JavaScript 在两个数字之间随机
示例
返回介于min和之间的随机整数max:
function randomBetween(min, max) { return Math.floor(Math.random() * (max - min + 1) + min); }
例子:
//randomBetween(0,10); Math.floor(Math.random() * 11); //randomBetween(1,10); Math.floor(Math.random() * 10) + 1; //randomBetween(5,20); Math.floor(Math.random() * 16) + 5; //randomBetween(-10,-2); Math.floor(Math.random() * 9) - 10;
