javascript - 如何在javascript中弹出数组中的元素？

Question

如何从数组中弹出随机选择的内容？
var number = ["a", "b", "c"];
var random = number[Math.floor(Math.random()*number.length)];

Answer 1

使用拼接

var number = ["a", "b", "c"];
var random = Math.floor(Math.random()*number.length);

console.log(number[random], ' is chosen');
var taken = number.splice(random, 1);

console.log('after removed, ', number);
console.log('number taken, ', taken);
