

You dont need JQuery for this:

var minNumber = -100;
var maxNumber = 40

var randomNumber = randomNumberFromRange(minNumber, maxNumber);

function randomNumberFromRange(min,max)
{
    return Math.floor(Math.random()*(max-min+1)+min);
}

console.log(randomNumber);
