js微信抢红包脚本代码_如何利用JavaScript来实现微信抢红包功能的示例代码

本文通过实例代码给大家介绍了基于JavaScript实现微信抢红包功能，金额随机，额度在0.01和(剩余平均值*2)之间，具体的实例代码大家参考下本文

金额随机：额度在0.01和(剩余平均值*2)之间。

/**

* 抢红包

* @param {[number]} totalAmount [总金额]

* @param {[number]} totalPeople [总人数]

* @return {[Array]} [每个人抢到的金额]

*/

function assign(totalAmount, totalPeople){

var remainAmount = +totalAmount;

var remainPeople = +totalPeople;

var arr = [];

while(remainPeople > 0){

let num = scramble(remainAmount, remainPeople);

remainAmount = remainAmount - num;

remainPeople--;

arr.push(num);

}

return arr;

}

function scramble(remainAmount, remainPeople){

if(remainPeople === 1){

return +remainAmount.toFixed(2);

}

let max = ((remainAmount / remainPeople) * 2 - 0.01).toFixed(2);

let min = 0.01;

let range = max - min;

let rand = Math.random();

let num = min + Math.round(rand * range); //四舍五入

return num;

}

总结
