var myRandomDiffElement = myArray.randomDiffElement(lastRandomElement) 1. #2楼 我认为,与其乱搞原型或及时声明它,不如将其暴露在窗口中: AI检测代码解析 window.choice = function() { if (!this.length || this.length == 0) return; if (this.length == 1) return this[0]; return this[Math....
Math.random()方法返回大于等于 0 小于 1 的一个随机数 例:产生1-10的随机数 var rand1 = Math.floor(Math.random() * 10 + 1); 1. 编写产生startNumber至endNumber随机数的函数 function selectFrom(startNumber, endNumber) { var choice = endNumber - startNumber + 1; return Math.floor(Math.ra...

简介:js实现python的random.choice Python代码 import randomnames = ["小红", "小明", "小王"]random.choice(names)'小王' js代码 var names = ["小红", "小明", "小王"];let index = Math.floor((Math.random() * names.length));names[index];"小王"...
To create a random TypeID of a given type, use thetypeid()function: import{typeid}from'typeid-js';consttid=typeid('prefix'); The prefix is optional, so if you need to create an id without a type prefix, you can do that too:
arrayArray-yesArray of elements where we extract one element Examples import{Random}from'randnjs'constnumbers=[1,6,10,24,15]constrandomNumber=Random.choice(numbers)console.log(randomNumber)// Output: 6 for example import{Random}from'randnjs'constfruits=['apple','banana','orange','pineapple',...
