原生js实现随机点名
本文实例为大家分享了js实现随机点名的具体代码，供大家参考，具体内容如下
<!DOCTYPE html><html lang='en'><head> <meta charset='UTF-8'> <meta name='viewport' content='width=device-width, initial-scale=1.0'> <title>随机点名</title></head><body> <h1 id='names'>点名</h1> <input type='button' value='开始' id=start_btn> <input type='button' value='结束' id=stop_btn disabled> <script>'../DOM/tools.js'</script> <script> let arrName = ['肖巍', '杨恩', '小菊花', '二狗', '小强', '小????', '弯弯姐', '陈锴', '徐阳', '陈阳吉', '张胜江', '我', '波哥', '阿汤哥', '杰哥', '薛老板']; let names = document.querySelector('h1'); let start_btn = document.querySelector('#start_btn'); let stop_btn = document.querySelector('#stop_btn'); let i, timer; function creatRandom(min, max) { if (!max) { [max, min] = [min, 0]; } let number = parseInt(Math.random() * (max - min + 1) + min); return number; } start_btn.onclick = function () { stop_btn.disabled ? stop_btn.disabled = false : stop_btn.disabled = true; start_btn.disabled ? start_btn.disabled = false : start_btn.disabled = true; timer = setInterval(() => { i = creatRandom(0, arrName.length - 1); names.innerHTML = arrName[i]; }, 100); }; stop_btn.onclick = function () { stop_btn.disabled ? stop_btn.disabled = false : stop_btn.disabled = true; start_btn.disabled ? start_btn.disabled = false : start_btn.disabled = true; console.log(arrName [i]); clearInterval(timer); arrName.splice(i, 1); if(!arrName.length){ start_btn.disabled=true; stop_btn.disabled=true; names.innerHTML = '抽奖完毕'; } }; </script></body></html>
