javascript - 为什么我的 javascript 不与网页交互？

问题描述

我创建了一个随机数生成器，并使用 document.querySelector('#score-0').textContent = dice; 将它与我的网页中的一个 ID 链接起来。但它不与网页交互？不互动

这是JSBIN中html css和js代码的链接：https ://jsbin.com/lexojiyumi/1/edit?html,css,js,console

var scores, roundScore, activePlayer, dice;
scores = [0, 0];
roundScore = 0;
activePlayer = 0;

dice = Math.floor(Math.random() * 6) + 1;
console.log(dice);
document.querySelector('#score-0').textContent = dice;

解决方案

您的按钮中缺少onclick事件。roll添加它，它的工作原理：

var scores, roundScore, activePlayer, dice;
scores = [0, 0];
roundScore = 0;
activePlayer = 0;

function roll(){
  debugger
  dice = Math.floor(Math.random() * 6) + 1;
  console.log(dice);
  document.querySelector('#score-0').textContent = dice;
}
//initial roll
roll();
.final-score {
    position: absolute;
    left: 50%;
    transform: translateX(-50%);
    top: 520px;
    color: #555;
    font-size: 18px;
    font-family: 'Lato';
    text-align: center;
    padding: 10px;
    width: 160px;
    text-transform: uppercase;
}

.final-score:focus { outline: none; }

#dice-1 { top: 120px; }
#dice-2 { top: 250px; }
